Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A minimally invasive method of lining a vessel of a medical patient to alleviate reduced blood flow, comprising the steps of: removing plaque through a small arteriotomy which was obtained from an arterial segment remote from the small arteriotomy; immediately thereafter grabbing a tubular vascular graft with a clamping device without materially altering a lengthwise dimension of the graft; forthwith introducing the tubular vascular graft into the vessel through the small arteriotomy under control of the clamping device; immediately thereafter placing the tubular vascular graft within the vessel at the plaque removal site under control of the clamping device; promptly causing adherence between the tubular vascular graft along the entire length of the graft and a theretofore unexposed interior surface of the vessel where plaque was removed, free of the clamping device.
Claim 2
Dependent Claim
132 words
A minimally invasive method of lining a vessel of a medical patient to alleviate reduced blood flow, comprising the steps of: removing plaque through a small arteriotomy which was obtained from an arterial segment remote from the small arteriotomy; immediately thereafter grabbing a tubular vascular graft with a clamping device without materially altering a lengthwise dimension of the graft; forthwith introducing the tubular vascular graft into the vessel through the small arteriotomy under control of the clamping device; immediately thereafter placing the tubular vascular graft within the vessel at the plaque removal site under control of the clamping device; promptly causing adherence between the tubular vascular graft along the entire length of the graft and a theretofore unexposed interior surface of the vessel where plaque was removed, free of the clamping device.
Claim 3
Dependent Claim
19 words
A minimally invasive method according to claim 1 further comprising surgically closing the arteriotomy after the promptly causing step.
Claim 4
Dependent Claim
84 words
A largely non-invasive method of lining a vessel of a medical patient, comprising the steps of: enlarging the flow path size of a segment of a vessel by removing plaque; without delay placing a vascular lining at a location within the vessel at the plaque removal segment under control of an instrument by which the lining is forcibly engaged; promptly thereafter permanently attaching the vascular lining without any tether entirely continuously to the inside of the vessel at said location separate from the instrument.
Claim 5
Dependent Claim
84 words
A largely non-invasive method of lining a vessel of a medical patient, comprising the steps of: enlarging the flow path size of a segment of a vessel by removing plaque; without delay placing a vascular lining at a location within the vessel at the plaque removal segment under control of an instrument by which the lining is forcibly engaged; promptly thereafter permanently attaching the vascular lining without any tether entirely continuously to the inside of the vessel at said location separate from the instrument.
Claim 6
Independent Claim
94 words
A method of lining a vessel of a medical patient, 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, under control of a lining-gripping device which does not stretch the vascular lining, at a location within the vessel which includes the treated portion; without material delay, securing the vascular lining untethered to the inside of the vessel as a long-term contiguous covering at said location free from the gripping device.
Claim 7
Independent Claim
94 words
A method of lining a vessel of a medical patient, 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, under control of a lining-gripping device which does not stretch the vascular lining, at a location within the vessel which includes the treated portion; without material delay, securing the vascular lining untethered to the inside of the vessel as a long-term contiguous covering at said location free from the gripping device.
Claim 8
Dependent Claim
83 words
A minimally invasive method of lining a vessel of a medical patient, comprising the steps of: treating the flow path interior of a vessel, the treating step comprising removing plaque; promptly thereafter placing a tubular vascular lining, under control of a lining-coupling device, at a location within the vessel at the segment; promptly thereafter attaching the tubular vascular lining continuously along its entire length to the inside surface within the vessel as a permanent covering at said location, free from the coupling device.
Claim 9
Dependent Claim
83 words
A minimally invasive method of lining a vessel of a medical patient, comprising the steps of: treating the flow path interior of a vessel, the treating step comprising removing plaque; promptly thereafter placing a tubular vascular lining, under control of a lining-coupling device, at a location within the vessel at the segment; promptly thereafter attaching the tubular vascular lining continuously along its entire length to the inside surface within the vessel as a permanent covering at said location, free from the coupling device.
