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. A vessel closure device delivery system, comprising:

a delivery device that couples to a vessel closure clip for delivering the clip onto a blood vessel;

a retractable vessel locator removeably attached to the delivery device, the distal end of the vessel locator adapted to transition from a collapsed state suitable for insertion into a vessel and an expanded state that lodges against a wall of the vessel from inside the vessel; and

a vessel closure clip.

2. A system as in claim 1, wherein the delivery device comprises a clip carrier assembly, the clip carrier assembly comprising an elongated member retaining vessel closure clip in a deliverable configuration, a pusher member adapted to deploy the vessel closure clip, and an actuator to actuate the pusher member with respect to the elongated member to deploy the clip.

3. A system as in claim 2, wherein the carrier assembly further comprises a cover member for retaining vessel closure clip on the elongated member during delivery, the cover member coupled to an actuator to release the clip during deployment

4. A system as in claim 1, wherein the vessel locator is part of a locating device sized and constructed to function as a guidewire in the collapsed state, and wherein the locating device may be used to guide the delivery device to the vessel wall.

5. A system as in claim 4, wherein the delivery device may be removed from the locating device so that the locating device can be used to delivery the procedural sheath.
