Clip applier and methods of use
First Claim
1. An apparatus comprising:
- a housing;
a shaft slidably extending from the housing;
a tissue locating structure selectably deployable distal a distal end of the shaft;
an actuator operatively coupled to the housing and the tissue locating structure and being configured to selectively move distally into the housing to radially expand the tissue locating structure and move proximally to radially retract the tissue locating structure, the actuator including two spaced apart portions configured to receive a tissue locating shaft, operatively coupled to the tissue locating structure, therebetween;
a closure structure disposed within the shaft and selectably deployable from the shaft;
an elongate member operatively associated with the closure structure, the elongate member and the shaft cooperating to deploy the closure structure.

Abstract
An apparatus for delivering a closure element can include a splittable carrier tube and a splitter to split the tube. The carrier tube can have an outer surface retaining a closure element in a tubular configuration and can be split into radially-expandable flaps. A closure element can have a shape-memory body having a relaxed configuration with a planar-annular body defining a lumen with tines directed inwardly from the body. The clip can be held in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile and a proximal end having the tines being longitudinally directed with a first tine being more distally oriented compared to a substantially opposite second tine being more proximal, and retracting to a deploying configuration having a tubular shape with a rectangular longitudinal cross-sectional profile with the first tine being even with the second tine when being delivered.

6. An apparatus for deploying a closure structure, the apparatus comprising:
-
a housing having a distal end with a proximally facing distal wall portion; a tissue locating structure selectably deployable distal to the distal end of the housing; a first block disposed within the housing and selectively contacting the proximally facing distal wall portion of the housing, the first block having a first lumen and cooperating with a shaft extending distally from the first block and the housing; a second block movable within the housing, the second block having a second lumen aligned with the first lumen, the second block cooperating with an elongate member extending distally through at least a portion of the shaft to distally advance a closure structure within the shaft, the elongate member and the shaft cooperating to deploy the closure structure; and a third block movable within the housing, the second block and the third block being movable relative to the first block upon deployment of the closure structure. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A system comprising:
-
an introducer sheath including a hub assembly and an introducer sheath portion; and a closure delivery device selectively connected to the introducer sheath, the closure delivery device comprising a housing having a distal end with a proximally facing distal wall portion, the closure delivery device including one or more connectors configured to selectively mate with the introducer sheath to selectively secure the housing and the introducer sheath together, the closure delivery device including; a tissue locating structure selectably deployable distal to the distal end of the housing; a first block disposed within the housing and selectively contacting the proximally facing distal wall portion of the housing, the first block having a first lumen and cooperating with a shaft extending from the first block and the housing; a second block movable within the housing, the second block having a second lumen aligned with the first lumen, the second block cooperating with an elongate member extending through the shaft, the elongate member and the shaft cooperating to deploy a closure structure; and a third block movable within the housing, the second block and the third block being movable relative to the first block upon deployment of the closure structure. - View Dependent Claims (15, 16, 17, 18)
