<p>A medical device (10) applies localized heat to a site in a patient's body by irradiation with light and by conduction. The device includes a radiant energy transmitting conduit (22) typically an optic fiber, that carries radiant energy, typically high intensity light such as laser, into a body cavity, typically the uterus (100), from an energy source (50) typically a laser source that is located exterior to the body through the conduit (22) and out a bulbous element (18). At the operative head of the device a portion of the transmitted radiant energy is absorbed and converted to heat and another portion of the transmitted radiant energy is emitted through an aperture in the device head as light energy suitable for more localized an intense heating and destruction of tissue.</p> |
