Abstract
Method and apparatus for fracturing hard deposits such as urinary and biliary calculi and arteriosclerotic plaque in the human body. An elongate guide member having an apertured hollow adjacent its distal end is inserted within the body with the distal end positioned adjacent the target. A working fluid is supplied to the hollow, and an electric spark is discharged within the hollow from an external energy source for generating pulse waves in the working fluid. The resulting pulse waves express working fluid from the hollow to impinge on the target. Makeup fluid is supplied and the spark repeated. The method and apparatus also may be advantageously employed for dilating narrowing in hollow internal structure in the body.
