Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 56 words
A method of treating an artery, comprising the steps of: removing plaque and the like from within a segment of an artery; placing an essentially non-disintegrating vascular graft at a location within and as an internal lining for the artery at least co-extensive with the segment; securing the vascular graft within said artery at said location.
Claim 2
Independent Claim 56 words
A method of treating an artery, comprising the steps of: removing plaque and the like from within a segment of an artery; placing an essentially non-disintegrating vascular graft at a location within and as an internal lining for the artery at least co-extensive with the segment; securing the vascular graft within said artery at said location.
Claim 3
Dependent Claim 55 words
A continuous method of treating an artery, comprising the steps of: separating material comprising plaque from other material within a segment of an artery; placing a predominantly solid vascular graft at a location within the artery comprising the separating site; securing the vascular graft as a permanent lining within said artery at the placing site.
Claim 4
Dependent Claim 55 words
A continuous method of treating an artery, comprising the steps of: separating material comprising plaque from other material within a segment of an artery; placing a predominantly solid vascular graft at a location within the artery comprising the separating site; securing the vascular graft as a permanent lining within said artery at the placing site.
Claim 5
Independent Claim 63 words
A method of enlarging a lumen in an artery comprising the steps of: parting first material from second material in an arterial segment; immediately thereafter, placing a non-disintegrating vascular graft at least in part within the arterial segment generally in spaced relation thereto; immediately thereafter, placing the vascular graft generally contiguous with and connected to tissue comprising the arterial segment for non-disintegrating retention.
Claim 6
Independent Claim 63 words
A method of enlarging a lumen in an artery comprising the steps of: parting first material from second material in an arterial segment; immediately thereafter, placing a non-disintegrating vascular graft at least in part within the arterial segment generally in spaced relation thereto; immediately thereafter, placing the vascular graft generally contiguous with and connected to tissue comprising the arterial segment for non-disintegrating retention.
Claim 7
Independent Claim 94 words
A method of enlarging a lumen of an artery, comprising the steps of: eliminating at least some plaque from within a segment of an artery; placing a vascular graft, not previously in the artery, at a location within and as an internal lining for the artery at a location which substantially covers at least a portion of the segment by displacing the vascular graft through the surgical access site using a graft control; essentially permanently securing the vascular graft so that the graft is generally long term contiguous within said artery at said location.
Claim 8
Independent Claim 94 words
A method of enlarging a lumen of an artery, comprising the steps of: eliminating at least some plaque from within a segment of an artery; placing a vascular graft, not previously in the artery, at a location within and as an internal lining for the artery at a location which substantially covers at least a portion of the segment by displacing the vascular graft through the surgical access site using a graft control; essentially permanently securing the vascular graft so that the graft is generally long term contiguous within said artery at said location.
Claim 9
Independent Claim 95 words
A method of treating a vessel to enlarge a lumen thereof, comprising the steps of: removing plaque from the vessel; uniting a vascular graft, in a relatively small configuration, with a device; introducing the vascular graft into the interior of the vessel under control of the device; placing the vascular graft within the vessel at a predetermined internal site; releasing the graft from the control of the device; placing the graft in a relatively larger configuration; causing adherence between the released vascular graft and an interior surface within the vessel as a long term liner.
Claim 10
Independent Claim 95 words
A method of treating a vessel to enlarge a lumen thereof, comprising the steps of: removing plaque from the vessel; uniting a vascular graft, in a relatively small configuration, with a device; introducing the vascular graft into the interior of the vessel under control of the device; placing the vascular graft within the vessel at a predetermined internal site; releasing the graft from the control of the device; placing the graft in a relatively larger configuration; causing adherence between the released vascular graft and an interior surface within the vessel as a long term liner.
Claim 11
Dependent Claim 88 words
An on-going method of treating an artery, comprising the steps of: enlarging the flow path size of a plaque-ridden segment of an artery through an arteriotomy; releasibly combining a vascular lining and a control outside the artery after the enlarging step; jointly inserting the lining and the control into the artery through the arteriotomy to a position comprising at least part of the segment; expanding the diametral size of the lining while in said position; essentially permanently securing the expanded vascular lining within said artery at said location.
Claim 12
Dependent Claim 88 words
An on-going method of treating an artery, comprising the steps of: enlarging the flow path size of a plaque-ridden segment of an artery through an arteriotomy; releasibly combining a vascular lining and a control outside the artery after the enlarging step; jointly inserting the lining and the control into the artery through the arteriotomy to a position comprising at least part of the segment; expanding the diametral size of the lining while in said position; essentially permanently securing the expanded vascular lining within said artery at said location.
Claim 13
Independent Claim 77 words
A method of lining a vessel, comprising the steps of: treating the flow path interior of a portion of a vessel at a site where the vessel is not surgically open; without material delay, placing a tubular vascular lining, at a location within the vessel which includes the treated portion; without material delay, securing the vascular lining at an inside surface of the vessel so that the lining comprises a long-term generally contiguous covering at said location.
Claim 14
Independent Claim 77 words
A method of lining a vessel, comprising the steps of: treating the flow path interior of a portion of a vessel at a site where the vessel is not surgically open; without material delay, placing a tubular vascular lining, at a location within the vessel which includes the treated portion; without material delay, securing the vascular lining at an inside surface of the vessel so that the lining comprises a long-term generally contiguous covering at said location.
Claim 15
Dependent Claim 71 words
A combined unitary method of treatment of an artery, comprising the steps of: parting plaque from within a segment of an artery; removing plaque from the segment of the artery; immediately following the removing step, placing a vascular graft at a location within and as an internal lining for the artery co-extensive and covering at least in part with the segment; securing the vascular graft within said artery at said location.
Claim 16
Dependent Claim 71 words
A combined unitary method of treatment of an artery, comprising the steps of: parting plaque from within a segment of an artery; removing plaque from the segment of the artery; immediately following the removing step, placing a vascular graft at a location within and as an internal lining for the artery co-extensive and covering at least in part with the segment; securing the vascular graft within said artery at said location.
Claim 17
Dependent Claim 101 words
An uninterrupted method of lumen enlargement of an artery, comprising the steps of: treating plaque from within a segment of an artery using an instrument introduced through a man-made access site to the artery; removing the instrument from the artery through the access site; thereafter placing a vascular graft and a control for the graft jointly through the access site and at a location within the artery at least co-extensive with the segment; releasing the graft from the control and removing the control through the access site; securing the vascular graft within said artery at said location within the vascular graft.
Claim 18
Dependent Claim 101 words
An uninterrupted method of lumen enlargement of an artery, comprising the steps of: treating plaque from within a segment of an artery using an instrument introduced through a man-made access site to the artery; removing the instrument from the artery through the access site; thereafter placing a vascular graft and a control for the graft jointly through the access site and at a location within the artery at least co-extensive with the segment; releasing the graft from the control and removing the control through the access site; securing the vascular graft within said artery at said location within the vascular graft.
