Election/Restrictions
Applicant’s election without traverse of Group I, Species D, 3 in the replies filed on 12/9/2025 and 12/29/2025 is acknowledged. Claims 3-4, 6-12, 14-16 and 18 are withdrawn.
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) 1-2, 5, 13, and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Murphy et al. (US 2019/0254676) in view of Bagaoisan (US 2002/0177800). Murphy discloses a vaso-occlusive treatment system, comprising: a delivery assembly (104); and a vaso-occlusive device (106) detachably coupled to the delivery assembly by a delivery assembly junction (200; see fig. 51,52), the vaso-occlusive device comprising a braided portion (106) formed out of one or more wires, the braided portion comprising a packed end bundle (126; fig. 51 – packed into 320), a coiled portion (108) coupled to the braided portion, and an intra-device junction (300-1; fig. 51) coupling the braided portion to the coiled portion, the intra-device junction comprising a stretch-resistant member (122) spanning from the packed end bundle to the delivery assembly junction. Murphy does not expressly disclose that the packed end bundle (126) defines an end surface that is oblique to a longitudinal axis of the packed end bundle.
Bagaoisan in the same field of endeavor, namely surgical instruments for treatment of vasculature, teaches that the end surface (520) of a first tubular element (506) may be oblique relative to its longitudinal axis in order to facilitate insertion of the end of the first tubular element into the lumen of a second tubular element (516) (see [0122]; fig. 25). Since the packed end bundle (126; fig. 51) of Murphy, which comprises a tubular braid, is inserted into a marker band (320) (see figs. 51, 52), one skilled in the art would have found it obvious to have modified the prior art of Murphy to construct the packed end bundle (126) with an end surface that is oblique to a longitudinal axis of the packed end bundle in view of Bagaoisan for the predictable result of facilitating easier insertion of the packed end bundle into the marker band during manufacture.
Regarding claim 2, the stretch-resistant member comprises first and second ends (forming distal hooks 338; fig. 51, 52 and [0131]).
Regarding claim 5, the first and second ends (338) are each terminated within the braided portion (see figs. 51, 52).
Regarding claim 13, the system further comprises a second stretch-resistant member (noting paragraph [0134]; see also fig. 33 or figs. 57, 58), wherein the second stretch-resistant member comprises third and fourth ends (hooks 338, noting [0134] discloses that the distal stretch-resisting member may be anchored similar to 122 in figs. 51, 52; see also end attached to 120 and end attached to 316 in fig. 33).
Regarding claim 17, the packed end bundle (126 in figs. 51, 52) is a proximal end bundle, the coiled portion is a proximal coiled portion, the intra-device junction is a proximal intra-device junction, and the stretch-resistant member is a proximal stretch-resistant member (see figs. 51, 52). The braided portion further comprises a distal packed end bundle (128), wherein the system further comprises: a distal coiled portion (110) coupled to the distal packed end bundle; and a distal intra-device junction coupling the braided portion to the distal coiled portion, the distal intra-device junction comprising a distal stretch-resistant member spanning from the distal packed end bundle to a distal end of the distal coiled portion. In particular, paragraph [0134] states that, while not shown in figs. 51 and 52, the distal end of the vaso-occlusive coil 102 may include a coiled distal portion, with a distal intra-device junction having a distal stretch-resisting member anchored similarly to the stretch resisting member 122 depicted in figs. 51, 52 (similar to fig. 58, the device comprises a proximal stretch-resistant member and a distal stretch-resistant member).
