Abstract
A procedure and device for use in removing atherosclerotic plaques by inserting a multiple-lumen catheter having a cutting tip into an artery, such as the coronary artery. The cutting tip is rotated by the application of fluid pressure through an inner lumen while, if necessary, negative pressure can be applied through a separate lumen to remove embolic particles as they are cut from the inner wall of the artery. A balloon inflatable through a third lumen may be applied proximally as a protection against possible perforation of the artery.
