The present invention relates generally to dynamic and/or adjustable support devices, methods of providing dynamic and/or adjustable support to target tissues, and kits comprising these devices. These devices may have particular utility in providing support to the urethra. The dynamic support devices generally comprise at least one attachment member for attachment to bodily tissue, and at least one expandable member capable of assuming an unexpanded configuration and an expanded configuration. The adjustable support devices generally comprise at least one attachment member for attachment to bodily tissue, and at least one shape-changing portion that is capable of assuming first and second configurations, each with different shapes. Additionally, the dynamic support devices may comprise features of the adjustable support devices, and vice versa.

1. A device for supporting a tissue, the device comprising: first and second flexible attachment members and at least one expandable member positioned therebetween, wherein the first and second attachment members each comprises a strip of flexible material, and wherein one or more of the attachment members comprises a mesh;wherein the expandable member has an unexpanded configuration and an expanded configuration;wherein the expandable member changes from its unexpanded configuration to its expanded configuration by application of a first force to one or more of the attachment members, and is configured to return to its unexpanded configuration upon removal of the first force; andwherein the device is configured to apply a supporting force to the tissue when the expandable member is in its expanded configuration, and wherein the expandable member comprises a first hinged portion attached to a second hinged portion. 2. The device of claim 1, wherein the tissue is urethral tissue. 3. The device of claim 1, wherein one or more of the attachment members is configured to translate the first force into a second force. 4. The device of claim 3, wherein the second force is substantially normal to the first force. 5. The device of claim 3, wherein the second force is a tensile force. 6. The device of claim 1, wherein the expandable member comprises a shape memory material. 7. The device of claim 1, wherein the expandable member comprises a stimulus responsive material. 8. The device of claim 1, wherein the expandable member comprises a shape-resilient material. 9. The device of claim 1, wherein the expandable member comprises one or more flexible flaps. 10. The device of claim 1, wherein the expandable member comprises a mesh. 11. The device of claim 1, wherein the expandable member is substantially flat when in its unexpanded configuration. 12. The device of claim 1, wherein the expandable member is approximately trapezoidal in shape when in its expanded configuration. 13. The device of claim 1, wherein the expandable member comprises a cover. 14. The device of claim 13, wherein the cover comprises silicone. 15. The device of claim 1, wherein one or more of the attachment members comprises polypropylene. 16. The device of claim 1, wherein one or more of the attachment members comprises an anchoring component. 17. The device of claim 16, wherein one or more of the attachment members comprises at least one connection member for connecting the anchoring component to the expandable member. 18. The device of claim 1, wherein the first and second attachment members are approximately rectangular. 19. The device of claim 18, wherein the first and second attachment members are each between about 1 and about 4 cm in width and between about 5 and about 20 cm in length. 20. The device of claim 1, wherein one or more of the attachment members promotes tissue ingrowth. 21. A device for supporting a tissue, the device comprising: first and second flexible attachment members and at least one expandable member positioned therebetween, wherein the first and second attachment members each comprises a strip of flexible material;wherein the expandable member has an unexpanded configuration and an expanded configuration;wherein the expandable member changes from its unexpanded configuration to its expanded configuration by application of a first force to one or more of the attachment members; andwherein the device is configured to apply a supporting force to the tissue when the expandable member is in its expanded configuration, and wherein the expandable member comprises first and second hinged portions attached to a base portion, wherein the first and second hinged portions are each configured to rotate away from the base portion when the expandable member changes from its unexpanded configuration to its expanded configuration. 22. The device of claim 21, wherein the expandable member further comprises an expandable membrane attached to the first and second hinged portions. 23. The device of claim 21, wherein the expandable member further comprises a third hinged portion attached to the first hinged portion and a fourth hinged portion attached to the second hinged portion. 24. A device for supporting a tissue, the device comprising: first and second flexible attachment members and at least one expandable member positioned therebetween, wherein the first and second attachment members each comprises a strip of flexible material;wherein the expandable member has an unexpanded configuration and an expanded configuration;wherein the expandable member changes from its unexpanded configuration to its expanded configuration by application of a first force to one or more of the attachment members; andwherein the device is configured to apply a supporting force to the tissue when the expandable member is in its expanded configuration, and wherein the expandable member comprises an expandable membrane, wherein the expandable membrane is stretched when the expandable member changes from its unexpanded configuration to its expanded configuration, and is configured to return the expandable member to its unexpanded configuration when the first force is removed.
