Abstract
An apparatus, method and kit are provided for removal of polyps, especially pursuant to colonoscopic surgery. The apparatus includes an endoscopic guide tube, a heating element, a power transmitting element traversing through the guide tube and communicating with the heating element, at least one temperature sensor for measuring temperature near the polyp, and optionally an external monitor for receiving temperature data from the sensor and then activating a power source for adjusting the temperature of the heating element in a controlled manner. An operator/physician can manually set the temperature range and temperature increase rate, but preferentially this is achieved automatically through a pre-programmed computer schedule.
