### INTENDED USE

Aesculap's CranioFix and CranioFix2 System are intended for use in the fixation of cranioplasty plates, covering burr holes, and fixation of cranial fractures.

### DEVICE DESCRIPTION

The CranioFix and CranioFix2 Clamp System consist of sterile, titanium implants (Clamps) and associated manual instruments. The Clamps are available in three sizes: 11mm, 16mm, and 20mm. The clamp consists of two concave disks which are connected with a pin through the center. The pin is securely attached to the lower disk; the upper disk is loosely mounted onto the pin. Each disk has rows of teeth extending along the edge of the concave side. The disks are mounted onto the pin with the teeth of each one facing the teeth of the other. The disks of the CranioFix Titanium Clamp (11mm) are solid (no drainage holes). The disks of the CranioFix Titanium Clamp (16mm and 20mm) have open areas for drainage. The CranioFix2 Titanium Clamp (11mm, 16mm, and 20mm) have a sleeve securely attached on the end of the pin. During the fixation, the lower disk comes to rest against the inner surface of the cranium and the upper disk comes to rest against the outer surface of the cranium.
