A trocar is a sharp-pointed instrument used with a cannula for piercing a vessel or chamber to facilitate insertion of the cannula sold under the Symmetry Surgical, CareFusion, and Ambler Surgical brand names.

Reason: The reason these devices are being withdrawn from the market by Instrumed is that Instrumed did not market these devices prior to September 26, 1976, and therefore, does not meet all FDA requirements to market the devices as "Pre-Amendment" devices.
