Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
An endoscopic apparatus for atraumatically engaging mammalian tissue, comprising: a frame having a proximal end and a distal end, said frame having a passage therethrough; a handle means mounted to the distal end of the frame for holding the apparatus; jaw means attached to the distal end of the instrument, moveable between a fully open position and a fully closed position; actuating means for moving the jaw means between fully extended and fully closed positions; and atraumatic means mounted to the jaw means effective to make the apparatus atraumatic when the jaw means are actuated.
Claim 2
Dependent Claim
95 words
An endoscopic apparatus for atraumatically engaging mammalian tissue, comprising: a frame having a proximal end and a distal end, said frame having a passage therethrough; a handle means mounted to the distal end of the frame for holding the apparatus; jaw means attached to the distal end of the instrument, moveable between a fully open position and a fully closed position; actuating means for moving the jaw means between fully extended and fully closed positions; and atraumatic means mounted to the jaw means effective to make the apparatus atraumatic when the jaw means are actuated.
Claim 3
Dependent Claim
71 words
The endoscopic apparatus of claim 1 wherein the actuating means comprises, a handle lever pivotally mounted to the proximal end of the frame; an elongated member housed within said frame and pivotally attached at the proximal end to the handle lever; and, connecting members pivotally mounted at one end to the distal end of the elongated member, and the other end of said connecting members being mounted to the jaw means.
Claim 4
Dependent Claim
41 words
The endoscopic apparatus of claim 1 or claim 2 wherein the jaw means comprises a pair of pivotally mounted, opposed longitudinal members having a distal end and a proximal end, said members having distal mounting means for receiving the atraumatic means.
Claim 5
Dependent Claim
12 words
The endoscopic apparatus of claim 3 wherein the longitudinal members are curved.
Claim 6
Dependent Claim
33 words
The endoscopic apparatus of claim 3 or claim 4 wherein the longitudinal members further comprise angulated lever arms projecting from the proximal end of each longitudinal member for pivotally mounting said connecting members.
Claim 7
Dependent Claim
52 words
The endoscopic apparatus of any of claims 3 to 5 wherein the atraumatic means comprise at least one pad member mounted to each distal mounting means, said pad having an inner surface for engaging tissue, a proximal surface for engaging tissue, and an outer surface for mounting to the distal mounting means.
Claim 8
Dependent Claim
20 words
The apparatus of claim 6 wherein the pad member further comprises a plurality of projections extending from the inner surface.
Claim 9
Dependent Claim
28 words
The apparatus of claim 6 or claim 7 wherein the pad member comprises at least one projection extending from the outer surface for mounting in the mounting means.
Claim 10
Dependent Claim
20 words
The endoscopic apparatus of any of claims 3 to 8 wherein the distal mounting means comprises a blunt distal end.
Claim 11
Dependent Claim
25 words
The endoscopic apparatus of any of claims 3 to 9 further comprising a gap between the longitudinal members when the jaw means are fully closed.
Claim 12
Dependent Claim
22 words
The endoscopic apparatus of any of claims 3 to 10 wherein the distal mounting means comprises at least one slot extending therethrough.
