Abstract
Abstract An improved endoscopic device of the type having a surgical needle; a hollow tube; and a filamentary strand attached at its distal end to the surgical needle, and slideably engaged at its proximal end about the tube with a partially tightened slip knot. The improvement in the device relates to means for pulling the filamentary strand through the hollow tube proximally when the surgical needle is detached from the strand. The device can be used to approximate tissue or ligate a vessel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
An improved endoscopic device of the type having a surgical needle; a hollow tube; and a filamentary strand attached at its distal end to the surgical needle, and slidable engaged at its proximal end about said tube with a partially tightened slip knot; wherein the improvement comprises means for pulling the filamentary strand through the hollow tube proximally when the surgical needle is detached from the strand, wherein said means for pulling comprises: a) a wire-like member extending through said hollow tube, said wire-like member attached at its proximal end to the proximal end of said hollow tube, and said wire-like member having a deformable distal loop thereon for receiving at least a portion of said filamentary strand, said deformable distal loop protruding from the distal end of said hollow tube; and b) a frangible proximal end portion on said hollow tube.
Claim 2
Dependent Claim
142 words
An improved endoscopic device of the type having a surgical needle; a hollow tube; and a filamentary strand attached at its distal end to the surgical needle, and slidable engaged at its proximal end about said tube with a partially tightened slip knot; wherein the improvement comprises means for pulling the filamentary strand through the hollow tube proximally when the surgical needle is detached from the strand, wherein said means for pulling comprises: a) a wire-like member extending through said hollow tube, said wire-like member attached at its proximal end to the proximal end of said hollow tube, and said wire-like member having a deformable distal loop thereon for receiving at least a portion of said filamentary strand, said deformable distal loop protruding from the distal end of said hollow tube; and b) a frangible proximal end portion on said hollow tube.
Claim 3
Dependent Claim
13 words
The device of claim 1 wherein said wire-like member is stainless steel wire.
Claim 4
Dependent Claim
23 words
The device of claim 2 wherein said deformable distal loop has a diameter greater than the inner cross-sectional diameter of said hollow tube.
Claim 5
Dependent Claim
18 words
The device of claim 3 wherein said deformable distal loop abuts the distal end of said hollow tube.
Claim 6
Dependent Claim
21 words
The device of claim 4 wherein said frangible proximal end portion is marked on said hollow tube with a score line.
Claim 7
Dependent Claim
26 words
The device of claim 5 wherein the partially tightened slip knot is engaged about the tube with five loops disposed around the circumference of the tube.
Claim 8
Dependent Claim
33 words
The device of claim 6 wherein the partially tightened slip knot terminates with a pulling end of the filamentary strand, wherein the slip knot can be fully tightened by pulling said pulling end.
Claim 9
Dependent Claim
21 words
The device of claim 7 wherein the slip knot, when fully tightened, allows sliding movement proximally and prevents sliding movement distally.
Claim 10
Dependent Claim
20 words
The device of claim 8 wherein the knot is tightened sufficiently to effectively ligate a bodily vessel or approximate tissue.
Claim 11
Dependent Claim
14 words
The device of claim 9 wherein the hollow tube has a tapered distal end.
Claim 12
Dependent Claim
15 words
The device of claim 10 wherein the hollow tube is composed of a flexible plastic.
Claim 13
Dependent Claim
16 words
The device of claim 11 wherein the filamentary strand is composed of a surgical suture material.
Claim 14
Dependent Claim
11 words
The device of claim 12 wherein the suture material is bioabsorbable.
