Abstract

A structure and method for deploying an eyelet in a membrane, where the eyelet includes: a waist section; a first anchor section coupled to and flared from the waist section; and a second anchor section coupled to and flared from the waist section. The eyelet is deployed such that the waist section is located within a membrane opening of the membrane thus keeping the membrane opening open. Further, the membrane is sandwiched between the first and second anchor sections thus anchoring the eyelet to the membrane.

Claims

1. An eyelet for deployment in a membrane comprising:

a waist section for keeping an opening of said membrane open;

a first anchor section coupled to said waist section; and

a second anchor section coupled to said waist section.

2. The eyelet of claim 1 wherein said eyelet is cylindrical.

3. The eyelet of claim 2, wherein said waist section, said first anchor section and said second anchor section have a same diameter.

4. The eyelet of claim 1 wherein said waist section, said first anchor section, and said second anchor section comprises expandable elements.

5. The eyelet of claim 4 wherein said expandable elements comprise serpentine rings.

6. The eyelet of claim 1 wherein said waist section comprises a plurality of expandable elements.

7. The eyelet of claim 6 wherein said expandable elements comprise serpentine rings.

8. The eyelet of claim 1 wherein said first anchor section comprises an expandable element.

9. The eyelet of claim 8 wherein said expandable element comprises a serpentine ring.

10. The eyelet of claim 1 wherein said first anchor section comprises a plurality of expandable elements.

11. The eyelet of claim 10 wherein said expandable elements comprise serpentine rings.

12. The eyelet of claim 10 wherein said expandable elements comprise a stabilizing ring.

13. The eyelet of claim 1 wherein said waist section is coupled to said first anchor section with a plurality of bridges comprising a first bridge.

14. The eyelet of claim 13 wherein said waist section comprises a material and wherein said first anchor section comprises said material, said material of said waist section being coupled to said material of said first anchor section to form said first bridge.

15. The eyelet of claim 13 wherein said waist section comprises a first metallic core and a first polymer and wherein said first anchor section comprises a second metallic core and a second polymer, said first polymer of said waist section being coupled to said second polymer of said first anchor section to form said first bridge.

16. The eyelet of claim 13 wherein said waist section comprises a first metallic core and a first polymer and wherein said first anchor section comprises a second metallic core and a second polymer, said first polymer and said first metallic core of said waist section being coupled to said second polymer and said second metallic core of said first anchor section, respectively, to form said first bridge.

17. The eyelet of claim 1 wherein said eyelet comprises a metallic core and a polymer on a surface of said metallic core.

18. The eyelet of claim 17 wherein said eyelet comprises a laminate structure.

19. The eyelet of claim 17 wherein said surface is selected from the group consisting of an inner cylindrical surface and an outer cylindrical surface of said eyelet.

20. A deployed eyelet comprising:

a waist section for maintaining the patency of an opening in a membrane;

a first anchor section coupled to and flared from said waist section; and

a second anchor section coupled to and flared from said waist section.

21. The deployed eyelet of claim 20 wherein said waist section has a first diameter.

22. The deployed eyelet of claim 21 wherein a first edge of said first anchor section is coupled to a first edge of said waist section, said first anchor section having said first diameter at said first edge of said first anchor section.

23. The deployed eyelet of claim 22 wherein said first anchor section has a second edge having a second diameter greater than said first diameter.

24. The deployed eyelet of claim 23 wherein said first anchor section has an increasing diameter between said first edge of said first anchor section and said second edge of said first anchor section.

25. The deployed eyelet of claim 20 wherein an angle between said first anchor section and a longitudinal axis of said eyelet is less than 90°

.

26. The deployed eyelet of claim 25 wherein said first anchor section defines a conical surface.

27. The deployed eyelet of claim 20 wherein an angle between said first anchor section and a longitudinal axis of said eyelet is 90°

.

28. The deployed eyelet of claim 27 wherein said first anchor section defines a plane perpendicular to said longitudinal axis.

29. The deployed eyelet of claim 20 wherein said first anchor section comprises a first serpentine ring and a stabilizing ring, said stabilizing ring connecting peaks of said first serpentine ring.

30. A structure comprising:

a membrane comprising an opening surface defining an opening between a first region and second region; and

a membrane eyelet comprising;

a waist section in contact with said opening surface;

a first anchor section coupled to and flared from said waist section; and

a second anchor section coupled to and flared from said waist section,

wherein said membrane is sandwiched between said first anchor section and said second anchor section.

31. The structure of claim 30 wherein said membrane is a single integral membrane.

32. The structure of claim 30 wherein said membrane is the floor of the third ventricle.

33. The structure of claim 30 wherein said membrane comprises two or more membranes.

34. The structure of claim 30 wherein said first anchor section, said second anchor section or said first and second anchor sections are spaced apart from said membrane.

35. An eyelet comprising:

a first anchor section;

a second anchor section; and

bridges coupling said first anchor section to said second anchor section, said bridges defining a waist section of said eyelet, wherein said eyelet is cylindrical prior to deployment and further wherein said first anchor section and said second anchor section flare from said waist section after deployment of said eyelet, said waist section for maintaining the patency of an opening in a membrane.

36. A method comprising:

inserting a membrane eyelet into an opening of a membrane such that a waist section of said membrane eyelet is located in said opening; and

radially expanding said membrane eyelet such that said membrane is sandwiched between a first anchor section and a second anchor section of said membrane eyelet.

37. The method of claim 36 wherein said radially expanding comprises flaring said first anchor section and said second anchor section from said waist section.

38. The method of claim 36 wherein said membrane is the floor of the third ventricle.

39. A method comprising:
