Abstract
Methods for effecting various surgical procedures via the use of a flexible, small diameter, catheter. The catheter includes a working head arranged to be moved, e.g., rotated, at a high rate of speed by an associated drive system. In one method the cathether with the moving head is brought into engagement with a restriction caused by an atherosclerotic deposit in an artery to effect the opening of the restriction by the dilation of the artery. In another method the catheter is used to dilate a duct or tube, e.g., a fallopian tube, eustachian tube, bile duct, etc. in a living being. In another application the catheter is used to effect the in situ valvulectomy of a section of vein within a living being. In still another method the catheter is used to disintegrate a stone, such as a kidney or gall stone, in the body of a living being. In yet another method, the catheter is used to stop spasm in a lumen in a living being. A catheter is also disclosed which is particularly configured to effect an in situ valvulectomy or stone disintegration procedure.
