Abstract

A device for treating valvular insufficiency that includes an expandable anchor attached to a transvalvular spacer and a delivery system for delivering the device and enabling deployment and positioning of the transvalvular spacer prior to anchoring.

Claims (12)

WHAT IS CLAIMED IS:
1. A device for treating valvular insufficiency comprising: (a) a transvalvular spacer for providing a coaptation surface to leaflets of a heart valve; and (b) an expandable anchor attached to said transvalvular spacer and being for positioning said transvalvular spacer across said heart valve when expanded in a heart chamber, said expandable anchor having a proximal connector attachable to a first element of a delivery system and a distal connector attachable to a second element of a delivery system, said first and second elements being moveable in opposite directions to expand said expandable anchor.
2. The device of claim 1, wherein said transvalvular spacer maintains a position relative to said heart valve when said first element and said second element move in opposite directions.
3. The device of claim 1, wherein a degree of movement of said first element and said second element determines an extent of expansion of said anchor.
4. The device of claim 1, further comprising a coupling element for engaging a retrieval catheter.
5. The device of claim 4, wherein said coupling element is configured for engagement via a lasso.
6. A device for treating valvular insufficiency comprising: (a) a transvalvular spacer for providing a coaptation surface to leaflets of a heart valve; and (b) an expandable anchor attached to said transvalvular spacer and being for positioning said transvalvular spacer across said heart valve when expanded in a heart chamber, said expandable anchor including a plurality of struts, wherein some of said struts include a flexible portion for enabling said transvalvular spacer to tilt with respect to said expandable anchor when expanded.
7. The device of claim 6, wherein said flexible portion is an undulating portion.
8. A method of treating valvular insufficiency comprising: (a) deploying within a heart valve a transvalvular spacer having a balloon for providing a coaptation surface to leaflets of said heart valve; and (b) inflating said balloon within said heart valve to a volume that meets a coaptation goal; (b) expanding an expandable anchor attached to said transvalvular spacer within a heart chamber to thereby anchor said transvalvular spacer across said heart valve.
9. The method of claim 8, wherein said transvalvular spacer maintains a position relative to said heart valve when said expandable anchor is expanded.
10. The method of claim 8, further comprising deflating and optionally reinflating said balloon following (b).
11. The method of claim 8, wherein said expandable anchor further comprises a coupling element for engaging a retrieval catheter.
12. The method of claim 11, further comprising deflating said transvalvular spacer following (b) and using said retrieval catheter to engage said coupling element.
