Abstract

Implantable medical devices for connecting tissue layers or occluding body conduits and tissue structures include apposition portions, a central region, and a covering material. The methods of using the devices include endoscopic deployment, and the devices may include self-expanding frameworks that facilitate a secure connection between the tissue structures. In some embodiments, one or more tethers are used to longitudinally contract the device in situ.

Claims (28)

1. A medical device comprising:

a framework including one or more elongate members, the framework defining:

a first apposition portion;

a second apposition portion; and

a central portion positioned longitudinal between and interconnecting the first apposition portion and the second apposition portion, wherein the framework central portion comprises only a single elongate member that extends around a circumference of the central portion less than three times helically between the first apposition portion and the second apposition portion;

a covering material disposed on at least a portion of the framework.

2. The medical device of claim 1 , wherein the framework extending around the circumference of the central portion includes a serpentine shape when in an expanded configuration.

3. The medical device of claim 2 , wherein the framework extending around the circumference of the central portion includes sections that extend parallel to a longitudinal axis of the central portion when in a radially compressed configuration.

4. The medical device of claim 1 , wherein the framework extending around the circumference of the central portion includes about eight apices per circumference.

5. The medical device of claim 1 , wherein the framework extending around the circumference of the central portion includes a first elongate member of the one or more elongate members and one of the first and second apposition portions includes a second elongate member of the one or more elongate members.

6. The medical device of claim 5 , wherein the first elongate member includes differing properties than the second elongate member.

7. The medical device of claim 6 , wherein the differing properties are selected from one of diameter, stiffness, material composition, shape memory property, cross-sectional shape, geometry, and elasticity.

8. The medical device of claim 1 , wherein the majority of the covering material at the central portion is unsupported by the single elongate member.

9. The medical device of claim 1 , further comprising a tether extending from a first end to longitudinally collapse the central portion.

10. The medical device of claim 9 , wherein the tether is routed through the central portion.

11. The medical device of claim 9 , wherein the tether is routed through the central portion.

12. The medical device of claim 1 , wherein the majority of the covering material at the central portion is unsupported by the one or more elongate members.

13. The medical device of claim 1 , further comprising a tether extending from a first end to longitudinally collapse the central portion.

14. A medical device comprising:

a framework including one or more elongate members, the framework defining:

a first apposition portion;

a second apposition portion; and

a central portion positioned longitudinal between and interconnecting the first apposition portion and the second apposition portion, wherein the framework central portion comprises only a single elongate member extending around a circumference of the central portion helically between the first apposition portion and the second apposition portion and includes a serpentine shape when in an expanded configuration and wherein the framework extending around the circumference of the central portion includes sections that extend parallel to a longitudinal axis of the central portion when in a radially compressed configuration;

a covering material disposed on at least a portion of the framework.

15. The medical device of claim 14 , wherein the framework extending around the circumference of the central portion includes about eight apices per circumference.

16. The medical device of claim 14 , wherein the framework extending around the circumference of the central portion includes a first elongate member of the one or more elongate members and one of the first and second apposition portions includes a second elongate member of the one or more elongate members.

17. The medical device of claim 16 , wherein the first elongate member includes differing properties than the second elongate member.

18. The medical device of claim 17 , wherein the differing properties are selected from one of diameter, stiffness, material composition, shape memory property, cross-sectional shape, geometry, and elasticity.
