Abstract
Abstract A method for endoluminally treating a pathological defect is disclosed. The method comprises the steps of introducing first and second graftstents through respective first and second access sites on a first side of a pathological defect; advancing the graftstents until each extends across the defect and is positioned within a common body passageway on a second side of the pathological defect; and drawing the graftstents together within the common body passageway.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
128 words
A method for endoluminally treating a pathological defect within or part of a body passageway of a patient, there being healthy tissue on a first side and on a second side of the pathological defect and the pathological defect being positioned in the vicinity of a branching passageway within a patient, comprising the steps of: (a) introducing first and second graftstents through respective first and second access sites, the first and second access sites being on the first side of the pathological defect; (b) advancing the first and second graftstents until each extends across the pathological defect and is positioned in a common body passageway and on the second side of the pathological defect; and (c) drawing the first and second graftstents together within the common body passageway.
Claim 2
Independent Claim
128 words
A method for endoluminally treating a pathological defect within or part of a body passageway of a patient, there being healthy tissue on a first side and on a second side of the pathological defect and the pathological defect being positioned in the vicinity of a branching passageway within a patient, comprising the steps of: (a) introducing first and second graftstents through respective first and second access sites, the first and second access sites being on the first side of the pathological defect; (b) advancing the first and second graftstents until each extends across the pathological defect and is positioned in a common body passageway and on the second side of the pathological defect; and (c) drawing the first and second graftstents together within the common body passageway.
Claim 3
Dependent Claim
19 words
The method as in claim 1, wherein the drawing step comprises endoluminally tying the first and second graftstents together.
Claim 4
Dependent Claim
36 words
The method as in claim 1, including the additional step of affixing one end of an anchor line to the first graftstent prior to the step of introducing the first graftstent through the first access site.
Claim 5
Dependent Claim
24 words
The method as in claim 3, including the additional step of drawing a second end of the anchor line through the second access site.
Claim 6
Dependent Claim
33 words
The method as in claim 4, including the additional step of threadedly coupling the second graftstent to the anchor line prior to the step of introducing the second graftstent through second access site.
Claim 7
Dependent Claim
45 words
The method as in claim 5, wherein the step of drawing the first and second graftstents includes the step of advancing one of a knot and an anchor bead over the second end of the anchor line to the second side of the pathological defect.
Claim 8
Dependent Claim
40 words
The method as in claim 6, including the additional step of rotationally aligning the first and second graftstents by reducing the length of anchor line extending between the first and second graftstents at the second side of the pathological defect.
Claim 9
Dependent Claim
56 words
The method as in claim 3, wherein there are plural anchor lines each having one end and a second end and wherein the affixing step includes affixing said one end of the plural anchor lines to the first graftstent, and wherein said second end of the plural anchor lines are drawn through the second access site.
Claim 10
Dependent Claim
41 words
he method as in claim 8, including the additional step of threadedly coupling said second ends of each of the plural anchor lines to the second graftstent prior to the step of introducing the second graftstent through the second access site.
Claim 11
Dependent Claim
48 words
The method as in claim 9, wherein the step of drawing the first and second graftstents includes the step of advancing one of a knot and an anchor bead over each of the second ends of the plural anchor lines to the second side of the pathological defect.
Claim 12
Dependent Claim
36 words
The method as in claim 1, wherein the stents of the first and second graftstents include preset bows which substantially mate upon joining the first and second graftstents on the second side of the pathological defect.
Claim 13
Dependent Claim
20 words
The method as in claim 1, wherein the drawing step comprises drawing a cephalic portion of the two graftstents together.
Claim 14
Dependent Claim
36 words
The method as in claim 1, including the additional step of affixing the first and second graftstents within the common body passageway on the second side of the pathological defect whereby the pathological defect is excluded.
