Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery by engaging the plaque with a dynamic disrupter; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said, location.
Claim 2
Independent Claim
116 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery by engaging the plaque with a dynamic disrupter; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said, location.
Claim 3
Independent Claim
111 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery using a dynamic wire guide; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to by contiguously adhered within said artery at said location.
Claim 4
Independent Claim
111 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery using a dynamic wire guide; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to by contiguously adhered within said artery at said location.
Claim 5
Independent Claim
120 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery by engaging the plaque with a bladeless instrument; withdrawing the bladeless instrument; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said location.
Claim 6
Independent Claim

A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery by engaging the plaque with a bladeless instrument; withdrawing the bladeless instrument; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said location.
Claim 7
Independent Claim
134 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery using a first instrument; after performance of the initially loosening step, removing plaque first from adherence to the arterial wall within a segment of an artery at which the loosening step took place and second from the artery through the small man-made passageway using a second instrument; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said location.
Claim 8
Independent Claim
134 words
A method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery using a first instrument; after performance of the initially loosening step, removing plaque first from adherence to the arterial wall within a segment of an artery at which the loosening step took place and second from the artery through the small man-made passageway using a second instrument; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said location.
Claim 9
Dependent Claim
114 words
A continuous method of restoring reduced or absent blood flow capacity to an artery in a patient, comprising the steps of: accessing to the artery through a small man-made passageway; initially loosening plaque from the artery using a dynamic bladeless instrument; removing plaque from within a segment of an artery at which the loosening step took place through the small man-made passageway; placing a vascular graft into the artery through the small man-made passageway; placing the graft at a location within and as an internal lining for the artery co-extensive at least in part with the segment, using another instrument; causing the vascular graft to be contiguously adhered within said artery at said location.
Claim 10
Dependent Claim
