Intended Use
The Blue Torch Medical Technologies CaverMap Surgical Aid is intended to provide stimulation to the body to locate and identify nerves and to test their excitability. The device is designed as an adjunct to the current open or laparoscopic prostatectomy and open colorectal procedures in which a nerve sparing technique is used. The Surgical Aid is not designed to replace the surgeon’s expertise in mapping out the neurovascular bundles.

CaverMap must be administered under a doctor's prescription to provide medical benefit.  CaverMap is often not eligible for a patient's insurance company reimbursement. An ABN Form is required to receive patient payments.
