Abstract

A cardiovascular valve system including a permanent base unit that is affixed to the patient using conventional sutures or staples, and a collapsible valve having a collapsible frame that mates with the permanent base unit, and supports valve leaflets. An installed collapsible frame may be re-collapsed and disengaged from the permanent housing. A new collapsible valve is then installed, to resume the function of the prosthesis.

Claims

1. A delivery system for shuttling a component to or from an operative site, the delivery system comprising:

one or more manipulation devices, at least one manipulation device having a first member and a slide means moveable relative to the first member, said slide means including gripping means to grip the component; and

a platform for anchoring the one or more manipulation devices, the platform including;

an annular wall defining a lumen, said annular wall expandable to anchor the platform at the operative site, and

one or more slots formed in the annular wall of the platform to respectively receive the one or more manipulation devices, for anchoring distal ends of the one or more manipulation devices to the platform.

2. A delivery system according to claim 1, wherein said annular wall is comprised of an inflatable balloon for expanding of a diameter of the annular wall.

3. A delivery system according to claim 1, wherein said platform includes a rotatable shaft for expanding a diameter of the annular wall.

4. A delivery system according to claim 1, wherein said gripping means comprises a spring-loaded clamp.

5. A delivery system according to claim 1, wherein said platform includes a one-way valve located within said lumen defined by the annular wall.

6. A delivery system according to claim 1, wherein said platform includes a mesh or sieve that enshrouds said lumen defined by the annular wall.

7. A delivery system according to claim 1, wherein said system further comprises tracking means to locate the position of said component in 3-D space.

8. A delivery system according to claim 7, wherein said tracking means includes sensors mounted to said component to locate said component in 3-D space.

9. A delivery system according to claim 1, wherein said first member is a sheath that defines an inner lumen, wherein said slide means moves within the inner lumen.

10. A delivery system according to claim 9, wherein said sheath includes a longitudinally-extending slot, said slot dimensioned to allow said gripping means to at least partially project therethrough.

11. A delivery system according to claim 9, wherein said slide means includes an inner catheter.

12. A delivery system according to claim 1, wherein said system includes pull wire means for moving said slide means relative to the first member.

13. A delivery system according to claim 1, wherein said slide means includes a surgical tool.

14. A delivery system according to claim 1, wherein said platform includes an occluding balloon located within said lumen defined by the annular wall.

15. A delivery system according to claim 1, wherein said one or more manipulation devices include a catheter.

16. A delivery system according to claim 1, wherein said at least one manipulation device is a catheter.
