Abstract: An endarterectomy catheter and method for removing obstructions from an artery comprises a cylindrical, oval, kidney shaped or other shape housing, the housing having an opening inside which a primary shear is movable. The primary shear is razor sharp and cylindrical or other shaped with a smooth or serrated or threaded finish on the inner diameter and movable by means of a firing wire connected by an adapter to a trigger mechanism, which moves the primary shear backward and forward within the housing to excise, encapsulate and store obstructions that protrude into the opening. The primary shear can also be moved by an electric wire and solenoid, hydraulic system or other means. A guide wire positions the catheter in an artery fallopian tube or other lumen and an inflatable saline anchor or anchors stabilize the catheter against the obstruction to execute a precise cut.
