ABSTRACT:
A suture anchor retriever is adapted to remove a suture anchor from bone or other bodily member, the suture anchor being threaded and having a proximally-extending connector portion provided with a bore for receiving a suture, and having a pair of channels extending proximally to a proximal end of the connector portion. The anchor retriever comprises a stem portion having a socket portion at a distal end thereof, the socket portion being configured to fit snugly around the connector portion and within the channels so as to engage the suture anchor connector portion both externally and internally thereof, and a grip portion fixed to the stem portion at a proximal end of the stem portion. The stem portion is turnable around a lengthwise axis thereof by manipulation of the grip portion so as to bring surfaces of the socket portion to bear against complementary surfaces of the anchor connector portion, whereby to turn the anchor in the bone so as to retrieve the anchor from the bone.
