Abstract
Abstract An intracorporeal ligature tying device enables a surgeon to tie various types of knots within the body cavity of a patient during endoscopic surgery. The tying device comprises: (a) a needle holder having a longitudinal channel running though the length of the needle holder, the needle holder having a proximal end and a distal end; (b) a longitudinal groove located on an outside surface of the needle holder, the groove terminating at a location on the needle holder prior to the distal end of the needle holder, at least a final portion of the groove being covered; and (c) a wire located in the groove, the wire being made from a memory material. The wire is slidably positioned within the groove so that in a retracted position, the wire terminates in the covered portion of the groove, and in an advanced position, an end of the wire extends beyond the covered portion of the groove and forms a hook to aid in tying a ligature within a patient's body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
An intracorporeal ligature tying device, comprising: (a) a needle holder having a longitudinal channel running though the length of said needle holder, said needle holder having a proximal end and a distal end; (b) a longitudinal groove located on an outside surface of said needle holder, said groove terminating at a location on said needle holder prior to said distal end, at least a final portion of said groove being covered; and (c) a wire located in said groove, said wire being made from a memory material, said wire being slidably positioned within said groove so that in a retracted position, said wire terminates in said covered portion of said groove, and in an advanced position, an end of said wire extends beyond said covered portion of said groove and forms a hook to aid in tying a ligature within a patient's body.
Claim 2
Dependent Claim
143 words
An intracorporeal ligature tying device, comprising: (a) a needle holder having a longitudinal channel running though the length of said needle holder, said needle holder having a proximal end and a distal end; (b) a longitudinal groove located on an outside surface of said needle holder, said groove terminating at a location on said needle holder prior to said distal end, at least a final portion of said groove being covered; and (c) a wire located in said groove, said wire being made from a memory material, said wire being slidably positioned within said groove so that in a retracted position, said wire terminates in said covered portion of said groove, and in an advanced position, an end of said wire extends beyond said covered portion of said groove and forms a hook to aid in tying a ligature within a patient's body.
Claim 3
Dependent Claim
38 words
The intracorporeal ligature tying device of claim 1 wherein, a needle and a ligature are passed through said longitudinal channel of said hollow needle holder so as to extend from the distal end of said hollow needle holder.
Claim 4
Dependent Claim
26 words
The intracorporeal ligature tying device of claim 2, wherein said distal end of said needle holder is shaped complementary to a cross section of said needle.
Claim 5
Dependent Claim
32 words
The intracorporeal ligature tying device of claim 2 further comprising, a push button attached to a proximal end of said wire in order to advance and retract said wire in said groove.
Claim 6
Dependent Claim
88 words
An intracorporeal ligature tying device, comprising: (a) a hollow needle holder having a proximal end, a distal end, and a groove running longitudinally along an outside surface of said hollow needle holder; (b) a wire longitudinally positioned within said groove; and (c) a hook movably attached to said outer surface of said hollow needle holder at a location proximate to said distal end of said hollow needle holder, said hook being connected to said wire so that said wire causes said hook to move into an operational position.
Claim 7
Dependent Claim
88 words
An intracorporeal ligature tying device, comprising: (a) a hollow needle holder having a proximal end, a distal end, and a groove running longitudinally along an outside surface of said hollow needle holder; (b) a wire longitudinally positioned within said groove; and (c) a hook movably attached to said outer surface of said hollow needle holder at a location proximate to said distal end of said hollow needle holder, said hook being connected to said wire so that said wire causes said hook to move into an operational position.
Claim 8
Dependent Claim
25 words
The intracorporeal ligature tying device of claim 5 wherein, said hook is attached to said outer surface of said hollow needle device by a hinge.
Claim 9
Dependent Claim
31 words
The intracorporeal ligature tying device of claim 5 further comprising, a push button attached to a proximal end of said wire in order to move said hook into said operational position.
