Abstract
Abstract Apparatus for implanting closable locking clips to effect the percutaneous occlusion of target vessels or tissue is disclosed, including a pair of pivotable jaws defining a clip retaining cavity, a clip moving slide for sliding a locking clip from a retracted position remote from the clip retaining cavity to an actuated position with the clip retaining cavity, and a camming surface operatively disposed within the clip retaining cavity so that upon slidable movement of the locking clip from the retracted position to the actuated position the camming surface causes at least partial closure of the locking clip therein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
Apparatus for implanting a closable clip to effect the occlusion of a target vessel or tissue, comprising first and second jaw members relatively movable between opened and closed positions, said first and second jaw members defining a clip-retaining cavity therebetween, said clip-retaining cavity having sufficient size to accommodate said clip therein, and clip closure means for moving said clip from a retractable position displaced from said clip-retaining cavity to an actuating position within said clip-retaining cavity, and for causing at least partial closure of said clip.
Claim 2
Dependent Claim
86 words
Apparatus for implanting a closable clip to effect the occlusion of a target vessel or tissue, comprising first and second jaw members relatively movable between opened and closed positions, said first and second jaw members defining a clip-retaining cavity therebetween, said clip-retaining cavity having sufficient size to accommodate said clip therein, and clip closure means for moving said clip from a retractable position displaced from said clip-retaining cavity to an actuating position within said clip-retaining cavity, and for causing at least partial closure of said clip.
Claim 3
Dependent Claim
24 words
The apparatus of claim 1 including camming means disposed within said clip-retaining cavity for assisting in said at least partial closure of said clip.
Claim 4
Dependent Claim
22 words
The apparatus of claim 2 wherein said camming means is associated with at least one of said first and second jaw members.
Claim 5
Dependent Claim
51 words
The apparatus of claim 3 wherein said one of said first and second jaw members includes an inner surface defining a portion of said clip-retaining cavity, and wherein said camming means comprises an angularly displaced wall surface of said inner surface of said one of said first and second jaw members.
Claim 6
Dependent Claim
33 words
The apparatus of claim 1 wherein said clip closure means comprises a slidable pusher member including a first end proximate to said clip-retaining cavity and a second end distal from said clip-retaining cavity.
Claim 7
Dependent Claim
83 words
The apparatus of claim 5 wherein said clip closure means includes pivotable handle means including a first end distal from said second end of said slidable pusher member and a second end proximate to said second end of said slidable pusher member and in contact therewith, said pivotable handle means being pivotable about a point intermediate of said first and second ends of said pivotable handle means whereby pivoting of said pivotable handle means results in longitudinal displacement of said slidable pusher member.
Claim 8
Dependent Claim
38 words
The apparatus of claim 6 wherein said slidable pusher member includes groove means substantially transverse to the direction defined by said longitudinal displacement of said slidable pusher member, and wherein said pivotable handle means includes groove follower means.
Claim 9
Dependent Claim
37 words
The apparatus of claim 1 wherein said first jaw member remains stationary and said second jaw member is pivotable, including second jaw member pivot means for pivoting said second jaw member between said open and closed positions.
Claim 10
Dependent Claim
17 words
The apparatus of claim 8 wherein said second jaw pivot means comprises a second jaw handle member.
Claim 11
Dependent Claim
21 words
The apparatus of claim 9 including second handle member locking means for locking said second handle member in said closed position.
Claim 12
Independent Claim
16 words
The apparatus of claim wherein said first and second jaw members define a smooth outer surface.
Claim 13
Dependent Claim
42 words
The apparatus of claim 11 wherein said first and second jaw members combine to define an opening at the distal end therebetween, said opening substantially duplicating the occlusion of said target vessel or tissue by said clip when said clip is closed.
