Abstract
A bilateral intra-aortic bypass graft and method and apparatus for repairing an abdominal aortic aneurysm includes two tubular grafts which are intraluminally delivered to the aorta and secured to the aorta by the expansion and deformation of two expandable and deformable tubular members.
Claims (7)
1. A graft for intraluminal delivery into a body passageway comprising:
an elongate tube having first and second ends and formed of a plurality of expandable and deformable first tubular members, each first tubular member having a longitudinal axis, the plurality of first tubular members being aligned with their longitudinal axes being substantially parallel with each other, each first tubular member being spaced apart from adjacent tubular members and the plurality of first tubular members being embedded within a layer of a deformable and expandable plastic material, each first tubular member having a first diameter which permits intraluminal delivery of the tube into the body passageway and a second, expanded and deformed diameter, upon the application from the interior of the first tubular member of a radially, outwardly extending force, the second diameter being variable and dependent upon the amount of force applied to the first tubular member, each first tubular member being able to substantially maintain the second, expanded and deformed diameter after the removal of said radially outwardly extending force; and means for securing the first end of the tube within a body passageway, the securing means being a second expandable and deformable tubular member having first and second ends, the first end of the tube being connected to the second end of the second tubular member by embedding a portion of the second end of the second tubular member in the layer of the deformable and expandable plastic material of the tube, with the first end of the second tubular member being exposed for direct contact with the body passageway and disposed outside the layer of deformable and expandable plastic material, the second tubular member having a first diameter which permits intraluminal delivery of the second tubular member and tube into the body passageway and the second tubular member having a second, expanded and deformed diameter, upon the application from the interior of the second tubular member of a radially, outwardly extending force, the second diameter being variable and dependent upon the amount of force applied to the second tubular member, the second tubular member being able to substantially maintain the second, expanded and deformed diameter after the removal of said radially outwardly extending force, whereby the second tubular member may be expanded and deformed to secure the first end of the second tubular member within the body passageway.
an elongate tube having first and second ends and formed of a plurality of expandable and deformable first tubular members, each first tubular member having a longitudinal axis, the plurality of first tubular members being aligned with their longitudinal axes being substantially parallel with each other, each first tubular member being spaced apart from adjacent tubular members and the plurality of first tubular members being embedded within a layer of a deformable and expandable plastic material, each first tubular member having a first diameter which permits intraluminal delivery of the tube into the body passageway and a second, expanded and deformed diameter, upon the application from the interior of the first tubular member of a radially, outwardly extending force, the second diameter being variable and dependent upon the amount of force applied to the first tubular member, each first tubular member being able to substantially maintain the second, expanded and deformed diameter after the removal of said radially outwardly extending force; and means for securing the first end of the tube within a body passageway, the securing means being a second expandable and deformable tubular member having first and second ends, the first end of the tube being connected to the second end of the second tubular member by embedding a portion of the second end of the second tubular member in the layer of the deformable and expandable plastic material of the tube, with the first end of the second tubular member being exposed for direct contact with the body passageway and disposed outside the layer of deformable and expandable plastic material, the second tubular member having a first diameter which permits intraluminal delivery of the second tubular member and tube into the body passageway and the second tubular member having a second, expanded and deformed diameter, upon the application from the interior of the second tubular member of a radially, outwardly extending force, the second diameter being variable and dependent upon the amount of force applied to the second tubular member, the second tubular member being able to substantially maintain the second, expanded and deformed diameter after the removal of said radially outwardly extending force, whereby the second tubular member may be expanded and deformed to secure the first end of the second tubular member within the body passageway.
2. The graft of claim 1, wherein the plastic material is silicone.
3. The graft of claim 1, wherein the plastic material is polytetrafluoroethylene.
4. The graft of claim 3, wherein the plastic material is expanded polytetrafluoroethylene.
5. The graft of claim 1, wherein the plastic material is expanded polyurethane.
6. The graft of claim 1, wherein a single flexible connector member is disposed between the adjacent tubular members of the plurality of first tubular members which form the tube.
7. The graft of claim 1, wherein the plastic material of the tube is a synthetic polyester material.
