Cranial fixation system

Evaluation of a Bioabsorbable Polyester Blend for Use in Medical Devices CRANIOSORB a Novel Cranial Fixation System... 

The rivet and pin system is also a novel design as it provides a rapid fixation technique with no need for tapping of the drill holes. The fixation strength of the rivets was 35 pounds. This is comparable to absorbable screw fixation of similar dimensions. A user-friendly rivet applier has also been developed (14), A secondary advantage of the rivet design is the lack of a sharp tip that is often found on metal screws. Thus, the placement of the rivet beyond the inner cranial surface poses less risk of a dural tear.
