Abstract

Interlocking tissue anchor apparatus and methods 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. Anchor assemblies can be delivered via the tissue manipulation assembly into or through the tissue. The anchors can incorporate various temporary interlocking features or spacing elements between one another to ensure that an anchor is not prematurely ejected from the needle assembly. This allows the anchor assembly to be advanced distally as well as withdrawn proximally within a deployment sheath while avoiding inadvertently ejecting an anchor.
