Abstract:
A temperature feedback device and method is provided for the monitoring of tissue treatment status during the application of surgical heating energy. In a preferred embodiment a function of the temperature over time is used to determine when coagulation of tissue has occurred to a desired degree. Preferably an electrosurgical hemostatic energy is used to coagulate tissue. A feedback signal is provided to a user or to a controller of an electrosurgical energy source to control delivery of energy to the tissue.
