Office Action

§103
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 . This office action is in response to applicant’s communication of 09/02/2026. Currently claims 1-7, 9-17, and 19-20 are pending and rejected below. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 1-7, 9-17, and 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gunderson et al. (US 2014/0074022 A1) in view of Bazell et al. (US 3,884,242). Gunderson discloses a removable loading tool and protector for a medical device (as in figures 8-14), comprising: a body (210) having a generally tubular configuration and comprising a proximal end (214), a distal end (212), an intermediate region (242) disposed between the proximal end and the distal end, and a lumen disposed therethrough; and a proximal region having a length and extending from the proximal end of the body, the proximal region comprising at least one slit (244) positioned adjacent to the proximal end of the body; wherein the proximal region has a first inner diameter and the intermediate region has a second inner diameter, the first inner diameter of the proximal region being greater than the second inner diameter of the intermediate region (see figures 10). Concerning the claim language of and “the distal end has a beveled configuration having an angle with respect to a longitudinal axis (see 240 portion). Examiner is of the position that this is a sloping edge or angled edge (with respect to the longitudinal axis. Although the prior art states this to be a “flared” portion this does not prevent the sloping angled edge to be considered a “beveled configuration”. Applicant has not provided a “special definition” of the term “beveled”. Examiner is of the position that the distal end portion near 240 of Gunderson would teach and anticipated a “beveled configuration”. Gunderson discloses the claimed invention except for the distal end bevel having an angle to define a leading edge. Bazell teaches that it is known to use the distal end bevel having an angle to define a leading edge as set forth in paragraphs at column 1 lines 5-30,column 4 lines 63-68, column 8 lines 5-65 and figures 1-15 for example, and edges 19, 25, 31, 71 for examples such as to provide [motivational statement]. It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the system as taught by Gunderson with the distal end bevel having an angle to define a leading edge as taught by Bazell, since such a modification would provide the system with the distal end bevel having an angle to define a leading edge for providing a chamfered edge or tapered collar bevel and way to reduce tissue lesions upon insertion or removal, for fitting or sealing the tip to the body portion of the tube PNG media_image1.png 222 489 media_image1.png Greyscale Concerning claim 2 and the first inner diameter of the proximal region is uniform throughout its length (See figure 10 interior diameter). Concerning claim 3 and the first inner diameter of the proximal region varies throughout its length (see figure 14). Concerning claim 4 and the proximal region comprises a first section having an inner diameter and a tapered second section, the tapered second section positioned distal to the uniform first section (see figure 11). Concerning claim 5 and the inner diameter of the first section of the proximal region is equal to the first inner diameter of the proximal region and is uniform throughout its length (see figure 10 for example). Concerning claim 6 and the tapered second section forms an angle of 45 degrees or less with respect to a longitudinal axis of the body (see figures 10 angle and also para [0047]). Concerning claim 7 and the tapered second section forms an angle of 30 degrees with respect to a longitudinal axis of the body (see figures 10 angle and also para [0047]). Concerning claim 9 and the angle of the beveled configuration of the distal end ranges from 10 to 90 degrees (see figures 10 angle and also para [0047]). Concerning claim 10 and a rib is disposed about an outer surface of the body proximate to the distal end (see 218). Concerning claim 11 and the slit has a length and the length of the slit is less than the length of the proximal region (see figures 8). Concerning claim 12 and a medical device assembly comprising: a catheter having a proximal end, a distal end, and a lumen therethrough; a drug coated expandable medical device disposed about a distal portion of the catheter (see para [0007]), the expandable medical device having a distal end and a proximal end; and a loading tool and protector removably disposed about the catheter and the medical device, the loading tool and protector comprising, a body having a generally tubular configuration and comprising a proximal end, a distal end, an intermediate region disposed between the proximal end and the distal end, and a lumen disposed therethrough; and a proximal region having a length and extending from the proximal end of the body, the proximal region comprising at least one slit positioned adjacent to the proximal end of the body; wherein the proximal region has a first inner diameter and the intermediate region has a second inner diameter, the first inner diameter of the proximal region being greater than the second inner diameter of the intermediate region (see previously identified structures and also figures 8-14). Concerning the claim language of and “the distal end has a beveled configuration having an angle with respect to a longitudinal axis (see 240 portion). Examiner is of the position that this is a sloping edge or angled edge (with respect to the longitudinal axis. Although the prior art states this to be a “flared” portion this does not prevent the sloping angled edge to be considered a “beveled configuration”.

Concerning claim 14 and the first inner diameter of the proximal region of the loading tool and protector is uniform throughout its length (See figure 10 interior diameter). Concerning claim 15 and the first inner diameter of the proximal region of the loading tool and protector varies throughout its length (see figure 14). Concerning claim 16 and the proximal region of the loading tool and protector comprises a first section having an inner diameter and a tapered second section, the tapered second section positioned distal to the uniform first section (see figures 10 device). Concerning claim 17 and the tapered region of the proximal region of the loading tool and protector forms an angle of 45 degrees or less with respect to a longitudinal axis of the body (see figures 10 angle and also para [0047]). Concerning claim 19 and a rib is disposed about an outer surface of the body of the loading tool and protector proximate to the distal end (see 218). Concerning claim 20 and a medical device assembly comprising: a catheter having a proximal end, a distal end, and a lumen therethrough; a drug coated expandable balloon disposed about a distal portion of the catheter (para 0007]), the expandable balloon having a distal end and a proximal end; and a loading tool and protector removably disposed about the catheter and the expandable balloon, the loading tool and protector comprising, a body having a generally tubular configuration and comprising a proximal end, a beveled distal end, an intermediate region disposed between the proximal end and the distal end, and a lumen disposed therethrough; and a proximal region having a length and extending from the proximal end of the body, the proximal region comprising a first section, a tapered second section, and at least one slit positioned adjacent to the proximal end of the body and within the first section, the slit having a length; and wherein the first section of the proximal region has a first inner diameter and the intermediate region has a second inner diameter, the first inner diameter of the first section of the proximal region being greater than the second inner diameter of the intermediate region, and wherein the length of the slit is less than the length of the proximal region (see discussion regarding the structures discussed above and further figures 8-14 for examples). Concerning the claim language of and “the distal end has a beveled configuration having an angle with respect to a longitudinal axis (see 240 portion). Examiner is of the position that this is a sloping edge or angled edge (with respect to the longitudinal axis. Although the prior art states this to be a “flared” portion this does not prevent the sloping angled edge to be considered a “beveled configuration”.

PNG media_image2.png 528 756 media_image2.png Greyscale Gunderson discloses the claimed invention except for the distal end bevel having an angle to define a leading edge. Bazell teaches that it is known to use the distal end bevel having an angle to define a leading edge as set forth in paragraphs at column 1 lines 5-30,column 4 lines 63-68, column 8 lines 5-65 and figures 1-15 for example, and edges 19, 25, 31, 71 for examples such as to provide [motivational statement].

Applicant argues that the prior art fails to teach a beveled configuration “…to define a leading edge…”. Examiner is of the position that the amended claim language is taught in the prior art Gunderson in view of Bazell. Particularly examiner is of the position that Bazell teaches forming tubular structures with beveled leading edges. Bazell, teaches such a modification of beveling an edge to provide the system a chamfered edge or tapered collar bevel and way to reduce tissue lesions upon insertion or removal, for fitting or sealing the tip to the body portion of the tube. Examiner is of the position that this would be an obvious modification to a PHOSITA to have the distal edge with a bevel and defining a leading edge in order to reduce tissue lesions upon insertion or removal, for fitting or sealing the tip to the body portion of the tube. The elements disclosed in Gunderson, Bazell, and any obvious modifications thereof are fully capable of satisfying all structural, functional, spatial, and operational limitations in the amended claims, as currently written, and the rejection is made.
