Abstract:
1. A medical device for applying energy to tissue, the medical device comprising: an elongate member having a proximal portion and a distal portion; a transducer assembly located entirely within an interior of the elongate member and towards said distal portion of said elongate member, an RF tissue-cutting electrode comprising an electrically conductive tip located entirely distally to said transducer assembly at a distal end of said distal portion of said elongate member, said tip having a front face covering said distal end of said distal portion, said tip being adapted to conduct energy to tissue, said tip having a front and back surface, said back surface being in acoustical communication with said transducer assembly wherein said tip is adapted to communicate a source signal from said transducer assembly out through said surface, said tip also being adapted to communicate a reflected signal said front surface to said transducer assembly; and at least two conducting members extending through at least a portion of said elongate member, at least one of said conducting members capable of electrically coupling an RF energy supply to said tip to electrosurgically remove tissue.
