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.

Claims

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.

2. The apparatus of claim 1, further comprising a trigger assembly operatively associated with the elongate member and extending from the housing.

3. The apparatus of claim 1, further comprising another shaft disposed within the shaft, the another shaft receiving the tissue locating shaft associated with the tissue locating structure.

4. The apparatus of claim 1, wherein the elongate member and the shaft slide relative to one another.

5. The apparatus of claim 1, wherein the tissue locating structure has a substantially rounded distal tip.

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.

7. The apparatus as recited in claim 6, further comprising a tissue locating shaft associated with the tissue locating structure, the tissue locating shaft extending through the first lumen of the first block.

8. The apparatus as recited in claim 6, further comprising an actuator operatively coupled to the housing and the tissue locating structure, the actuator being configured to selectively move into the housing to deploy the tissue locating structure.

9. The apparatus as recited in claim 8, the actuator including two spaced apart portions configured to receive a tissue locating shaft, operatively associated with the tissue locating structure, therebetween.

10. The apparatus as recited in claim 6, wherein the first block and the second block have cooperating engagement structures.

11. The apparatus as recited in claim 10, wherein the cooperating engagement structures include at least one detent.

12. The apparatus as recited in claim 6, wherein the second block and the third block have cooperating engagement structures.

13. The apparatus as recited in claim 6, wherein the housing comprises a plurality of grooves configured to slidably receive a portion of the second block and the third block.

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.

15. The system as recited in claim 14, further comprising an actuator operatively coupled to the housing and the tissue locating structure, the actuator being configured to selectively move into the housing to deploy the tissue locating structure.

16. The system as recited in claim 15, further comprising a biasing spring operatively coupled to the actuator.

17. The system as recited in claim 15, the actuator including an aperture configured to receive a tissue locating shaft associated with the tissue locating structure.

18. The system as recited in claim 17, the actuator including two spaced apart portions configured to receive the tissue locating shaft.
