Patent ID: 7022088

Claim:
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 comprising a covering having a proximal and distal end, at least one transducer having at least a first and second pole, a first conductive medium in contact with said first pole of said transducer and extending to at least a portion of an outer surface of said covering, wherein said transducer assembly is located towards a distal end of said elongate member distal portion; at least two conducting members extending through at least a portion of said elongate member, at least a first of said conducting members being electrically coupled to said first conductive medium, and a second of said conducting members extending through said proximal end of said covering and electrically coupled to said second pole of said transducer; a hollow conductive member located at the distal end of said elongate member, said hollow conductive member electrically coupled to an energy source, and a tip 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.
