Abstract

Methods of artificially lining a vessel, especially an artery, of a medical patient to address the existence of a flow-inhibiting atheroma and to significantly alleviate the probability of restenosis, and the resulting products.

Claims

1. A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of:

excavating plaque and the like from within a segment of an artery;

placing a vascular graft at a location within and as an internal lining for the artery at least co-extensive with the excavated segment by displacing the vascular graft through the surgical access site using a forceps to grasp a distal end of the vascular graft;

securing the vascular graft within said artery at said location.

2. A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of:

excavating plaque and the like from within a segment of an artery;

placing a vascular graft at a location within and as an internal lining for the artery at least co-extensive with the excavated segment by suturing a distal end of the vascular graft to a mandrel, advancing the mandrel and the vascular graft collectively into the artery, unsuturing the vascular graft from the mandrel and removing the mandrel from the artery;

securing the vascular graft within said artery at said location.

3. A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of:

excavating plaque and the like from within th segment of an artery;

placing a vascular graft at a location within and as an internal lining for the artery at last co-extensive with the excavated segment by displacing the vascular graft through the surgical access site using a grasping instrument to releasibly grasp the vascular graft;

securing the vascular graft within said artery at said location.

4. A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of:

excavating plaque and the like from within a segment of an artery;

placing a vascular graft at a location within and as an internal lining for the artery at least co-extensive with the excavated segment by displacing the vascular graft through the surgical access site by releasibly clamping an insertion device to the graft;

securing the vascular graft within said artery at said location.
