METHOD AND APPARATUS FOR TREATING A CAROTID ARTERY
First Claim
Patent Images
1. A system for use in treating a carotid artery, comprising:
- an arterial access device adapted to be introduced into a common carotid artery, the arterial access device having a lumen for receiving retrograde blood flow from the common carotid artery;
a shunt fluidly connected to the arterial access device, wherein the shunt provides a pathway for blood to flow out of the arterial access device; and
a flow control mechanism coupled to the shunt and adapted to control blood flow through the shunt.

Abstract
One disclosed embodiment comprises a method for treating lesions in the carotid artery of a mammalian body. The method comprises transcervical access and blocking of blood flow through the common carotid artery (with or without blocking of blood flow through the external carotid artery), shunting blood from the internal carotid artery and treating the lesion in the carotid artery.

14. A method for accessing an internal carotid artery, comprising:
-
positioning an arterial access device in a common carotid artery via a transcervical approach; establishing retrograde blood flow through the common carotid artery such that blood flows into a lumen of the arterial access device and into a shunt connected to the arterial access device; and controlling the flow of blood through the shunt. - View Dependent Claims (15, 16, 17, 18)
