Abstract

A medical device is provided which comprises a suction conduit and an energy-transmitting conduit wherein at least some of the transmitted energy is directed to the distal region of the suction conduit. The device may include an optical apparatus for directing the energy. The device has applications in lithotripsy and tissue-removal in a patient.

Claims

1. A medical device, comprising:

a first conduit having a proximal end connected to a pump which provides suction at a distal region of the first conduit; and

a second conduit having a proximal end connected to a high energy source and which transmits a high energy to a distal end;

wherein the distal end of the second conduit directs at least a portion of the high energy emitted to at least a portion of the distal region of the first conduit.
