Knotless suture anchor and driver

摘要

A suture anchor comprises a tubular body having an axial bore therethrough and having one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole, such as threads. A lateral port passes through the body from the bore to the exterior surface. A length of suture for attaching soft tissue to bone passes down along the exterior surface over the one or more purchase enhancements, over a distal end of the body, up into the bore through and then back out of the bore and up along the exterior surface over the one or more purchase enhancements.

主权项

1. A method for affixing tissue to bone comprising the steps of:
passing a length of suture through the tissue; loading the length of suture into suture anchor assembly, the suture anchor assembly comprising:
a suture anchor which comprises a tubular body with an axial bore therethrough and a lateral port through the body from the bore to an exterior surface of the body;a driver engaged to a proximal portion of the body; anda suture passer comprising an elongated flexible member passing along the driver, along an exterior of the body at its proximal portion, through the lateral port and into the axial bore with a distal end of the suture passer extending out of a distal section of the axial bore and bearing a suture engager; the step of loading comprising passing the length of suture through the suture engager; pulling the suture passer to pull the suture engaged in its suture engager through the suture anchor body axial bore and out of the lateral port; implanting the suture anchor into the bone via the driver.
