Abstract
A medical device 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, typically an optic fiber, that carries radiant energy, typically high intensity light such as laser, into a body cavity, typically the uterus, from an energy source, typically a laser source, that is located exterior to the body. At the operative head of the device within the body cavity a portion of the transmitted radiant energy is absorbed and converted to heat. This heat is radiated or conducted from the device head substantially omnidirectionally in order to aid in destruction of tissue. Meanwhile, another portion of the transmitted radiant energy is emitted through an aperture in the device head as light energy suitable for more localized and intense heating and destruction of tissue or other organic matter. This light emission is preferably directionally transverse to an elongate body of the device head. The device is suitable for selective destruction of tissue or other matter by highly localized heating.
