ABSTRACT:
A fastener system for utilizing an H-shaped fastener which is composed of a pair of shaft members having a diameter of approximately 1 mm that are interconnected by a bridge shaft resiliently joined to the shaft members to form the H-shape. The shaft members have sufficient columnar resistence to bending to permit a shaft member to be compressively inserted into body tissue. A fixation tool carries the fastener for injection into body tissue and has a housing with a needle tip of approximately 5 mm in length. The needle tip has a longitudinally extending slot into which the bridge shaft of the H-shaped fastener member is captively held by interference fit. A setting rod is extendible through the needle tip and bears against a shaft of the H-shaped fastener such that an external force applied to the setting rod will be transmitted to the fastener to drive it into the body tissue.
