Abstract
The disclosure provides various embodiments of prostheses and delivery systems to permit an interventional cardiologist to create shunts between various blood vessels. Moreover, the disclosed shunts can be used to shunt between various hollow organs, as set forth in the present disclosure.
Claims19
A prosthesis having a proximal end, a distal end, and defining an axial direction from the proximal end to the distal end, the prosthesis comprising:
- a proximal sealing flange configured and arranged to facilitate seating a proximal end portion of the prosthesis against an interior concave surface of a wall of a first vessel, wherein the prosthesis is configured to extend outwardly through an ostium formed through the wall of the first vessel when deployed, wherein the proximal sealing flange remains inside the ostium after deployment;
- a distal sealing flange displaceable from the proximal sealing flange along the axial direction, the distal sealing flange being configured and arranged to facilitate seating a distal end portion of the prosthesis against an interior concave surface of a wall of a second vessel, wherein the prosthesis is configured to extend outwardly through an ostium formed through the wall of the second vessel when deployed, wherein the distal sealing flange remains inside the ostium after deployment;
- and
- a first circumferential undulating strut ring formed from a first undulating filament disposed axially between the proximal sealing flange and the distal sealing flange;
- a second circumferential undulating strut ring formed from a second undulating filament disposed axially between the proximal sealing flange and the distal sealing flange, the filament of the second circumferential undulating strut ring being woven and wrapped around the filament of the first circumferential undulating strut ring about a circumference of the prosthesis, wherein the filament of the first circumferential undulating strut ring and the filament of the second circumferential undulating strut ring are configured to slide over each other along the axial direction to permit the prosthesis to collapse along the axial direction into a nested configuration.

- a plurality of undulating circumferential strut rings disposed axially between the proximal sealing flange and the distal sealing flange;
- and
- at least one tension coil spring connecting the proximal sealing flange to the distal sealing flange to cause the prosthesis to collapse into an axially shortened configuration, the at least one tension coil spring being disposed along an axial direction alongside and radially displaced with respect to each of the plurality of undulating strut rings.
