Micro-thin film structures for cardiovascular indications
First Claim
1. A prosthetic liner comprising at least one elongate ribbon configured to form a first tubular structure, the ribbon being formed of a thin, narrow strand shaped to create the elongate ribbon such that the elongate ribbon has a width wider than a width of the thin, narrow strand, said elongate ribbon having a length that is longer than a length of the prosthetic liner.

Abstract
A thin lining for use within a body lumen having a variety of uses and particularly suited for protecting the intimal lining of a vessel, thereby preventing the release of embolic materials through the intima and into the bloodstream, either naturally or during the implantation of a prosthetic device. The thin lining is porous enough to promote ingrowth and thin enough to avoid migration with minimal radial force being placed on the vessel walls, making the lining also suited for applications such as blocking the entrance to an aneurysm.

11. A prosthetic liner comprising:
-
a plurality of rings, each of said rings being formed of a material having a thickness of between 0.00015 inches and 0.002 inches;
wherein said rings are arranged concentrically and connected together to form a tubular structure;
wherein the concentric rings are arranged such that, when the tubular structure is straight, the rings do not overlap each other. - View Dependent Claims (12, 13)

14. A method of protecting the intima of a vascular site comprising:
-
lining the intima with a thin tubular structure thin enough to reside within a boundary layer the blood stream, thereby preventing migration of the thin tubular structure while obviating a need for placing significant radial force on the intima;
promoting ingrowth of tissue into the thin tubular structure. - View Dependent Claims (15, 16)

17. A method of preventing fluid from entering a luminal aneurysm comprising:
-
lining a lumen with a thin tubular structure thin enough to reside within a boundary layer the blood stream, thereby preventing migration of the thin tubular structure while obviating a need for placing significant radial force on the intima, said thin tubular structure being positioned to cover an opening of an aneurysm;
promoting ingrowth of tissue into the thin tubular structure. - View Dependent Claims (18, 19, 20)
