Patent ID: 8734469

Claim:
A suture clip applier, comprising: a housing; an elongated plunger slidably supported in the housing, the plunger having a distal end portion disposed within the housing and a proximal end portion extending from a proximal end of the housing, wherein the plunger defines a race formed in a surface thereof, the race includes a plurality of portions each defining a cam surface of varying depth; a hollow tube extending distally from the housing and defining a lumen therethrough; an actuation member having a distal end extending into the hollow tube and a proximal end operatively engaged with the plunger; a working tip coupled to a distal end of the hollow tube, wherein the working tip has a substantially U-shaped transverse cross-sectional profile defining a channel having a base wall and a pair of spaced apart side walls, wherein the working tip defines: a lower contact surface along an internal face of the base wall, and an upper contact surface defined along an upper end surface of each side wall, wherein the upper contact surface of each side wall includes: a distal recess formed near a distal end of thereof and a proximal recess formed proximal of the distal recess; and an internal retaining surface on both side walls parallel to the base wall, wherein the distal end of the actuation member is configured to engage a suture clip loaded into the working tip; and a rocker arm having a distal end portion and proximal end portion, the rocker arm has a follower pin extending therefrom near the distal end portion thereof and a retaining pin near the proximal end portion thereof, whereby the rocker arm is pivotally attached to the housing by the retaining pin and the follower pin is slidably disposed with in the race of the plunger to modulate the motion of the plunger and actuation member.
