Abstract
A medical device for photodynamically treating cancerous tissue, such as prostate cancer, comprising a body, a needle extendable from the body and at least one light-emitting (e.g., laser) diode mounted on the needle. The body is sized and configured for introduction into the urethra of a patient. The needle is movable between a retracted position housed substantially within the cylindrical body, and a deployed position in which the needle extends from the cylindrical body to enable it to penetrate into prostate tissue. The light-emitting diode is adapted to emit light to activate a photosensitizing agent (e.g., porfimer sodium) in or adjacent cancerous tissue in the prostate. Methods of treating cancer and other embodiments of medical devices for cancer treatment are also disclosed.
