Abstract

Claims (27)

1 . A docking device for a prosthetic heart valve, the docking device comprising:

an inflow end;

an outflow end;

a support structure disposed between the inflow end and the outflow end, the support structure comprising:

an inflow section extending from the inflow end of the docking device toward the outflow end of the docking device and configured to be positioned on an inflow side of a native heart valve; and

an outflow section extending between the outflow end of the docking device and the inflow section of the support structure and configured to be positioned on an outflow side of the native heart valve, wherein the outflow section comprises a first portion, a second portion, and a third portion, wherein the first portion extends distally from the inflow section to the third portion, wherein the third portion extends distally from the first portion to the second portion, and wherein the second portion extends distally from the third portion to the outflow end of the docking device; and

an expandable sleeve that covers at least a portion of the support structure and comprises a first end that is fixedly coupled to the support structure and a second end that is configured to move axially relative to the support structure,

wherein the expandable sleeve is movable from a compressed position to an expanded position when a crimping pressure is released and the second end of the expandable sleeve moves axially relative to the support structure, and

wherein in the expanded position, the expandable sleeve extends at least 100 degrees over the first portion of the outflow section of the support structure.

2 . The docking device of claim 1 , wherein the expandable sleeve extends over the first portion of the outflow section at least 100 degrees from the inflow section of the support structure towards the outflow end of the docking device and is configured to extend to and directly physically contact the third portion of the outflow section of the support structure when the expandable sleeve is in the expanded position.

3 . The docking device of claim 1 , wherein the expandable sleeve extends over the inflow section of the support structure at least 100 degrees from the outflow section of the support structure towards the inflow end of the docking device.

4 . The docking device of claim 1 , wherein the expandable sleeve comprises a single continuous sleeve that extends between the inflow section and the outflow section of the support structure.

5 . The docking device of claim 4 , wherein the expandable sleeve comprises a first portion that extends over the inflow section of the support structure, a second portion that extends over the outflow section of the support structure, and an intermediate portion that is disposed between the first portion and the second portion.

6 . The docking device of claim 5 , wherein the expandable sleeve is tapered in the intermediate portion, such that the intermediate portion is narrower than the first portion and the second portion of the expandable sleeve.

7 . The docking device of claim 5 , wherein the intermediate portion extends at least 45 degrees from the inflow section of the support structure over the first portion of the outflow section of the support structure towards the outflow end of the support structure.

8 . The docking device of claim 1 , wherein at least one of the first and second ends of the expandable sleeve is tapered.

9 . The docking device of claim 1 , wherein the expandable sleeve comprises two discrete sleeves that are separated from one another by a gap.

10 . The docking device of claim 9 , wherein the expandable sleeve comprises a first sleeve that extends along the inflow section of the support structure and a second sleeve that extends along the outflow section of the support structure.

11 . The docking device of claim 10 , wherein the gap is at least 45 degrees.

12 . The docking device of claim 10 , wherein the first sleeve comprises a proximal end and a distal end, wherein the first sleeve extends towards the inflow end of the docking device from the distal end to the proximal end, and wherein the first sleeve is coupled to the support structure at the distal end.

13 . The docking device of claim 12 , wherein the first sleeve is tapered at the distal end.

14 . The docking device of claim 10 , wherein the second sleeve comprises a proximal end and a distal end, wherein the second sleeve extends towards the inflow end of the docking device from the distal end to the proximal end, and wherein the second sleeve is coupled to the support structure at the distal end.

15 . The docking device of claim 14 , wherein the second sleeve is tapered at one or more of the distal end and the proximal end.

16 . The docking device of claim 1 , wherein the first portion of the support structure has a different geometry than the third portion of the support structure.

17 . The docking device of claim 16 , wherein the first portion has a different shape than the third portion of the support structure when viewed in a plane perpendicular to a longitudinal axis of the docking device.

18 . The docking device of claim 16 , wherein the first portion has a different size than the third portion of the support structure when viewed in a plane perpendicular to a/the longitudinal axis of the docking device.

19 . The docking device of claim 18 , wherein the first portion is larger than the third portion of the support structure when viewed in the plane perpendicular to the longitudinal axis of the docking device.
