ABSTRACT:
A meniscus repair anchor. The anchor includes an anchor body and a retaining head intercoupled by a flexible member. The anchor is lodged within a hollow needle. The needle is advanced into the meniscus and across the tear in an inner-to-outer direction, thereby preventing contact between the anchor body and meniscal tissue during deployment. Once the needle tip has penetrated the outer edge of the meniscus and protrudes therefrom, a stylus is used to deploy the flexibly tethered retaining head against the outer edge. The hollow needle is then retracted, causing the barbs along the anchor body to deploy internally within the meniscus. Excess length of the anchor body is cut off at the inner edge entry point of the meniscus.
