Needle assembly for tissue manipulation
First Claim
1. A needle assembly for use in forming a tissue fold, comprising:
- a housing having a shuttle member enclosed within;
an elongate pusher adapted to be in communication with the shuttle member and extending from a distal end of the housing;
a tubular sheath adapted to receive the elongate pusher therethrough and having a proximal end which is attachable to the housing; and
an actuation member disposed on the housing, wherein articulation of the actuation member translates the elongate pusher longitudinally relative to the housing.

Abstract
Needle assemblies for tissue manipulation 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. A needle deployment assembly is deployable through the tissue manipulation assembly via a handle assembly, through the tubular member, and into or through tissue. An elongate pusher is translationally disposed within a sheath of the needle deployment assembly and can be urged distally for deploying an anchor assembly from the sheath distal end. The anchor assembly is positioned distally of the pusher within the sheath.

21. A method of deploying one or more anchors in securing a tissue fold, comprising:
-
advancing a needle body disposed on a distal end of a tubular sheath into or through a fold of tissue;
manipulating an actuation member disposed on a housing connected to a proximal end of the tubular sheath such that a shuttle member enclosed within the housing urges an elongate pusher through the tubular sheath; and
deploying at least one anchor from the tubular sheath via the elongate pusher. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
