Patent Images
1. A method of treating a lesion in a carotid artery of a patient having an arterial blood system and a venous blood system, comprising:
- making a transcervical incision to expose a region of a common carotid artery;
positioning an arterial access device in the common carotid artery through the transcervical incision, wherein the arterial access device comprises a distal insertable length;
occluding blood flow in at least a portion of the common carotid artery;
shunting blood from the common carotid artery to the venous system of the patient via the arterial access device; and
treating the lesion by deploying a stent on the lesion.

- 14. The method of claim 14, further comprising filtering the blood from the common carotid artery prior to shunting the blood to the venous system using a filter.
-
17. The method of claim 17, wherein the anchor element further occludes blood flow in the at least a portion of the common carotid artery.
-
19. The method of claim 19, wherein the at least a portion of the distal insertable length is generally rigid but sufficiently malleable to maintain the bent shape during positioning in the common carotid artery.
-
24. The method of claim 24, further comprising removing the arterial access device from the common carotid artery and repairing the arterial puncture.
