Abstract
An atherectomy system for cutting, ingesting and removing an obstruction from within a patient's artery, having a flexible guide-wire insertable into the artery, a flexible rotary catheter being rotatably disposed and insertable into the artery over the flexible guide-wire, a blade at a distal end of the flexible rotary catheter having teeth on its periphery which are rounded and bent toward the center of the blade to ease insertion through the arteries and to reduce the probability of cutting the arterial wall during the insertion and cutting operation the blade having an outer wall which slidingly and rotatably bears against the arterial wall spreading the contact force on a relatively large area to minimize damage to the artery, a continuous passage defined between the rotating flexible rotary catheter and the flexible guide-wire, for ingesting the cut obstruction material.
