Patent ID: 8864760

Claim:
A medical device for creating a region of heated tissue using temperature to monitor a desired profile of the region, the medical device, comprising: a shaft coupled to a handle, where the handle includes a connector for electrically coupling to a source of energy; a first temperature detecting element spaced axially and proximally along the shaft from a proximal end of an energy transfer portion located at a working end of the shaft; a second temperature detecting element spaced proximally from the first temperature detecting element; where the first and second temperature detecting elements are configured to independently and respectively provide a first and a second actual temperature measurement; and an energy controller capable of delivering energy from the source of energy to the energy transfer portion, the energy controller configured to control the delivering of the energy in response to comparing at least the first or second actual temperature measurements to at least one associated temperature, where the associated temperature correlates to a previously measured region of heated tissue having a known profile.
