Abstract

A valve comprising: (a) a rod, (b) a plurality of struts in communication with the rod and extending generally radially outward away from the rod in a deployed state, the plurality of struts including at least: (i) a plurality of first struts that extend radially outward from the rod a first distance, and (ii) a plurality of second struts that extend radially outward a second distance from the rod, wherein the second distance is less than the first distance; and (c) one or more membranes that are in communication with the first struts, the second struts, or both.

Claims

1. ) A valve comprising:

a. a rod,

b. a plurality of struts in communication with the rod and extending generally radially outward away from the rod in a deployed state, the plurality of struts including at least;

i. a plurality of first struts that extend radially outward from the rod a first distance, and

ii. a plurality of second struts that extend radially outward a second distance from the rod, wherein the second distance is less than the first distance; and

c. one or more membranes that are in communication with the first struts, the second struts, or both.

2. ) The valve of claim 1, wherein one of the one or more membranes are in communication with the plurality of first struts, and a second of the one or more membranes is in communication with the plurality of second struts.

3. ) The valve of claim 1, wherein the plurality of second struts are free of the one or more membranes.

4. ) The valve of claim 1, wherein the plurality of second struts support the one or more membranes when the plurality of first struts are compressed so that the one or more membranes are moved into contact with a structure and the valve forms a seal with the structure.

5. ) The valve of claim 1, wherein the valve includes a distal end and a proximal end and the plurality of second struts are in communication with the rod at a location closer to the proximal end than the plurality of first struts are in communication with the rod.

6. ) The valve of claim 1, wherein the plurality of second struts and the plurality of first struts all have a length and the length of the plurality of first struts is equal to or less than the length of the plurality of second struts.

7. ) The valve of claim 1, wherein the plurality of first struts and the plurality of second struts are aligned.

8. ) The valve of claim 1, wherein the plurality of first struts and the plurality of second struts are offset relative to each other.

9. ) The valve of claim 1, wherein one or more base members connect the plurality of struts to the rod.

10. ) The valve of claim 9, wherein the plurality of first struts are connected to one of the one or more base members, and the plurality of second struts are connected to a second of the one or more base members.

11. ) The valve of claim 9, wherein the one or more base members are a single base member and both the plurality of second struts and the plurality of first struts are connected to the single base member.

12. ) The valve of claim 1, wherein the valve has a valve section and an anchor section.

13. ) The valve of claim 12, wherein the valve section and the anchor section are one unitary piece.

14. ) The valve of claim 12, wherein the valve section and the anchor section are connected by a hinge point.

15. ) The valve of claim 14, wherein the hinge point includes a pair of interconnects connected together.

16. ) The valve of claim 14, wherein the hinge point is a ball and socket connected together.

17. ) The valve of claim 14, wherein the hinge point is a coil spring.

18. ) The valve of claim 1, wherein the membrane has a modulus of elasticity of between about 0.0100 GPa to about 0.0200 GPa

19. ) The valve of claim 1, wherein at least one of the materials of the membrane is silicone.
