ProSense™ is a minimally-invasive solution that destroys tumors safely, quickly, and painlessly, without the need for surgery. The ProSense™ system uses a freezing technique – cryoablation – to destroy the tumor. We use liquid nitrogen instead of argon gas to reach freezing temperatures, as it allows for faster and more stable freezing. It also may enable the physician to offer you the procedure in the comfort of a clinic instead of at a hospital or medical center. The physician will insert a very thin probe into the tumor and then will use liquid nitrogen to destroy it. Within less than 30 minutes, the tumor is destroyed without damaging surrounding tissue and the procedure is completed. You should feel no pain at all during the procedure and should be able to resume regular activities very quickly and significantly faster than after surgery.
