Abstract
An endarterectomy device configured to remove plaque from an occluded artery is disclosed. The endarterectomy device uses an adjustable wire loop end effector to establish and advance a dissection plane in the subadventitial space of the artery. The endarterectomy device is passed down the length of an artery in the subadventitial plane, adjusting the size of the wire loop end effector as needed to navigate the artery and dissect a plaque column, until the end of the plaque is reached. The wire loop end effector is then used as a plaque cutter to transect the distal end of the plaque column. The endarterectomy device is further configured along its length with support arms that facilitate removal of the plaque column as the device is removed from the artery.
