The drive wire extends through the lumen of the elongate shaft and is operatively connected to the handle. The device includes a drill mechanism assembly with a drill bit disposed near the distal end of the elongate shaft. ## Claims ### Claim 1 A lithotriptor device comprising: a proximal handle; an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft; a wire basket distally attached to a drive wire, the drive wire extending through the lumen of the elongate shaft and operatively connected to the handle; and a drill mechanism assembly comprising a drill bit and disposed near the distal end of the elongate shaft. ### Claim 2 (depends on 1) The lithotriptor device of claim 1, wherein the drill mechanism assembly comprises a fluid-driven turbine. ### Claim 3 (depends on 1) The lithotriptor device of claim 1, wherein the drill mechanism assembly comprises an electronically-driven rotor. ### Claim 4 (depends on 1) The lithotriptor device of claim 1, wherein the drill mechanism assembly comprises a mounting plate securing the drill mechanism assembly to the elongate shaft. ### Claim 5 (depends on 1) The lithotriptor device of claim 1, further comprising a wire guide lumen structure. ### Claim 6 (depends on 5) The lithotriptor device of claim 5, wherein the wire guide lumen structure is mounted outside the lumen of the elongate shaft. ### Claim 7 (depends on 1) The lithotriptor device of claim 1, wherein the handle comprises a switch that is controllingly connected with the drill mechanism. ### Claim 8 (depends on 7) The lithotriptor device of claim 7, wherein the control connection between the switch and the drill mechanism comprises a selected one of a fluid flow passage or an electronic communication connection. ### Claim 9 (depends on 7) The lithotriptor device of claim 7, wherein the switch is selected from a dual-state (on/off) switch and a rheostat switch. ### Claim 10 (depends on 1) The lithotriptor device of claim 1, wherein the elongate shaft comprises a generally cylindrical metal coil. ### Claim 11 (depends on 1) The lithotriptor device of claim 1, wherein the basket and the drill mechanism are configured and disposed such that an object drawn proximally in the basket will contact the drill bit of the drill mechanism ### Claim 12 A method for crushing an object, said method comprising the steps of: providing a medical lithotriptor device comprising: a proximal handle; an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft; a basket distally attached to a drive wire, the drive wire extending through the lumen of the elongate shaft and operatively connected to the handle; and a drill mechanism assembly comprising a drill bit and disposed near the distal end of the elongate shaft. engaging the basket around an object; and actuating the handle such that the drive wire is drawn proximally into the elongate shaft and the basket is drawn tightly around the object. ### Claim 13 (depends on 12) The method of claim 12, further comprising a step of actuating the drill mechanism such that the drill bit contacts the object. ### Claim 14 (depends on 13) The method of claim 13, further comprising a step of actuating the handle such that a tension of the basket around the object is reduced. ### Claim 15 (depends on 12) The method of claim 12, wherein the drill mechanism is powered by a selected one of a fluid-driven turbine or an electric motor. ### Claim 16 (depends on 12) The method of claim 12, further comprising a step of breaking the object into two or more fragments. ### Claim 17 (depends on 16) The method of claim 16, further comprising a step of using the basket to move at least one of the two or more fragments from a first location to a second location. ### Claim 18 (depends on 12) The method of claim 12, wherein the lithotriptor device further comprises a wire guide lumen structure. ### Claim 19 (depends on 18) The method of claim 18, wherein the wire guide lumen structure is mounted outside the lumen of the elongate shaft. ### Claim 20 A lithotriptor device comprising: a proximal handle; an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft; a wire basket distally attached to a drive wire, the drive wire extending through the lumen of the elongate shaft and operatively connected to the handle; and a fluid turbine-driven drill means comprising a drill bit, said drill means being disposed such that the drill bit projects distally from the elongate shaft.
