Abstract
A catheter includes an elongate catheter body configured for insertion into a body lumen of a subject. A cutter is located generally at a distal end of the catheter body for rotation generally about a longitudinal axis of the cutter. An eccentric opening in a distal end portion of the cutter defines an angled cutting edge for cutting material from a wall of the body lumen. A center of the opening is offset from the longitudinal axis of the cutter. A cavity extends from the opening through the cutter from the distal end portion to a proximal end portion to allow material cut by the cutter to pass through the cutter into an interior passage of the catheter body for removal from the body lumen.
