Abstract
An atherectomy device and method has cannula systems having lumens adapted for insertion of a blood filter and an atherectomy catheter useful for performing atherectomy directly on a patient's cardiovascular tissue. Other embodiments include a lumen for arterial perfusion useful in providing oxygenated blood to the aorta during cardiopulmonary bypass. The distal end of the atherectomy catheter includes an assembly that has a pincer, a loop with or without a mesh, laser, hydraulics, or other suitable mechanism adapted for removing atheroma from a cardiac or vascular tissue. Methods of using the systems for vascular atherectomy are also disclosed herein.
