Endoscopic suture cinch system
First Claim
1. A cinch applicator for applying a suture cinch to suture, comprising:
- a) an elongate flexible first tubular member having proximal and distal ends;
b) a relatively rigid second tubular member having proximal and distal ends, said proximal end of said second tubular member fixed to said distal end of said flexible first tubular member, said second tubular member defining a side window and defining a latch;
c) a plunger situated within said second tubular member, said plunger having an upper housing for receiving at least a portion of the cinch, a guillotine provided with a cutting edge located distally relative to said side window of said second tubular member and retractable past said side window of said second tubular member when said plunger is moved proximally relative to said second tubular member, a floor proximal to said guillotine, and a catch engaged by said latch to retain a longitudinal position of said plunger within said second tubular member;
d) a flexible shaft having proximal and distal ends; and
e) a proximal handle coupled to said proximal ends of said first tubular member and said flexible shaft to move said distal end of said flexible shaft relative to said distal end of said second tubular member.

Abstract
A two-part suture cinch includes a collar and a plug. A cinch applicator is also provided, and includes an elongate tubular member, a plunger engaged within the distal end of the tubular member, a flexible shaft extending through the tubular member and plunger, and a proximal handle for moving the shaft longitudinally relative to the tubular member. The plunger includes a distal housing for the collar of the cinch, and the plug is coupled to the distal end of the flexible shaft. The suture is thread through the collar and a portion of the applicator. Operation of the applicator draws the plug into the collar and clamps the suture between the plug and collar. In addition, once the plug is coupled in to the collar, the plunger is displaced proximally to release the two-part cinch form the applicator. A method for applying the cinch is also provided.

22. A cinch applicator for applying a suture cinch to suture, comprising:
-
a) an elongate tubular member having proximal and distal ends, said distal end including a side window and a first engagement member; b) a plunger situated within said tubular member, said plunger having a distal housing, a proximal floor, and a second engagement member engaged by said first engagement member to retain a longitudinal position of said plunger within said tubular member; c) a shaft having proximal and distal ends; and d) a proximal handle for moving said flexible shaft longitudinally relative to said tubular member from, a first position in which said distal end of said flexible shaft is located distal of said floor of said plunger, a second position in which said distal end of said flexible shaft is moved into contact against said floor of said plunger, and a third position in which said first and second engagement members are disengaged and said plunger is moved proximally relative to said tubular member. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
