Abstract

The present disclosure relates to an anchor. The anchor includes a suture bridge having a proximal end and distal end. The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.

Dependent claims

An anchor comprising:

a suture bridge having a proximal end and distal end, the distal end of the suture bridge having a thickness greater than a thickness of the proximal end of the suture bridge and defining the distal terminus of the anchor;
at least two ribs extending from the proximal end of the suture bridge to a proximal end of the anchor;
and
at least one open helical coil wrapping around the at least two ribs and extending, substantially, from the proximal end of the suture bridge to the proximal end of the anchor, the at least one open helical coil defining an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil;
wherein the at least one open helical coil and the proximal end of the suture bridge define a space extending to a region adjacent the distal end of the suture bridge, the space configured for receipt of a distal end of a delivery device, such that the distal end of the suture bridge projects beyond the distal end of the delivery device.
