Embodiment Construction
[0071] The intravascular devices and methods of construction and use are described below. The present invention is described in connection with treating partial or total occlusions but may be used for any other suitable purpose. The general principles for treating partial and total occlusions within a patient's vasculature are described in connection with FIGS. 1A-1C. A blood vessel BV which is usually an artery, more usually a cerebral artery, such as a carotid artery, vertebral artery, or an intracerebral artery, is obstructed by a total occlusion TO. The occlusion may result from thrombosis at a pre-existing atherosclerotic lesion or may result from the shedding of an embolus from an artery which flows distally to the particular vessel in which the occlusion occurs. Usually, the occlusion will occur abruptly and the sudden loss of perfusion through the blood vessel distal to the total occlusion TO will place the patient at great risk of neuron death. As discussed above in the Bac...
