Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 87 words
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.
Claim 2
Independent Claim 87 words
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.
Claim 3
Independent Claim 102 words
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.
Claim 4
Independent Claim 102 words
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.
Claim 5
Independent Claim 85 words
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.
Claim 6
Independent Claim 85 words
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.
Claim 7
Independent Claim 84 words
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.
Claim 8
Independent Claim 84 words
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.
