Multi-position tissue manipulation assembly
First Claim
1. A handle for use in forming a tissue fold, comprising:
- an enclosure having a proximal end and a distal end; and
a needle deployment mechanism having a first position adapted to lock a needle assembly within the enclosure and allow longitudinal translation of the needle deployment mechanism to pivot a distal portion of a needle tubular member, and a second position adapted to allow longitudinal translation of the needle assembly through the needle tubular member.

Abstract
Multi-position tissue manipulation assemblies are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. One or all the articulation controls and functions can be integrated into a singular handle enclosure connectable to the tissue manipulation assembly via a rigid or flexible tubular body. A needle deployment mechanism may be positioned within the enclosure. Such a mechanism can have multiple positions adapted to lock and/or advance a needle assembly within the enclosure in a controlled manner as well as for deploying the anchor assembly.

19. A needle deployment system adapted to be retained in an enclosure, comprising:
-
an outer sleeve disposed about an inner sleeve such that the outer sleeve and the inner sleeve are configured to interlock in a corresponding manner;
wherein the outer sleeve is adapted to partially rotate relative to the inner sleeve such that the deployment mechanism defines;
a first position adapted to lock a needle assembly within the needle deployment mechanism and allow longitudinal translation of the needle deployment mechanism to pivot a distal portion of a needle tubular member, and a second position adapted to allow longitudinal translation of the needle assembly through the needle tubular member. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of deploying a needle assembly, comprising:
-
loading a needle assembly within an enclosure;
articulating a needle deployment mechanism within the enclosure to a first position such that the needle assembly is locked within the needle deployment mechanism;
translationally advancing the needle deployment mechanism relative to the enclosure such that a distal portion of a needle tubular member is pivoted;
articulating the needle deployment mechanism to a second position such that the needle assembly is longitudinally translatable through the needle tubular member. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
