First Claim
1. An apparatus for delivering a closure element to an opening formed in a wall of a body lumen or body tissue, comprising:
- carrier tube having an outer surface retaining said closure element in a substantially tubular configuration, 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.

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.

12. An apparatus for delivering a closure element to an opening formed in a wall of a body lumen or body tissue, comprising:
-
carrier tube having 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 retaining a closure element in a substantially tubular configuration at the distal portion; 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for closing an opening formed in a wall of a body lumen or body tissue, comprising:
-
positioning a carrier tube adjacent to the opening, the carrier tube having a distal end with an outer surface retaining a closure element in a substantially tubular configuration, said carrier tube having a lumen and being configured to split into carrier flaps; splitting a distal end of the carrier tube with a splitter so as to form the carrier flaps that deform outwardly over the splitter; and deploying said closure element from the outwardly deformed carrier flaps of the carrier tube and over the splitter so that said closure element engages at least a portion of said wall of said body lumen or said body tissue whereby said opening is drawn substantially closed. - View Dependent Claims (21, 22)

23. A clip for closing an opening formed in a wall of a body lumen or body tissue, the clip comprising:
a shape-memory clip having a relaxed configuration with a substantially annular body defining a lumen with a plurality of tines directed inwardly from the body, the clip being in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a substantially trapezoidal longitudinal cross-sectional profile and a proximal portion having the plurality of tines being longitudinally and distally directed with a first tine of the plurality being more distally oriented compared to a substantially opposite second tine being more proximal when the clip is disposed in a clip applier, wherein the clip relaxes from the retaining configuration to the relaxed configuration when the clip is being released from the clip applier. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)

32. A clip applier apparatus for delivering a clip to an opening formed in a wall of a body lumen or body tissue, the clip applier comprising:
-
a shape-memory clip being in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a substantially trapezoidal longitudinal cross-sectional profile and a proximal end having a plurality of tines being longitudinally directed with a first tine of the plurality being more distally oriented compared to a substantially opposite second tine being more proximal when the clip is disposed in a clip applier; a carrier tube having an outer surface configured for slidably retaining the clip in the retaining configuration and slidably delivering the clip in the deploying configuration. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A method for closing an opening formed in a wall of a body lumen or body tissue, the method comprising:
-
positioning a carrier tube adjacent to the opening, the carrier tube having a distal portion with an outer surface retaining a shape-memory clip in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a substantially trapezoidal longitudinal cross-sectional profile and a proximal end having a plurality of tines being longitudinally directed with a first tine of the plurality being more distally oriented compared to a substantially opposite second tine being more proximal when the clip is disposed in a clip applier; pushing the clip over a distal end of the carrier tube so that the clip retracts to a deploying configuration having a substantially tubular shape; and ejecting the clip from the carrier tube so that at least a portion of the plurality of tines engage a portion of the wall of the body lumen or the body tissue whereby the opening is drawn substantially closed, wherein the clip relaxes from the deploying configuration to a relaxed configuration having a substantially annular body defining a lumen with a plurality of tines directed inwardly from the body. - View Dependent Claims (44, 45, 46, 47, 48, 49)
