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 deployable surgical platform, comprising:

expanding means for anchoring the platform at the site of a procedure; and

anchoring means for anchoring one or more catheters to the expanding means.

2. A deployable surgical platform according to claim 1, wherein said expanding means includes an inflatable balloon.

3. A deployable surgical platform according to claim 1, wherein said expanding means is a solid expandable annular means expandable by means of unrolling a rolled-up solid expandable means.

4. A deployable surgical platform according to claim 1, wherein said expanding means includes multiple deformable projections that project from the distal end of a catheter or other tubular device.

5. A deployable surgical platform according to claim 1, wherein said expanding means incorporates a one-way valve.

6. A deployable surgical platform according to claim 1, wherein said expanding means incorporates a mesh or sieve.

7. A system for the removal and delivery of a medical device, the system comprising:

a deployable surgical platform anchorable distal to the medical device, the surgical platform including;

(a) hollow expanding means anchorable at the site of the medical device; and

(b) anchoring means for anchoring at least one catheter or surgical tool to the hollow expanding means.

8. A system for the removal and delivery of a medical device according to claim 7, wherein said anchoring means for catheter or surgical tools includes a twist connection.

9. A system for the removal and delivery of a medical device according to claim 7, wherein said anchoring means includes a snap connection.

10. A system for the removal and delivery of a medical device according to claim 7, wherein said system further comprises tracking means to locate the position of said medical device in 3-D space.

11. A system for the removal and delivery of a medical device according to claim 10, wherein said tracking means uses sensors that are mounted to said medical device to locate said medical device in 3-D space.

12. A system for the removal and delivery of a medical device according to claim 7, wherein said at least one catheter has a longitudinally-extending slot, said slot dimensioned to allow a central sliding means to partially project therethrough and slide along said slot.

13. A system for the removal and delivery of a medical device according to claim 12, wherein said central sliding means includes gripping means for reversibly connecting said medical device to said central sliding means.

14. A system for the removal and delivery of a medical device according to claim 12, wherein said central sliding means is moved through a lumen of said at least one catheter by internal pull wire means.
