Abstract

An apparatus for placement into an opening formed in a wall of a body lumen to deploy a closure element. The apparatus comprising a housing having a handle portion formed at a distal end, the handle portion configured to be engaged by a user when advancing the housing to deploy the closure element. A triggering element deploys the closure device and can at least be partially formed in the housing. A throw reducing mechanism can slide relative to the housing and reduce the distance a user must stretch a hand to move a triggering system within the housing. The housing can include, or be connected to, a handle member having one or more expansion members which expand to provide a stable base for manipulating the apparatus.

Claims

1. An apparatus for delivering a closure element to an opening formed in a wall of a body lumen, the apparatus comprising:

a locator assembly having a distal end region extendable into an opening formed in a wall of a body lumen;

a carrier assembly coupled with said locator assembly, said carrier assembly being adapted to retain a closure element;

a triggering system coupled to and extending from said carrier assembly, said trigging system being configured to advance said carrier assembly toward said distal end region, and said triggering system comprising a trigger element adapted to deploy said closure element; and

a housing receiving said locator assembly, said carrier assembly, and said triggering system, wherein said trigger element of said triggering system is at least partially integrally formed in said housing.

2. The apparatus of claim 1, wherein said triggering system comprises an energy storing member adapted to cause relative motion between said carrier assembly and said triggering system.

3. The apparatus of claim 2, wherein said trigger element is configured to release energy from said energy storing member.

4. The apparatus of claim 3, wherein said energy storing member is adapted to cause relative motion between said carrier assembly and said triggering system upon release of energy from said energy storing member caused by said trigger element.

5. The apparatus of claim 3, wherein said trigger element comprises a trigger button.

6. The apparatus of claim 5, wherein said trigger button comprises a flexible tab integral with said housing.

7. The apparatus of claim 6, wherein said flexible tab is adapted to release energy from said energy storing member upon being depressed.

8. The apparatus of claim 3, wherein said housing comprises an exterior surface and wherein said trigger element is integrally connected to said exterior surface.

9. The apparatus of claim 8, wherein said trigger element is about flush with said exterior surface.

10. The apparatus of claim 9, wherein said trigger element is elevated with respect to said exterior surface.

11. The apparatus of claim 10, wherein said trigger element comprises:

an elevated envelope integral with said housing; and

a trigger button, said trigger button having an interior portion housed within said envelope and further comprising an exterior portion external to said envelope, wherein said exterior portion is adapted to cause said energy storing member to release energy when said exterior portion is depressed.
