Bioabsorbable tack for joining bodily tissue and in vivo method and apparatus for deploying same

摘要

A cannulated bioabsorbable tack has annular ribs configured to enhance fixation to tissue, such as bone, and is particularly effective for attaching soft tissue to bone, such as ligaments or muscles in the shoulder. Apparatus and method for deploying the tack facilitate arthroscopic surgical procedures for attaching or joining tissue.
