Abstract
Abstract An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The tubular body has a sufficiently small outside diameter and sufficient kink resistance and pushability to navigate through arteries such as the internal carotid artery.
