Resettable clip applier and reset tools
First Claim
1. An apparatus for delivering a closure element to an opening formed in a wall of a body lumen, the apparatus comprising:
- a closure device configured to deliver a closure element and receive an externally inserted reset member and an externally inserted spacer selectively engageable with a portion of said closure device to reset said closure device, said closure device comprising;
a locator assembly having a distal end region extendable into an opening formed in a wall of a body lumen, said distal end region selectably contacting said wall of said body lumen;
a carrier assembly coupled with said locating assembly, said carrier assembly being adapted to retain a closure element;
a resettable triggering system coupled to and extending from said carrier assembly, said trigging system being movable toward said distal end region to advance the carrier assembly toward said distal end region;
said reset member;
said spacer; and
a housing receiving at least a portion of said resettable triggering system within said housing, said housing having a longitudinal slot configured to slidably receive at least a portion of said resettable triggering system a second longitudinal slot through said housing configured to receive a portion of said spacer, and a reset member opening separate from said longitudinal slot and said second longitudinal slot and through said housing, said reset member opening configured to receive a portion of said reset member to selectively engage with a portion of said resettable triggering system to reset said triggering system.

Abstract
An apparatus for closing a wall of a body lumen to deploy a closure element. The apparatus comprises a resettable triggering system which may be slideably moved within a housing to advance a carrier assembly and/or locating assembly, and which deploys the closure element. Upon deployment of a closure element, the carrier assembly may be positioned in a distal position and locked in place within a housing. The lock may be effected by a flexible snap fit interlocking feature which is selectively releasable. Release of the locking feature may be performed by externally insertable tools which engage the flexible snap fit and release the interlocking features. The triggering system may also include a catch which is released upon deployment of a closure element. The catch can be reset to allow the triggering system to be re-engaged into a pre-deployment condition and position.
