Abstract
An expandable fastener device for attaching tissue to bone and a surgical operating technique for using it. The fastener device includes a shaft which will pierce tissue and when rotated, will drill a hole in bone with a drill point to receive the fastener in bone. The device can be drilled in place and fixed in place by actuation of the device itself. The anchor porion of the fastener device remaining in the body when the shaft is sheared and removed, is made from a a bioabsorbable polymer material and an implantable grade titanium material or alloy thereof. The portion of the fastener that captures the body soft tissue (tendon or ligaments) is biodegradable and the portion anchored to the bone is the titanium material. Another embodiment constructs the component that captures the body soft tissue into a pedal-like integral disk where each pedal flexes to conform to the shape of the bone surface adjacent thereto.
