Abstract

The devices and methods described can be used to create and maintain a working space within the lumen of an organ or between or among organs or tissue structures during medical procedures in order to elicit a diagnosis, biopsy, surgery, or therapy.

Claims

1. An endo frame comprising a flexible structure having a collapsed configuration and an expanded configuration, the expanded configuration being larger in diameter than the collapsed configuration.

2. The endo frame of claim 1, wherein the collapsed configuration has a diameter sufficient for insertion in a lumen through a trocar and the expanded configuration has a rigidity sufficient to push against the wall of the lumen to create a working space.

3. The endo frame of claim 1, wherein the expanded configuration has a cylindrical shape.

4. The endo frame of claim 3, wherein the flexible structure comprises circular rings at the ends of the cylindrical shape.

5. The endo frame of claim 4, wherein the flexible structure comprises longitudinal struts connecting the circular rings.

6. The endo frame of claim 5, wherein the longitudinal struts include spring steel.

7. The endo frame of claim 4, wherein the flexible structure comprises an open woven mesh connecting the circular rings.

8. The endo frame of claim 4, wherein the circular rings include woven wire springs with a hollow circumferential space.

9. The endo frame of claim 8, wherein the circular rings include a super elastic metal wire inside the hollow circumferential space.

10. The endo frame of claim 8, wherein the circular rings include a shape memory metal wire inside the hollow circumferential space.

11. The endo frame of claim 1, wherein the flexible structure has open ends and open sides.

12. The endo frame of claim 1, wherein the collapsed configuration is configured to be pushed through a sheath tube.

21. A method of creating interluminal space of a patient comprising:

introducing the endo frame of claim 1 into the lumen of the patient through a trocar; and

expanding the endo frame inside the lumen.

22. The method of claim 21, wherein a single person introduces and expands the endo frame.

23. The method of claim 22, wherein the person introduces and expands the endo frame with one hand.

13. A scroll endo frame comprising a sheet material connected to a longitudinal strut, wherein the longitudinal strut includes a roller system configured to roll or unroll the sheet material.

14. The scroll endo frame of claim 13, wherein the rolled configuration has a diameter sufficient for insertion in a lumen through a trocar and the unrolled configuration has a rigidity sufficient to push against the wall of the lumen to create a working space.

15. The scroll endo frame of claim 13, further comprising pusher tube with a wire configured to cause the roller system to roll or unroll the sheet material.

16. The scroll endo frame of claim 13, wherein the sheet material is a coiled wire lattice sheet.

17. The scroll endo frame of claim 13, wherein the sheet material includes spring steel.

18. The scroll endo frame of claim 13, wherein the sheet material includes Nitinol.

19. The endo frame of claim 13, wherein the sheet material is held in its coiled position inside a sheath.

20. The endo frame of claim 13, wherein the longitudinal strut connects to or disconnects from the pusher tube through magnetic coupling.
