A tissue attachment device (10) comprises a body (12) disposed along an axis (22) between a plurality of ends (14, 16), with each of the ends being configured to be inserted into tissue along the axis and to anchor itself within the tissue. One end of the device can be inserted into, e.g., bone, so that the opposite end of the device protrudes from the bone. Softer tissue (e.g., a ligament, a tendon, or cartilage) is pressed onto the exposed end of the device which becomes anchored within the soft tissue, thereby securing the softer tissue in place against the bone. Because the exposed end of the device is anchored within the softer tissue, the articular surface of the softer tissue (i.e., the surface opposite to the surface which is pressed against the bone over the exposed end of the device) is undisturbed. Accordingly, patient pain and healing time are significantly reduced. |
