Abstract
A bioabsorbable rivet and pin fastening device that may be used for attachment of a fixation plate to bone is described herein. The rivet having a head that is mechanically connected to two or more legs that extend generally distally from the head. The pin being radially compressible and less compliant than the legs of the rivet. The pin when inserted into the rivet will contact the internal surface of said legs to apply force on said legs in a direction perpendicular to the central axis to frictionally engage with the adjacent bone.
Claims13
A bioabsorbable biocompatible rivet and pin fastening device comprising:
- (a) a biocompatible rivet having a head with a proximal end and a distal end and a central axis, the head having an internal passage extending from the proximal to the distal end of the head that is substantially parallel to the central axis of the head, the distal end of the head being mechanically connected to two or more legs that extend generally distally from the head and have an internal surface that faces the central axis, and
- (b) a biocompatible pin having a radially compressible cross-section that is less compliant than the legs of the rivet which is adapted to be inserted into the internal passage of the rivet and which as advanced from the proximal end toward the distal end of the head of the rivet will contact the internal surface of said legs to apply force on said legs in a direction perpendicular to the central axis.

- wherein the rivet is molded with the legs in substantially the position that the legs would be in with the pin in place.
