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.

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;
- and
- 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.
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;
- 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.
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;
- wherein the one or more base members connect the one or plurality of struts to the rod;
- 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.
