Abstract
A method of restoring lost blood flow capacity to an artery is disclosed. The artery is enlarged by enlarging the flow path of a plaque-ridden segment of the artery using a plaque-removing instrument. The instrument is introduced through a small arteriotomy located remote from the segment. Next, a vascular lining is inserted through the small arteriotomy to a position co-extensive with the segment where the lining is secured.
Claims12
A low invasive method of restoring lost blood flow capacity to an artery of a medical patient, comprising the steps of:
- enlarging the flow path size of a plaque-ridden segment of an artery using a plaquere-moving instrument introduced through a small arteriotomy located remote from the segment;
- clamping a vascular lining to a clamping instrument such that the lining is compressively secured by the clamping instrument and at least a substantial portion of an exterior surface of the lining is exposed apart from the clamping instrument;
- thereafter jointly inserting the exposed lining and the clamping instrument into the artery through the remote small arteriotomy and thence to a position at least in part co-extensive with a portion of the segment;
- securing the vascular lining within said artery at said position.
A low invasive method of restoring lost blood flow capacity to an artery of a medical patient, comprising the steps of:
- providing a small access passageway into the artery;
- enlarging the flow path size of a plaque-ridden segment of the artery comprising axially cutting longitudinally away from the passageway and removing both plaque and a portion of the interior of the artery through the passageway;
- placing a vascular lining into the artery through the passageway to a location at least in part co-extensive with a portion of the segment;
- securing the vascular lining within said artery at said location.
