Temperature Controlled Heating Device and Method to Heat a Selected Area of a Biological Body
First Claim
1. A device for noninvasively controlling a temperature in a selected area of cutaneous or subcutaneous tissue, comprising:
- (a) at least one temperature generating means that heats said selected area of cutaneous or subcutaneous tissue in a discontinuous temperature application pattern, wherein said at least one temperature generating means comprises at least one light source;
(b) at least one temperature detecting means to detect said generated temperature in said selected area; and
(c) at least one temperature controlling means to control said at least one temperature generating means to maintain said generated temperature within a range of a desired temperature.

Abstract
A heating device and method is provided that controls a desired temperature in a selected area of a body part to obtain a temperature effect within the selected area for therapeutic or medical purposes. It includes temperature gathering means to generate the desired temperature in the selected area. It also includes temperature detecting means to detect the generated temperature form the selected area. It further includes temperature controlling means to control the temperature generating means to obtain that the generated temperature is within a range of the desired temperature. The device and method prevents irreversibly damaging or overheating of the selected area or the tissue surrounding the selected area. It is advantageous to applications where there is a need to accurately control the temperature in a selected area in a biological body, for instance, to deploy or evaporate a temperature sensitive agent in the selected area.
