Double-Walled Stent System
First Claim
1. A stent system for use within a body lumen, the system comprising:
- an interior stent component having a proximal end, a distal end, and a generally tubular cylindrical body defining a central flow lumen there through; and
an exterior stent component including a plurality of longitudinally-extending connectors, wherein the proximal and distal ends of the interior stent component are attached to the exterior stent component such that the longitudinally-extending connectors are radially positioned around the tubular body of the interior stent component,wherein when the stent system is in an expanded configuration the longitudinally-extending connectors of the exterior stent component are configured to bow radially outward against a vessel wall of the body lumen while the interior stent component remains radially positioned within the longitudinally-extending connectors.

Abstract
A double walled stent system particularly suited for treating abnormalities of the right ventricular outflow tract is disclosed having an exterior stent component and an interior stent component. The exterior stent component includes a plurality of longitudinally-extending connectors such as straight or sinusoidal bands. The interior stent component has a generally tubular cylindrical body and is centered within the exterior stent component. The stent system has a contracted delivery configuration and a radially expanded configuration for contacting the vessel wall. When deployed, the longitudinally-extending connectors of the exterior stent component come in contact with the vessel wall and fix the stent system to the treatment site. The interior stent component also radially expands but remains centered inside the exterior component and makes little to no contact with the vessel wall.

21. A stent system for use within a body lumen, the system comprising:
-
an interior stent component including a proximal portion and a distal portion; and an exterior stent component including a first set of longitudinally-extending connectors and a second set of longitudinally-extending connectors, wherein the first set of longitudinally-extending connectors are attached to the proximal portion of the interior stent component and the second set of longitudinally-extending connectors are attached to the distal section of the interior stent component such that the first and second sets of longitudinally-extending connectors are radially positioned around the first and second portions of the interior stent component, respectively, wherein the first and second sets of longitudinally-extending connectors of the exterior stent component are configured to bow radially outward against a vessel wall of the body lumen and the interior stent component is radially positioned within the longitudinally-extending connectors of the exterior stent component when the stent system is in an expanded configuration. - View Dependent Claims (22)

23. A stent system for use within a body lumen, the system comprising:
-
an interior stent component having a proximal end, a distal end, and a generally tubular cylindrical body defining a central flow lumen there through; and an exterior stent component including a proximal stent strut, a distal stent strut and an intermediate stent strut, wherein the proximal stent strut is joined via a first set of longitudinally-extending connectors to the intermediate stent section and the distal stent strut is joined to the intermediate stent section by a second set of longitudinally-extending connectors, wherein the proximal end of the interior stent component is attached to the proximal stent strut of the exterior stent component and the distal end of the interior stent component is attached to the distal stent strut of the exterior stent component, such that the interior stent component is longitudinally positioned between the proximal and distal stent struts of the exterior stent component and radially positioned within the longitudinally-extending connectors and the intermediate stent strut of the exterior stent component. - View Dependent Claims (24, 25)
