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. Claim(s) 1-8, 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cabiri (US. 20160310702A1) in view of Kondo et al. (US. 20080255423A1) (“Kondo”). Re Claim 1, Cabiri discloses a steerable cannula (Fig. 1-8) for a transjugular intrahepatic portosystemic shunt ("TIPS") procedure ( it is capable to be used in medical filed such as TIPS procedure, ¶0003, ¶0034, ¶0042), comprising: an elongate compound tube (14, 12) having a proximal-end portion (close to 13, Fug. 3) and a distal-end portion (close to 67, Fig. 6c), the distal-end portion including a flexible hinge (alive flexible hinges between slots, Fig. 5a-7b, opposite to the slot 16) for adjusting a cannula angle between the proximal-end portion and the distal-end portion of the compound tube adjacent the flexible hinge (Fig. 5a-7b, ¶0028, ¶0031); a lumen of the compound tube (lumen of 12, Fig. 6d) wherein a distal end of each of an inner tube (a portion of 12 at 67 ) and an outer tube of the compound tube (a portion of 14 close to 67) is fixedly attached (¶0045, at 67); and a compound hub (202, 228, 204, 206) disposed about the proximal-end portion of the compound tube (Fig. 5d); and an articulation mechanism (220, 222, ¶0042) controlled by at least a rotatable element (222) of the compound hub for adjusting the cannula angle (¶0042), the articulation mechanism configured to longitudinally move the inner tube (12) of the compound tube relative to the outer tube of the compound tube to adjust the cannula angle (14, Fig. 7a-b, ¶0042), but it fails to disclose that the cannula comprises a cannula tip coupled to a distal end of the compound tube, the cannula tip including a tip opening fluidly connected to the lumen of the compound tube and distal end of each inner tune and outer tube are fixedly connected to the cannula tip. However, Kondo discloses a compound tube (10, Figs. 1-6) and wherein comprises a cannula tip (20) fixedly attached to each distal end of the inner tube (distal end of 16, ¶0063) and outer tube (13, 12) of the compound tube ( Fig. 4, ¶0063). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify canula of Cabiri to include a canula tip so that the cannula comprises a cannula tip coupled to a distal end of the compound tube, the cannula tip including a tip opening fluidly connected to the lumen of the compound tube and distal end of each inner tune and outer tube are fixedly connected to the cannula tip as taught by Kondo for the purpose of performing bending operation and to smoothly guiding the insertion tools within the lumen (Kondo,¶0063, ¶0078). Re Claim 2, Cabiri discloses wherein each tube of the inner tube and the outer tube of the compound tube includes a set of transverse cutouts (16 of 14, 16 on 12, Fig. 7b), the flexible hinge of the compound tube formed between offset sets of the transverse cutouts in at least a non-deflected state of the compound tube, Fig. 7a, ¶0032). Re Claim 3, Cabiri discloses wherein the rotatable element of the compound hub is a rotatable handle (220, ¶0042) configured to rotate relative to a housing of the compound hub (202, ¶0042), the rotatable handle including a threaded bore (¶0042, 222 has a thread) or an insert including a threaded bore configured to drive a threaded plug (218 proximally when the rotatable handle is rotated in a first direction ( backward, ¶0041, ¶0042) or distally when the rotatable handle is rotated in a second direction ( forward, ¶0041, ¶0042). Re Claim 4, Cabiri discloses wherein the threaded plug is fixedly attached to the inner tube of the compound tube (¶0042) such that the inner tube is driven proximally or distally in concert with the threaded plug when the rotatable handle is respectively rotated in the first direction or the second direction (¶0041, ¶00242). Re Claim 5, Cabiri discloses wherein the outer tube of the compound tube is fixedly attached to a stationary element disposed in the housing of the compound hub (204, ¶0041), the inner tube of the compound tube passing through the stationary element (¶0041). Re Claim 6, Cabiri discloses that the inner tube is longitudinally moved relative to the outer tube when the rotatable handle of the compound hub is rotated in the first direction or the second direction (¶0041, ¶0042). Re Claim 7, Cabiri discloses wherein the lumen of the compound tube extends longitudinally through the compound tube (Fig. 6d, ¶0038) and is configured for disposing a needle or a catheter-and-needle assembly therein (¶0038, catheter and/other devices). Re Claim 8, Cabiri discloses wherein the cannula angle ranges from about -90 degree to about 90 degree (Fig, 7a-7b, ¶0028). Re Claim 10, Cabiri discloses wherein the steerable cannula is configured to stiffen a catheter assembly in support of a needle throw from the catheter assembly at the cannula angle chosen for the needle throw ( it is capable to stiffens the catheter 18, ¶0034). Claim(s) 21-29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cabiri (US. 20160310702A1) in view of Rottenberg et al. (US. 20120235229A1) (“Rottenberg”) and further in view of Kondo et al. (US. 20080255423A1) (“Kondo”). Re Claim 21, Cabiri discloses an access set (Fig. 1-8) for a transjugular intrahepatic portosystemic shunt ("TIPS") procedure (it is capable to be used in medical filed such as TIPS procedure, ¶0003, ¶0034, ¶0042), comprising: an introducer sheath (18, ¶0034, Fig. 2);a piercing device (¶0038, catheter or other device); and a stiffening cannula (10, ¶0034) selected from a steerable cannula (¶0034) and a fixed-curve cannula configured to support a piercing-device throw from the stiffening cannula (it is capable to guide a catheter or needle, ¶0038), the steerable cannula including an articulation mechanism (220, 222, ¶0042) configured to longitudinally move an inner tube (12) of an elongate compound tube relative to an outer tube (14) of the compound tube to adjust the piercing-device angle for the piercing-device throw (Fig. 7a-c, ¶0042); but it fails to disclose that the piercing device selected from a hinged needle, a Colapinto needle, and a trocar stylet, the hinged needle including an elongate needle tube having a flexible hinge and a pencil-point needle tip coupled to a distal end of the needle tube having a tip opening fluidly connected to a lumen of the needle tube and a distal end of each tube of the inner tune and the outer tube of the coonhound tube is fixedly attached to the cannula tip. However, Rottenberg discloses a hinged needle (Figs. 1-8) for a transjugular intrahepatic portosystemic shunt ("TIPS") procedure ( it is capable to be used in TIPS ¶0029), comprising: a piercing device selected from a hinged needle, a Colapinto needle, and a trocar stylet (hinged needle, 10) having a proximal-end portion ( lower half portion of 10, Fig. 8) and a distal-end portion ( upper portion of 10, Fig. 8), the distal-end portion including a flexible hinge ( live hinge between the cut 23, Fig. 5, ¶0037) and a pencil-point needle tip (15) coupled to a distal end of the needle tube (Fig. 8), the needle tip including a tip opening fluidly connected to a lumen of the needle tube (16, ¶0045, ¶0030), and further discloses that proximal portion of the tube is connected with luer connector (¶0046). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify canula of Cabiri so that the piercing device selected from a hinged needle, a Colapinto needle, and a trocar stylet, the hinged needle including an elongate needle tube having a flexible hinge and a pencil-point needle tip coupled to a distal end of the needle tube having a tip opening fluidly connected to a lumen of the needle tube as taught by Rottenberg for the purpose of using the needle for penetration tissue (Rottenberg, ¶0011). The amended Cabiri in view of Rottenberg fails to disclose a distal end of each tube of the inner tune and the outer tube of the coonhound tube is fixedly attached to the cannula tip. However, Kondo discloses a compound tube (10, Figs. 1-6) and wherein comprises a cannula tip (20) fixedly attached to each distal end of the inner tube (distal end of 16, ¶0063) and outer tube (13, 12) of the compound tube ( Fig. 4, ¶0063). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify canula of Cabiri to include a canula tip so that a distal end of each tube of the inner tune and the outer tube of the coonhound tube is fixedly attached to the cannula tip as taught by Kondo for the purpose of performing bending operation and to smoothly guiding the insertion tools within the lumen (Kondo,¶0063, ¶0078). Re Claim 22, Cabiri discloses wherein each tube of the inner tube and the outer tube of the compound tube of the steerable cannula includes a set of transverse cutouts (16 of 14 and 16 of 12, Fig. 7a-c) forming a flexible hinge of the compound tube, each set of transverse cutouts offset from the other in at least a non-deflected state of the compound tube (Fig, 7a, ¶0031). Re Claim 23, Cabiri discloses wherein a rotatable handle (220) of a compound hub of the steerable cannula (220, 202, 228, 204, 206, ¶0042) configured to rotate relative to a housing of the compound hub (202, ¶0042), the rotatable handle including a threaded bore (¶0042, 222 has a thread) or an insert including a threaded bore configured to drive a threaded plug (218 proximally when the rotatable handle is rotated in a first direction (backward, ¶0041, ¶0042) or distally when the rotatable handle is rotated in a second direction (forward, ¶0041, ¶0042). Re Claim 24, Cabiri discloses wherein the threaded plug is fixedly attached to the inner tube of the compound tube (¶0042) such that the inner tube is driven proximally or distally in concert with the threaded plug when the rotatable handle is respectively rotated in the first direction or the second direction (¶0041, ¶00242). Re Claim 25, Cabiri discloses wherein the outer tube of the compound tube is fixedly attached to a stationary element disposed in the housing of the compound hub (204, ¶0041), the inner tube of the compound tube passing through the stationary element (¶0041). Re Claim 26, Cabiri discloses that the inner tube is longitudinally moved relative to the outer tube when the rotatable handle of the compound hub is rotated in the first direction or the second direction (¶0041, ¶0042). Re Claim 27, Cabiri fails to disclose wherein an entirety of the needle tube of the hinged needle is a metal hypotube, the flexible hinge selected from a spiral-cut portion of the hypotube, a slotted portion of the hypotube, and a nitinol portion of the hypotube. However, Rottenberg discloses an entirety of the needle tube of the hinged needle is a metal hypotube (¶0015. ¶0035), the flexible hinge selected from a spiral-cut portion of the hypotube, a slotted portion of the hypotube, and a nitinol portion of the hypotube (¶0015, 035 ¶0035). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify canula of Cabiri to include a needle so that an entirety of the needle tube of the hinged needle is a metal hypotube, the flexible hinge selected from a spiral-cut portion of the hypotube, a slotted portion of the hypotube, and a nitinol portion of the hypotube as taught by Rottenberg for the purpose of using the a needle for penetration tissue form desired material (Rottenberg, ¶0011¶0015, ¶0035). Re Claim 28, the modified Cabiri discloses wherein the needle tube of the hinged needle is a hypotube coupled to a spring or braided tube as the flexible hinge (¶0015, spring of . Rottenberg) Re Claim 29, the modified Cabiri discloses wherein the tip opening of the needle tip of the hinged needle is distal to where the needle tip is coupled to the distal end of the needle tube (16, Fig. 8 of Rottenberg). Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cabiri in view of Kondo and further in view of Hebert et al. (US. 20060004329A1) (“Hebert”).
