Flexible stent with hinged connectors

1. A composite implantable prosthesis, comprising:

a scaffold including a first section distributed axially along and circumscribing a longitudinal axis and including a second section distributed axially along and circumscribing the longitudinal axis wherein the sections define a cylindrical moiety, the sections comprise an axially protruding pin and an elastic material;

one or more bridges including at least one interior hinge and at least one boss; and

a joint between the first section and the second section comprising the pin disposed within the boss.

2. The composite implantable prosthesis according to claim 1 , wherein the first material is one or more of stainless steel, shape memory metals, shape memory alloys, super elastic shape memory metal alloys, metal alloys, linear elastic shape memory alloys, Nitinols, cobalt chrome alloys.

3. The composite implantable prosthesis according to claim 2 , wherein the second material is a polymer, and wherein long polymer molecules of the second material form the at least one hinge and are aligned across a width of the hinge.

4. The composite implantable prosthesis according to claim 2 , further comprising a first generally tubular polymer member comprising ePTFE disposed along an inner surface of the scaffold, and a second generally tubular polymer member comprising ePTFE disposed along an outer surface of the scaffold, wherein the second generally tubular polymer member is bonded to the first generally tubular polymer member through openings in the scaffold.

5. The composite implantable prosthesis according to claim 2 , wherein the second material is a bioabsorbable polymer.

6. The composite implantable prosthesis according to claim 5 , wherein the at least one hinge comprises a plurality of hinges that are linearly arranged along a length of the bridge.

7. The composite implantable prosthesis according to claim 6 , wherein the at least one hinge is integrally formed in the bridge.

8. The composite implantable prosthesis according to claim 7 , wherein two or more bridges connect adjacent circumferential sections, the bridges circumferentially spaced apart about the longitudinal axis.

9. The composite implantable prosthesis according to claim 8 , wherein at least one of the bridges includes multiple rows of bridge sections interconnected by hinges.

10. The composite implantable prosthesis according to claim 5 , wherein the first material extends across only a limited portion of the spaced apart distance.

11. The composite implantable prosthesis of claim 5 wherein the scaffold comprises one or more elongate members helically wound about the longitudinal axis, each of the circumferential sections formed by one or more helical windings.

12. The composite implantable prosthesis of claim 11 wherein the first and second sections comprises a single continuous elongate member.

13. The composite implantable prosthesis of claim 5 wherein the circumferential sections comprise distinct rings.

14. The composite implantable prosthesis of claim 5 wherein the boss is disposed over a substantial length of the pin.

15. The composite implantable prosthesis of claim 14 wherein the pin includes an enlarged distal end.

16. The composite implantable prosthesis according to claim 1 , wherein at least one circumferential section has a different shape, size, or configuration than an adjacent circumferential section.

17. The composite implantable prosthesis according to claim 1 , wherein the at least one hinge is oriented to permit a bridge to pivot around a first axis that is tangential to the circumference of a surface of the implantable prosthesis, and an adjacent hinge on the same bridge is oriented ninety degrees from the at least one hinge to permit rotation around a second axis perpendicular to the first axis, wherein the at least one hinge resists pivoting around the second axis and the adjacent hinge resists pivoting around the first axis.
