Abstract
Apparatus and method are described for selective cutting of the transverse carpal ligament of a patient. The instrument includes spaced-apart teeth which are supported on a first arm and a press member which is carried by a second arm. The teeth are prevented from contacting tissue when the first arm is inserted into, or retracted from, the carpal tunnel. After insertion of the first arm into the carpal tunnel, the teeth are exposed to the transverse carpal ligament and the first and second arms are moved towards each other to force the teeth into the transverse carpal ligament to perforate the ligament and enable it to elongate.
