Multiple-firing suture fixation device and methods for using and manufacturing same
First Claim
1. A multiple-firing clip device, comprising:
- a plurality of suture fixation clips each having an internal hollow shaped to receive therein at least one suture;
a shaft defining a hollow interior and comprising an exterior surface and a distal fixation location in the interior;
the plurality of the clips stacked in the interior, defining a first clip, and being configured to move along a longitudinal axis;
the shaft defining a lateral opening proximal to the distal fixation location and communicating between the interior and an environment outside the exterior surface;
an elongated device movement carriage at least partly disposed within the interior of the shaft;
the device movement carriage being configured to deliver the first clip to the distal fixation location by moving the first clip longitudinally from a first proximal position into the distal fixation location and returning to a second proximal position without the first clip; and
a shuttle defining a lumen surrounding the shaft and longitudinally movable on the shaft to a distal-most position;
the shuttle comprising a body and a snare movably disposed within the body to deploy distally out therefrom;
the shuttle configured to pull a portion of the at least one suture to be captured by the snare from distal of the first clip proximally through the first clip, through a portion of the shaft, and out a side of the shaft through the lateral opening;
the shuttle comprising an interlock configured to prevent the body from moving with respect to the shaft during deployment of the snare and to prevent the snare from deploying until the shuttle is in the distal-most position.

Abstract
A multiple-firing crimp device comprises crimps, a shaft, a crimp movement assembly, and a snare. Each crimp has an internal hollow. The shaft has a distal crimping location, an exterior surface, and an interior with the clips stacked therein, the crimps moving therein along a longitudinal axis. The shaft defines a lateral opening proximal to the crimping location and communicates the interior to the environment outside the exterior surface. The crimp movement assembly within the shaft delivers the first crimp to the distal crimping location by moving the first crimp longitudinally from a first proximal position into the distal crimping location and returning to a second proximal position without the first crimp. The snare pulls at least one cord from distal of the first crimp through the first crimp and through a portion of the shaft and out the side of the shaft through the lateral opening.

15. A multiple-firing clip device, comprising:
-
a plurality of suture fixation clips each having an internal hollow shaped to receive therein at least one suture; a shaft defining a hollow interior and comprising an exterior surface and a distal fixation location in the interior;
the plurality of the clips stacked in the interior, defining a first clip having a proximal side, and being configured to move along a longitudinal axis;
the shaft defining a lateral opening proximal to the distal fixation location and communicating between the interior and an environment outside the exterior surface;an elongated device movement carriage at least partly disposed within the interior of the shaft;
the device movement carriage being configured to deliver the first clip to the distal fixation location by moving the first clip longitudinally from a first proximal position into the distal fixation location and returning to a second proximal position without the first clip;a shuttle longitudinally movable on the shaft to a distal-most position and comprising a body, a snare-extension tube disposed at least partly within the body, and a snare movably disposed within the body to deploy distally out from the body;
the shuttle configured to pull a portion of the at least one suture to be captured by the snare from distal of the first clip proximally through the first clip, through a portion of the shaft, and out a side of the shaft through the lateral opening;
the shuttle comprising an interlock configured to prevent the body from moving with respect to the shaft during deployment of the snare and to prevent the snare from deploying until the shuttle is in the distal-most position; andwherein the snare comprises a snare portion disposed within the snare-extension tube;
the snare-extension tube comprises an end portion and is external to the shaft;
responsive to the snare-extension tube moving distally with the shuttle, at least the end portion of the snare-extension tube passes through the lateral opening and up to the proximal side of the first clip; and
the body further comprises a snare extender configured to move at least a portion of the snare distally through the snare-extension tube, through the first clip, and past the distal fixation location of the shaft to secure the portion of the at least one suture temporarily and to pull at least the portion of the at least one suture through the first clip and towards the lateral opening. - View Dependent Claims (16, 17, 18, 19, 20)
