Abstract

Implantable frames for use in body passages are provided herein. The implantable frames can include a plurality of hoop members joined by a plurality of longitudinal connecting members to form a tubular frame defining a cylindrical lumen. The plurality of longitudinal connecting members may include first and second longitudinal connecting members joining a first hoop member to a second hoop member such that the first and second longitudinal connecting members extend across an entire space separating the first and second hoop members.

Claims

1. An implantable frame defining a lumen extending between a proximal end and a distal end along a longitudinal axis, the implantable frame moveable between a compressed state and an expanded state and comprising:

a proximal hoop member;

a distal hoop member;

each hoop member comprising a plurality of interconnected struts and bends arranged in an undulating shape;

a closely-spaced pair of longitudinal connecting members connecting the proximal hoop member to the distal hoop member, the closely-spaced pair of longitudinal connecting members comprising a first longitudinal connecting member and a second longitudinal connecting member; and

a structural member extending from the first longitudinal connecting member to the second longitudinal connecting member.

2. The implantable frame of claim 1, wherein the structural member comprises a circumferential reinforcing member.

3. The implantable frame of claim 1, further comprising a second structural member extending from the first longitudinal connecting member to the second longitudinal connecting member.

4. The implantable frame of claim 3, wherein the second structural member comprises a circumferential reinforcing member.

5. The implantable frame of claim 3, wherein each of the first and second structural members comprises a circumferential reinforcing member.

6. The implantable frame of claim 5, wherein the circumferential reinforcing members are parallel to each other.

7. The implantable frame of claim 1, further comprising a longitudinal attachment member disposed between the first and second longitudinal connecting members.

8. The implantable frame of claim 1, wherein the first closely-spaced pair of longitudinal connecting members extends from a first bend of a first hoop member toward a first bend of a second hoop member.

9. The implantable frame of claim 1, further comprising a radiopaque marker.

10. The implantable frame of claim 9, wherein the radiopaque marker is attached to a bridging member extending between first and second struts of a hoop member.

11. The implantable frame of claim 1, wherein the implantable frame is self-expandable.

12. The implantable frame of claim 1, wherein the implantable frame requires mechanical expansion to move from the compressed state to the expanded state.

13. The implantable frame of claim 1, wherein the implantable frame comprises stainless steel.

14. The implantable frame of claim 1, wherein the implantable frame comprises a shape memory alloy.

15. The implantable frame of claim 14, wherein the shape memory alloy comprises a Nickel-Titanium alloy.

16. The implantable frame of claim 1, wherein the implantable frame comprises a polymer.

17. The implantable frame of claim 1, wherein the implantable frame comprises a bioabsorbable polymer.

18. The implantable frame of claim 1, wherein the implantable frame includes a bioactive agent.

19. An implantable frame defining a lumen extending between a proximal end and a distal end along a longitudinal axis, the implantable frame moveable between a compressed state and an expanded state and comprising:

a proximal hoop member;

a distal hoop member;

each hoop member comprising a plurality of interconnected struts and bends arranged in an undulating shape;

a closely-spaced pair of longitudinal connecting members connecting the proximal hoop member to the distal hoop member, the closely-spaced pair of longitudinal connecting members comprising a first longitudinal connecting member and a second longitudinal connecting member;

a first structural member extending from the first longitudinal connecting member to the second longitudinal connecting member; and

a second structural member extending from the first longitudinal connecting member to the second longitudinal connecting member;

wherein the implantable frame is self-expandable.

20. An implantable frame defining a lumen extending between a proximal end and a distal end along a longitudinal axis, the implantable frame moveable between a compressed state and an expanded state and comprising:

a proximal hoop member;

a distal hoop member;

each hoop member comprising a plurality of interconnected struts and bends arranged in an undulating shape;

a closely-spaced pair of longitudinal connecting members connecting the proximal hoop member to the distal hoop member, the closely-spaced pair of longitudinal connecting members comprising a first longitudinal connecting member and a second longitudinal connecting member;

a first circumferential reinforcing member extending from the first longitudinal connecting member to the second longitudinal connecting member; and

a second circumferential reinforcing member extending from the first longitudinal connecting member to the second longitudinal connecting member;

wherein the circumferential reinforcing members are parallel to each other; and

wherein the implantable frame is self-expandable.
