Clip applier and methods of use
First Claim
1. A closure element delivery apparatus comprising:
- a carrier tube having an outer surface, the carrier tube having a lumen and at least one slit at a distal end of the carrier tube, and the carrier tube being configured to split at the slits so as to form outwardly bendable carrier flaps; and
a splitter disposed adjacent to the slits so that the splitter splits the carrier tube at the distal end to form and outwardly bend the carrier flaps, the splitter being comprised of a series of combinable splitters, wherein proximally disposed combinable splitters each have a recess for receiving a proximal portion of a distally-adjacent combinable splitter.

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 has can have 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.

11. A closure element delivery apparatus comprising:
-
a carrier tube having a lumen, a total length and slits extending at least partially along said total length from a distal end, the slits being configured to split and separate a distal portion of the carrier tube into outwardly bendable carrier flaps, said carrier tube having an outer surface; and a splitter disposed adjacent to the slits so that the splitter splits the carrier tube at the distal end to form and outwardly bend the carrier flaps, wherein the splitter is comprised of at least a proximal combinable splitter and a distal combinable splitter, wherein the proximal combinable splitter has a recess for receiving a proximal end of the distal combinable splitter. - View Dependent Claims (12, 13, 14, 15, 16, 17)
