Abstract
The bone anchor implantation device of the present invention comprises a shaft or body having a grip at a first end of the shaft, an anchor mount at a distal end of the shaft, and a bone anchor removably mounted in the anchor mount. The shaft is preferably bent so that the anchor mount generally faces the grip such that the bone anchor can be implanted at an anchoring site in a bone by pulling rearwardly on the device. The body is adapted to be separable from the anchor after the anchor has been implanted in bone. A suture thread is attached to the bone anchor such that the suture thread is accessible to a surgeon using the device after the bone anchor has been implanted in bone and after the body has been separated from the bone anchor. The shaft is at least partially hollow, and the suture thread is housed in the shaft. The anchor mount comprises a cannula at the distal end of the shaft. The cannula is sized to removably receive an end of the anchor.
