Abstract
The invention provides a method for augmenting circulation in a patient having carotid stenosis. An elongate tubular member is provided having a lumen communicating with a port at a distal end. The tubular member is inserted into a peripheral artery and the distal port is advanced into a first carotid artery substantially free of a lesion where the patient possesses a second carotid artery substantially occluded by a lesion. Blood is perfused into the first carotid artery through the tubular member. Contralateral flow is augmented to improve perfusion to an ischemic region distal to the carotid stenosis. Angioplasty and stenting can be used to open the lesion in the second carotid artery.
Claims18
A method for augmenting circulation in a patient having a vascular lesion, comprising the steps of:
- providing an elongate tubular member having a lumen communicating with a port at a distal end;
- inserting the tubular member into a peripheral artery and advancing the distal port into a first cerebral or carotid artery substantially free of a lesion, wherein the patient possesses a second cerebral or carotid artery substantially occluded by a lesion;
- and
- perfusing blood into the first cerebral or carotid artery through the tubular member, wherein contralateral flow is augmented to improve perfusion to an ischemic region distal to the lesion by retrograde blood flow within the second cerebral or carotid artery.
