ENDOSCOPIC TREATMENT TOOL AND WATER SUPPLY MEMBER

DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 07/24/2026 has been entered. Response to Amendment This office action is responsive to the amendment filed on 07/24/2026. As directed by the amendment: claims 1, 14, and 15 have been amended and claims 5, 9, 12, and 16-21 remain withdrawn (see non-final office action mailed 08/25/2025). Thus, claims 1-21 are presently pending in this application. Response to Arguments Applicant’s arguments, see pages 9-11, filed 07/24/2026, with respect to the rejection(s) of claim(s) 14-15 under 35 U.S.C. 102(a)(1) as being anticipated by Ishikawa et al (US 20210106375 A1), herein referenced to as “Ishikawa” have been fully considered and are persuasive. The applicant has amended claims 14 and 15 to further recite “and a second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening”. The applicant asserts that Ishikawa does not disclose this second state with the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. The examiner agrees. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Ishikawa in view of Motai et al (US 20200038043 A1). Applicant's arguments, see page 12, filed 07/24/2026, with respect to rejection of claim 1 under 35 U.S.C. 103 as being unpatentable over Ishikawa in view of Motai et al (US 20200038043 A1), herein referenced to as “Motai” have been fully considered but they are not persuasive. The applicant amended claim 1 to further recite “and a second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening”. The applicant asserts that Ishikawa does not disclose this second state with the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. The examiner agrees. However, Motai teaches that in a second state in which the treatment tool main body 170 is entirely retracted toward the proximal end side (see Fig. 13, [0069], the entirety of 170 moves inside the second lumen 30 of 10) with respect to the first opening the distal opening of 10 (see Fig. 13). As such the rejection of claim 1 will be maintained. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-4, 6-8, 10-11, and 13-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishikawa in view of Motai et al (US 20200038043 A1), herein referenced to as “Motai”. Claim 1 Ishikawa discloses: An endoscopic treatment tool 10 (see Figs. 1-6 and 8, [0041]-[0042]) comprising: a treatment tool main body 14 (see Figs. 1 and 4, [0043]) of which a distal end part 16 (see Figs. 1-6, and 8, [0043]) which extends in a first direction the distal direction (see Figs. 1 and 4, 16 extends in the distal direction from 14); an operation member 22 (see Figs. 1-5, [0043]) that is provided on a proximal end side proximal side of 14 (see Fig. 4, [0045]) of the treatment tool main body 14; and an accommodating member 18 + 12 (see Figs. 1-6 and 8, [0043] and [0046]) that has a tubular shape (see Figs. 1-6 and 8, 18 has a generally tubular shape as it is cylindrical and has at least two openings on the distal and proximal sides) and that accommodates the treatment tool main body 14 inside (see Figs. 1 and 4, [0045], 14 is inserted into an internal space 24 of 18) and has a through-hole 20 (see Figs. 1-6 and 8, [0043]) allowing fluid (see [0043], 20 is a water injection connector, hence water, a fluid, can be supplied inside) to be supplied inside, wherein the accommodating member 18 + 12 and the treatment tool main body 14 are configured to move relative to each other (see [0057], 16 can project and retract from the distal end 26 of 12, which with 18 forms the accommodating member) in the first direction distal direction so as to form a first state (see [0057], when 16 projects from distal end 26 of 12) in which the treatment tool main body 14 protrudes from a first opening the opening of 12 at 26 (see Fig. 1, [0057]) provided on a distal end side 26 (see Fig. 1, [0057]) of the accommodating member 18 + 12 and a second state (see [0057], when 16 is retracted from the distal end 26 of 12) in which the treatment tool main body 14 is retracted toward the proximal end side proximal side of 14 with respect to the first opening the opening of 12 at 26, wherein a distal end fitting portion 42 (see Fig. 4, [0051]) of the operation member 22 is inserted into an internal space 24 (see Fig. 4, [0046]) of the accommodating member 18, and the accommodating member 18 is configured to be slidable (see Fig. 4, [0069], can be inserted into 18 and that 18 can be slidable along 42 via rotation, the definition of slide according to the online Merriam Webster dictionary being “the move smoothly along a surface” which proximal and distal rotation of 18 to connect onto 22 is occurring smoothly) along the distal end fitting portion 42 of the operation member 22 toward the distal end side 26 and the proximal end side proximal side of 14, and the endoscopic treatment tool is configured such that: the first state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the proximal end side, and the second state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the distal end side. The language, " are formed by movement of the accommodating member," constitutes functional claim language, indicating that the claimed device need only be capable of being used in such a manner. The claim, however, is an apparatus claim, and is to be limited by structural limitations. The Office submits that the device of Ishikawa meets the structural limitations of the claim, and is capable of having the accommodating member 18 which is connected to the outer sheath 12 to control whether or not 16 is protruding from 12, by distally moving 18, this covers 16 and prevents it from being exposed, but while 18 is moved proximally and attached onto 42, 16 can be exposed as shown in Fig. 1. The language, "the endoscopic treatment tool is configured such that: the first state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the proximal end side, and the second state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the distal end side," constitutes functional claim language, indicating that the claimed device need only be capable of being used in such a manner. The claim, however, is an apparatus claim, and is to be limited by structural limitations. The Office submits that the device of Ishikawa meets the structural limitations of the claim, and is capable of the first state being formed with the treatment tool 14 of being protruded while the accommodating member 18 is towards the proximal side towards 22 as when the length of 16 is held and 18 is retracted proximally (which is attached to the tube 12) this will cause more of 16 to come out from 26, and the reverse is held true when 18 is advanced distally away from 22, thus pushing 12 distally as well to cover 16 + 14. Ishikawa does not explicitly disclose: the second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening; the distal end part is configured to be opened and closed and the operation member is used for an opening and closing operation of the distal end part. However, Motai in a similar field of invention teaches an endoscopic treatment tool 1 (see Figs. 1 and 12-13) with an operation member 65 (see Fig. 1); an accommodating member 10 (see Figs. 12-13) with a first opening the distal opening of 10 (see Figs. 12-13, [0069]) that accommodates a treatment tool 60 (see Figs. 1 and 12-13) with a treatment tool main body 61 (see Fig. 1) and a distal end part 170 (see Figs. 1 and 12-13). Motai further teaches: in the second state (see Fig. 13) in which the treatment tool main body 170 is entirely retracted toward the proximal end side (see Fig. 13, [0069], the entirety of 170 moves inside the second lumen 30 of 10, towards the proximal end side) with respect to the first opening the distal opening of 10 (see Fig. 13); the distal end part 170 is configured to be opened and closed (see Figs. 12-13, [0066]-[0067], the pair of jaws 171, 172 which comprise 170 open and close) and the operation member 65 is used for an opening and closing operation of the distal end part 170 (see [0067], the operation wire 175 which is connected to the operation member 65 is used to open and close 171 and 172). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ishikawa to incorporate the teachings of Motai and teach an endoscopic treatment tool with the distal end part of the treatment tool main body is configured to be opened and closed and the operation member is used for an opening and closing operation of the distal end part. Motivation for such can be found in Motai as this tool can be used to grasp and retrieve necrotic tissue (see [0069]). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ishikawa to incorporate the teachings of Motai and teach an endoscopic treatment tool with the second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. Motivation for such can be found in Motai as this allows the device to form a closed space (see [0069]) and thus preventing leakage of necrotic tissues which are grasped (see [0074]). Claim 2 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 1, see 103 rejection above. Ishikawa further discloses: wherein a position the relative position of 14 of the treatment tool main body 14 with respect to the operation member 22 is fixed (see [0057], when 22 is actuated this then moves 14, hence the position of 14 is fixed relative to 22), and the accommodating member 18 is configured to move in the first direction distal direction (see Fig. 4, [0051], 18 can be moved distally via rotation off of 42) with respect to the operation member 22. Claim 3 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 2, see 103 rejection above. Ishikawa further discloses: wherein the accommodating member 18 is slidably coupled (see [0070], there is slidable contact between 62, which is part of 18, and 64, which is part of 22 via 42 and this sliding action is part of the coupling between 18 and 22) to the operation member 22. Claim 4 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 3, see 103 rejection above. Ishikawa further discloses: wherein the accommodating member 18 is attachable to and detachable (see Fig. 4, [0051] and [0070], 18 can be disengaged from 22 via off of 42 with rotating and sliding action) from the operation member 22. Claim 6 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 1, see 103 rejection above. Ishikawa further discloses: further comprising: a first restricting portion 62 (see Figs. 1-6, [0059]) that restricts a distal end the distal end of 14 (see Figs. 1-6) of the treatment tool main body 14 from moving a predetermined distance or more (while 62 is preventing the rotation of 18, 18 is connected to 22, hence, 52 which controls how far 14 retracts proximally, is limited, unless 18 is disengaged and removed off, which then 14 can be taken out of 12, hence moving further proximally) toward the proximal end side the proximal side of 14 with respect to an opening edge the opening edge of 12 at 26 (see Fig. 1) of the first opening the opening of 12 at 26. Claim 7 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 6, see 103 rejection above. Ishikawa further discloses: wherein the first restricting portion 62 is provided at the accommodating member 18 (see Fig. 4, 62 is on 18). Claim 8 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 7, see 103 rejection above. Ishikawa further discloses: wherein the first restricting portion 62 is provided at a proximal end part 18a (see Fig. 4, [0052], 62 is on the proximal end part of 18) of the accommodating member 18. Claim 10 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 1, see 103 rejection above. Ishikawa further discloses: further comprising: a sealing member 44 (see Fig. 4, [0051]) provided between an inner peripheral surface inner surface of 24 (see Fig. 4, [0045]) of the accommodating member 18 on the proximal end side 18a (see Fig. 4, [0052]) and an outer peripheral surface the outer surface of 14 (see Fig. 4, 44 fits between the inner surface of 18 defined by 24 and the 14) of the treatment tool main body 14. Claim 11 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 10, see 103 rejection above. Ishikawa further discloses: wherein the sealing member 44 is provided on the proximal end side 18a with respect to the through-hole 20 (see Fig. 4, 44 is proximal compared to 20). Claim 13 The combination of Ishikawa and Motai teaches: The endoscopic treatment tool according to claim 1, see 103 rejection above. Motai further teaches: wherein the operation member 65 includes a main body part 66 (see Fig. 1, [0042]) and an operation element 67 (see Fig. 1, [0042]) supported by the main body part 66 so as to be movable in the first direction (see [0042], 67 is slidable on 66 distally), and the distal end part 170 of the treatment tool main body 61 is openable and closable in response to movement of the operation element 67 (see [0067], the operation wire 175 which is connected to the operation member 65 is used to open and close 171 and 172). Claim 14 Ishikawa discloses: An endoscopic treatment tool 10 (see Figs. 1-6 and 8, [0041]-[0042]) comprising: a treatment tool main body 14 (see Figs. 1 and 4, [0043]) that extends in a first direction the distal direction (see Figs. 1 and 4, 14 extends in a distal direction); an operation member 22 (see Figs. 1-5, [0043]) that is provided on a proximal end side proximal side of 14 (see Fig. 4, [0045]) of the treatment tool main body 14 and is used for operating (see [0057]) the treatment tool main body 14; and an accommodating member 18 + 12 (see Figs. 1-6 and 8, [0043] and [0046]) that has a tubular shape (see Figs. 1-6 and 8, 18 has a generally tubular shape as it is cylindrical and has at least two openings on the distal and proximal sides) and that accommodates the treatment tool main body 14 inside (see Figs. 1 and 4, [0045], 14 is inserted into an internal space 24 of 18) and has a through-hole 20 (see Figs. 1-6 and 8, [0043]) allowing fluid (see [0043], 20 is a water injection connector, hence water, a fluid, can be supplied inside) to be supplied inside, wherein a position the relative position of 14 of the treatment tool main body 14 with respect to the operation member 22 is fixed (see [0057], when 22 is actuated this then moves 14, hence the position of 14 is fixed relative to 22), and the accommodating member 18 is configured to move in the first direction distal direction (see Fig. 4, [0051], 18 can be moved distally via rotation off of 42), a first state (see [0057], when 16 projects from distal end 26 of 12) in which the treatment tool main body 14 protrudes from a first opening the opening of 12 at 26 (see Fig. 1, [0057]) of the accommodating member 18 on a distal end side 26 (see Fig. 1, [0057]) and a second state (see [0057], when 16 is retracted from the distal end 26 of 12) in which the treatment tool main body 14 is retracted toward the proximal end side proximal side of 14 with respect to the first opening the opening of 12 at 26 are formed by movement of the accommodating member, wherein a distal end fitting portion 42 (see Fig. 4, [0051]) of the operation member 22 is inserted into an internal space 24 (see Fig. 4, [0046]) of the accommodating member 18, and the accommodating member 18 is configured to be slidable (see Fig. 4, [0069], can be inserted into 18 and that 18 can be slidable along 42 via rotation, the definition of slide according to the online Merriam Webster dictionary being “the move smoothly along a surface” which proximal and distal rotation of 18 to connect onto 22 is occurring smoothly) along the distal end fitting portion 42 of the operation member 22 toward the distal end side 26 and the proximal end side proximal side of 14, and the endoscopic treatment tool is configured such that: the first state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the proximal end side, and the second state is formed in response to the accommodating member is slid on the distal end fitting portion of the operation member toward the distal end side. The language, " are formed by movement of the accommodating member," constitutes functional claim language, indicating that the claimed device need only be capable of being used in such a manner. The claim, however, is an apparatus claim, and is to be limited by structural limitations. The Office submits that the device of Ishikawa meets the structural limitations of the claim, and is capable of having the accommodating member 18 which is connected to the outer sheath 12 to control whether or not 16 is protruding from 12, by distally moving 18, this covers 16 and prevents it from being exposed, but while 18 is moved proximally and attached onto 42, 16 can be exposed as shown in Fig. 1. The language, "the endoscopic treatment tool is configured such that: the first state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the proximal end side, and the second state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the distal end side," constitutes functional claim language, indicating that the claimed device need only be capable of being used in such a manner. The claim, however, is an apparatus claim, and is to be limited by structural limitations. The Office submits that the device of Ishikawa meets the structural limitations of the claim, and is capable of the first state being formed with the treatment tool 14 of being protruded while the accommodating member 18 is towards the proximal side towards 22 as when the length of 16 is held and 18 is retracted proximally (which is attached to the tube 12) this will cause more of 16 to come out from 26, and the reverse is held true when 18 is advanced distally away from 22, thus pushing 12 distally as well to cover 16 + 14. Ishikawa does not explicitly disclose: the second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. However, Motai in a similar field of invention teaches an endoscopic treatment tool 1 (see Figs. 1 and 12-13) with an operation member 65 (see Fig. 1); an accommodating member 10 (see Figs. 12-13) with a first opening the distal opening of 10 (see Figs. 12-13, [0069]) that accommodates a treatment tool 60 (see Figs. 1 and 12-13) with a treatment tool main body 61 (see Fig. 1) and a distal end part 170 (see Figs. 1 and 12-13). Motai further teaches: in the second state (see Fig. 13) in which the treatment tool main body 170 is entirely retracted toward the proximal end side (see Fig. 13, [0069], the entirety of 170 moves inside the second lumen 30 of 10, towards the proximal end side) with respect to the first opening the distal opening of 10 (see Fig. 13). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ishikawa to incorporate the teachings of Motai and teach an endoscopic treatment tool with the second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. Motivation for such can be found in Motai as this allows the device to form a closed space (see [0069]) and thus preventing leakage of necrotic tissues which are grasped (see [0074]). Claim 15 Ishikawa discloses: An endoscopic treatment tool 10 (see Figs. 1-6 and 8, [0041]-[0042]) comprising: a treatment tool main body 14 (see Figs. 1 and 4, [0043]) that extends in a first direction the distal direction (see Figs. 1 and 4, 14 extends in a distal direction); an operation member 22 (see Figs. 1-5, [0043]) that is provided on a proximal end side proximal side of 14 (see Fig. 4, [0045]) of the treatment tool main body 14 and is used for operating (see [0057]) the treatment tool main body 14; and an accommodating member 18 + 12 (see Figs. 1-6 and 8, [0043] and [0046]) that has a tubular shape (see Figs. 1-6 and 8, 18 has a generally tubular shape as it is cylindrical and has at least two openings on the distal and proximal sides) and that accommodates the treatment tool main body 14 inside (see Figs. 1 and 4, [0045], 14 is inserted into an internal space 24 of 18) and has a through-hole 20 (see Figs. 1-6 and 8, [0043]) allowing fluid (see [0043], 20 is a water injection connector, hence water, a fluid, can be supplied inside) to be supplied inside, wherein the accommodating member 18 + 12 and the treatment tool main body 14 are configured to move relative to each other (see [0057], 16 can project and retract from the distal end 26 of 12, which with 18 forms the accommodating member) in the first direction distal direction so as to form a first state (see [0057], when 16 projects from distal end 26 of 12) in which the treatment tool main body 14 protrudes from a first opening the opening of 12 at 26 (see Fig. 1, [0057]) provided on a distal end side 26 (see Fig. 1, [0057]) of the accommodating member 18 + 12 and a second state (see [0057], when 16 is retracted from the distal end 26 of 12) in which the treatment tool main body 14 is retracted toward the proximal end side proximal side of 14 with respect to the first opening the opening of 12 at 26 and the endoscopic treatment tool 10 further comprises a first restricting portion 62 (see Figs. 1-6, [0059]) that restricts a distal end the distal end of 14 (see Figs. 1-6) of the treatment tool main body 14 from moving a predetermined distance or more (while 62 is preventing the rotation of 18, 18 is connected to 22, hence, 52 which controls how far 14 retracts proximally, is limited, unless 18 is disengaged and removed off, which then 14 can be taken out of 12, hence moving further proximally) toward the proximal end side the proximal side of 14 with respect to an opening edge the opening edge of 12 at 26 (see Fig. 1) of the first opening the opening of 12 at 26, wherein a distal end fitting portion 42 (see Fig. 4, [0051]) of the operation member 22 is inserted into an internal space 24 (see Fig. 4, [0046]) of the accommodating member 18, and the accommodating member 18 is configured to be slidable (see Fig. 4, [0069], can be inserted into 18 and that 18 can be slidable along 42 via rotation, the definition of slide according to the online Merriam Webster dictionary being “the move smoothly along a surface” which proximal and distal rotation of 18 to connect onto 22 is occurring smoothly) along the distal end fitting portion 42 of the operation member 22 toward the distal end side 26 and the proximal end side proximal side of 14, and the endoscopic treatment tool is configured such that: the first state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the proximal end side, and the second state is formed in response to the accommodating member is slid on the distal end fitting portion of the operation member toward the distal end side. The language, " are formed by movement of the accommodating member," constitutes functional claim language, indicating that the claimed device need only be capable of being used in such a manner. The claim, however, is an apparatus claim, and is to be limited by structural limitations. The Office submits that the device of Ishikawa meets the structural limitations of the claim, and is capable of having the accommodating member 18 which is connected to the outer sheath 12 to control whether or not 16 is protruding from 12, by distally moving 18, this covers 16 and prevents it from being exposed, but while 18 is moved proximally and attached onto 42, 16 can be exposed as shown in Fig. 1. The language, "the endoscopic treatment tool is configured such that: the first state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the proximal end side, and the second state is formed in response to the accommodating member being slid on the distal end fitting portion of the operation member toward the distal end side," constitutes functional claim language, indicating that the claimed device need only be capable of being used in such a manner. The claim, however, is an apparatus claim, and is to be limited by structural limitations. The Office submits that the device of Ishikawa meets the structural limitations of the claim, and is capable of the first state being formed with the treatment tool 14 of being protruded while the accommodating member 18 is towards the proximal side towards 22 as when the length of 16 is held and 18 is retracted proximally (which is attached to the tube 12) this will cause more of 16 to come out from 26, and the reverse is held true when 18 is advanced distally away from 22, thus pushing 12 distally as well to cover 16 + 14. Ishikawa does not explicitly disclose: the second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. However, Motai in a similar field of invention teaches an endoscopic treatment tool 1 (see Figs. 1 and 12-13) with an operation member 65 (see Fig. 1); an accommodating member 10 (see Figs. 12-13) with a first opening the distal opening of 10 (see Figs. 12-13, [0069]) that accommodates a treatment tool 60 (see Figs. 1 and 12-13) with a treatment tool main body 61 (see Fig. 1) and a distal end part 170 (see Figs. 1 and 12-13). Motai further teaches: in the second state (see Fig. 13) in which the treatment tool main body 170 is entirely retracted toward the proximal end side (see Fig. 13, [0069], the entirety of 170 moves inside the second lumen 30 of 10, towards the proximal end side) with respect to the first opening the distal opening of 10 (see Fig. 13). It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Ishikawa to incorporate the teachings of Motai and teach an endoscopic treatment tool with the second state in which the treatment tool main body is entirely retracted toward the proximal end side with respect to the first opening. Motivation for such can be found in Motai as this allows the device to form a closed space (see [0069]) and thus preventing leakage of necrotic tissues which are grasped (see [0074]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Kawamoto et al (US 20220304553 A1) teaches an endoscopic tool with a treatment tool that slides entirely in and out of a distal opening of an oversheath 26 (see Figs. 6-7) Any inquiry concerning this communication or earlier communications from the examiner should be directed to RAIHAN R KHANDKER whose telephone number is (571)272-6174.
