Abstract:
1. A medical device for applying energy to tissue, the medical device comprising: a flexible elongate member having a proximal portion and a distal portion; a transducer assembly comprising a transducer having first and second poles; wherein said transducer assembly is located towards a distal end of said elongate member distal portion; two conducting members extending through at least a portion of said elongate member and in electrical contact with the first and second poles respectively; a hollow member located at the distal end of said elongate member, the hollow member adapted to mechanically cut tissue and wherein said hollow member is coupled to an RF energy source via one of the conducting members, a tip having a rounded surface configured to avoid damage to tissue and located at a distal end of said elongate member distal portion and having a front and back surface, said back surface being in acoustical communication with said transducer such that said tip is adapted to communicate a source signal from said transducer out through said front surface, said tip also being adapted to communicate a reflected signal from said front surface to said transducer assembly; and wherein the transducer assembly is configured to be distally moveable to a distal end of the hollow member.
