Abstract

An occluder device for occluding a gap between a medical device and adjacent body tissue includes a conformable body having a hollow interior, a leading end and a trailing end; and a port disposed at the trailing end of the body and in fluid communication with the interior of the body.

Claims

1. An occluder device for occluding a gap between a medical device and adjacent body tissue, the occluder device comprising:

a conformable body having a hollow interior, a leading end and a trailing end; and

a port disposed at the trailing end of the body and in fluid communication with the interior of the body.

2. The occluder device of claim 1, wherein the body is an elongated balloon-like structure.

3. The occluder device of claim 1, wherein the body is a triangular prism.

4. The occluder device of claim 1, wherein the body is accordion-like and includes a plurality of bellows that expand and contract to change the shape of the body.

5. The occluder device of claim 1, wherein the medical device is a prosthetic heart valve having a collapsible and expandable stent forming cells, and a valve assembly disposed in the stent for controlling the flow of blood through the stent and wherein the body is crescent-shaped and has a curvature that complements a curvature of the heart valve.

6. The occluder device of claim 1, further comprising a source of in fluid communication with the port.

7. The occluder device of claim 1, further comprising a source of polymeric filler in fluid communication with the port.

8. An occluder device for occluding a gap between a medical device and adjacent body tissue, the occluder device comprising:

a conformable body having a leading end and a trailing end; and

a securing feature coupleable to the conformable body and at least one of the medical device and the adjacent body tissue.

9. The occluder device of claim 8, wherein the securing feature comprises an anchor and a cord for coupling the anchor to the body, the anchor being configured to couple to at least one of the medical device and the adjacent body tissue.

10. The occluder device of claim 9, wherein the anchor has at least one sharp end for piercing the adjacent body tissue.

11. The occluder device of claim 8, wherein the securing feature includes a plurality of velcro-like hooks disposed on the body and the medical device includes a cuff having perforations coupleable to the plurality of hooks.

12. The occluder device of claim 8, wherein the securing feature includes a clasp coupled to the leading end of the body, the clasp being configured to cup over the adjacent body tissue.

13. The occluder device of claim 12, wherein the clasp has a sharp end for piercing the adjacent body tissue.

14. The occluder device of claim 8, wherein the securing feature includes a tether having a first end secured to the leading end of the body and a second end secured to an anchoring ring, the anchoring ring being spaced away from the medical device.

15. The occluder device of claim 8, wherein the securing feature includes a plurality of barbs disposed on the body.

16. The occluder device of claim 8, wherein the securing feature includes a first magnetic element on the occluder device and a second magnetic element on the medical device, the first magnetic element and the second magnetic element being configured to attract one another to secure the occluder device to the medical device.

17. The occluder device of claim 8, wherein the securing feature includes a staple for securing the body to the adjacent body tissue.

18. The occluder device of claim 8, wherein the securing feature includes a locking feature including a bit protruding from the body of the occluder device and a receiver coupled to the medical device and having an aperture sized to receive the bit.

19. The occluder device of claim 18, wherein the receiver includes a narrow slot with an enlarged opening therein, the bit being sized to pass through the enlarged opening but not the narrow slot.
