Tissue fixation assembly having prepositioned fasteners and method

摘要

A tissue fastener assembly delivers a fastener for deployment. The assembly includes a fastener including a first member, a second member, the first and second members having first and second ends, and a flexible connecting member fixed to each of the first and second members intermediate the first and second ends and extending between the first and second members. The first member has a longitudinal axis and a through channel along the axis. The assembly further includes a deployment wire slidingly received within the through channel of the first member that pierces into the tissue and guides the first member through the tissue, a guide structure defining a lumen that receives the fastener and deployment wire and guides the deployment wire and fastener to the tissue, and a fastener configuration structure that orientates the second member in a predetermined position relative to the first member within the lumen for dependable deployment.
