Abstract
An atherectomy device for cutting obstructive tissue from the lumen of a body vessel comprises a rotatable cutter having a blade. A hollow, generally cylindrical housing defines a central longitudinal axis and has a side opening. The cutter is mounted in the housing for rotation about an axis that is substantially parallel to the longitudinal axis of the housing. During rotation of the cutter, the blade cyclically projects from the side opening to cut obstructive tissue from the lumen.
