Ligation clip and clip applier
First Claim
1. A surgical ligation clip, comprising:
- a longitudinal axis;
a support member;
a clamping arm;
a connector joining said support member and said clamping arm; and
first and second enlarged ends defined on said support member and said clamping arm, respectively, said first and second enlarged ends including first and second wire loops, respectively integrally formed with said support member and said clamping arm of the clip, each of said first and second wire loops having a width transverse to the longitudinal axis of said clip, said clip having a maximum height perpendicular to the longitudinal axis of said clip and the transverse widths of said first and second wire loops that is less than the transverse width of at least one of said first and second wire loops.

Abstract
The ligation clip applicator and ligation clip design are provided which are particularly applicable to placement of a surgical ligation clip during a laparoscopic surgical procedure. The clip includes a support member and a clamping arm having enlarged portions thereon. The applicator device has a magazine including first and second longitudinally extending partially closed channels within which the enlarged portions of the support member and the clamping arm are received with the clip held in an open position. First and second articulated jaws are attached to the magazine and have first and second channel extensions therein aligned with the first and second channels of the magazine, so that a clip can be received from the magazine in the jaws with the first and second enlarged portions of the support member and the clamping arm being received in the first and second channel extensions of the jaws. The channel extensions include first and second releasing openings. The jaws are closed about a vessel to pre-clamp the vessel. The clip is pushed forward into the jaws to a position where the enlarged portions of the support member and the clamping arm are aligned with the releasing openings and the support member and the clamping arm are released allowing the support member and the clamping arm to move toward each other to ligate the vessel therebetween.

10. A wire spring clip for ligating a lumen, comprising:
a transverse spindle having a first free end and a bend which leads to a first longitudinal member which terminates in a first wire loop, said first wire loop leading to a second longitudinal member lying parallel to said first longitudinal member and spaced there from, said first wire loop having a transverse dimension greater than a transverse distance across said first and second longitudinal members, said second longitudinal member terminating in a coil spring wrapped around said transverse spindle, said coil spring leading to a third longitudinal member which terminates in a second wire loop, said second wire loop terminating in a second free end. - View Dependent Claims (11, 12, 13, 14, 15)

16. A surgical ligation clip having a longitudinal axis, a distal end, and a proximal end opposite the distal end, comprising:
-
a clamping arm along the longitudinal axis of the clip having a first wire loop away from the proximal end of the clip;
a support member long the longitudinal axis of the clip having two parallel longitudinal members with a recess therebetween, said recess being adapted to receive at least a portion of said clamping arm therethrough, said support member having a second wire loop away from the proximal end of the clip;
a connector at the proximal end of the clip, said connector joining said support member and said clamping arm, said first wire loop and said second wire loop each having a width transverse to the longitudinal axis of the clip that is greater than a combined width of said two parallel longitudinal members and the recess therebetween that is transverse to the longitudinal axis of the clip. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A surgical ligation lip having a longitudinal axis, a distal end, and a proximal end opposite said distal end, said clip comprising:
-
a clamping arm oriented generally along the longitudinal axis of said clip having a first wire loop proximate said distal end of said clip;
a support member oriented generally along the longitudinal axis of said clip having a second wire loop proximate said distal end of said clip; and
a connector at said proximal end of said clip, said connector joining said support member and said clamping arm, said clip being formed of a single piece of wire having a first free end terminating at said connector and a second free end terminating at one of said first and second wire loops. - View Dependent Claims (28, 29, 30, 31, 32, 33)
