The Contiplex C Continuous Peripheral Nerve Block Set, consisting of the peripheral nerve block needle, catheter, and related peripheral nerve block procedural accessories, is intended to provide continuous and/or intermittent inflision of local anesthetics and analgesics for peripheral plexus anesthesia and pain management during pre-operative, perioperative and post-operative periods associated with general and orthopedic surgery. The catheter may remain indwelling for up to 72 hours.
