Suture clip applier
First Claim
1. 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, andan 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.

Abstract
Suture clip appliers, suture clips and methods of their use for securing sutures during an endoscopic or laparoscopic procedure are provided, wherein the method includes the steps of providing a suture clip applier having a working tip configured to retain and fire a suture clip; providing a suture clip having a biased closed configuration; loading the suture clip into the working tip of the clip applier; translating the suture clip distally relative to the working tip to a first position wherein the suture clip is splayed open; inserting a suture into the opened suture clip; and translating the suture clip distally relative to the working tip such that the suture clip is ejected from the working tip and biased to the closed configuration to close on and to retain the suture.

9. A suture clip applier system, comprising:
-
a suture clip applier for filing a suture clip onto a suture, the clip applier including; 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, the plunger defining a race formed in a surface thereof, the race including 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 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 in 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 in and the follower in is slidably disposed with in the race of the plunger to modulate the motion of the plunger and actuation member; and a suture clip loadable into and deployable from the working tip, the suture clip including; an elongated flexible beam having a distal end portion, a proximal end portion, a top surface and a bottom surface, the flexible beam further including a pair of arms extending laterally therefrom; and an elongated rigid channel, wherein the elongated rigid channel has a substantially U-shaped transverse cross-sectional profile with a horizontal base wall and vertical side walls having a distal end portion and proximal end portion, wherein each vertical side wall defines a holding step formed in an upper edge thereof; wherein the flexible beam and the channel are coupled to one another at their proximal end portions; wherein the pair of arms of the flexible beam are in registration with a corresponding holding step formed in the upper edge of the vertical side walls; and wherein, as the suture clip is urged in a distal direction relative to the working tip, the flexible beam is splayed apart from the channel to open the suture clip for receipt of a suture therein. - View Dependent Claims (10, 11, 12, 13, 14, 15)
