Methods of use of a clip applier
First Claim
1. 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, the carrier tube having a lumen and being configured to split into a plurality of carrier flaps;
splitting a distal end of the carrier tube with a splitter that increases in cross section from a proximal end toward a distal end of the splitter; and
deploying the closure element from the carrier flaps of the carrier tube and over the splitter, the closure element engaging at least a portion of the wall of the body lumen or the body tissue to substantially close said opening.

Abstract
A method for closing an opening formed in a wall of a body lumen or body tissue can include positioning a splittable carrier tube adjacent to the opening, the carrier tube having a splittable distal end with an outer surface retaining a closure element in a substantially tubular configuration or having an asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile. The method including splitting a distal end of the carrier tube with a splitter and deploying the closure element from the carrier flaps of the carrier tube and over the splitter to allow the closure element to engage at least a portion of the wall of the body lumen or the body tissue and substantially close the opening.

8. 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;
splitting a distal end of the carrier tube with a splitter that increases in cross section from a proximal end toward a distal end of the splitterpushing 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 a 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 the plurality of tines directed inwardly from the body. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
