Abstract
An atherectomy device having a housing at the distal end of a catheter adapted for insertion into the vascular system. The housing has a cutout in one side, and a cutter that is mounted in the housing for both axial and rotary movement with respect to the cutout. At least a portion of the housing is formed of a material which permits bending of the housing as it follows the contours of the vessel. The housing is also adapted to retain the severed atheroma materials.
