Abstract:
A device for insertion into a body lumen includes an operator unit which may be hand held by an operator. A cannula is operatively associated with the operator unit and the cannula includes two parallel lumens. At least one of two lumens terminates at its distal end before the distal end of the other lumen and wherein one of the two lumens is contained at most partially within the other lumen.

Claim (Index 6):
A method of fragmenting stones contained in a body lumen comprising:\n providing a device for insertion into a body lumen through an endoscope, the device comprising: a handpiece adapted to be held by an operator; a cannula operatively associated with the handpiece; the cannula including at least two lumens, an optical fiber lumen and an aspiration/irrigation lumen, the lumens being mounted as a unit parallel to one another along a longitudinal axis, the lumens being of a generally circular cross-section and of unequal cross-sectional size such that the circumferential wall sizes are unequal; wherein the optical fiber lumen is of a smaller cross-sectional and circumferential size and receives an optical fiber lumen is of a smaller cross-sectional and circumferential size and receives an optical fiber with a distal fiber tip which extends through and beyond the distal tip of the optical fiber lumen and the aspiration/irrigation lumen is of a larger cross-sectional and circumferential size and provides for one or more of: (a) irrigation of the body lumen and (b) aspiration of materials from within the body lumen; wherein the optical fiber receives and transmits a laser light through the optical fiber and out the distal end of the optical fiber, the laser light beam being utilized to fragment stones present in the body lumen during a stone fragmentation procedure; and wherein the optical fiber lumen is formed partially within a circumferential wall of the aspiration/irrigation lumen, wherein the distal end of the circular cross-section of the optical fiber lumen terminates before the distal end of the aspiration/irrigation lumen, wherein the optical fiber lumen continues as a half-circular shaped lumen within the circumferential all of the aspiration/irrigation lumen from the distal end of the circular cross-section of the optical fiber lumen to the distal end of the aspiration/irrigation lumen; the method further comprising: (a) an operator observing, through the endoscope, the fiber and fiber tip condition during the stone fragmentation procedure; and (b) the operator advancing the optical fiber as the optical fiber tip fragments during the stone fragmentation procedure.
