Abstract

A system for implanting a heart valve includes a radially self-expandable tubular body having an inflow end and an outflow end, a decorrelation portion, and a preformed groove disposed at an outer surface of the tubular body between the decorrelation portion and the outflow end. The preformed groove extends at least partially around the tubular body, and has a circumferential opening facing radially outward of the tubular body. A valve is disposed within and attached to the tubular body. The decorrelation portion is configured to dissociate axial and radial movements between the inflow end of the tubular body and the outflow end of the tubular body.

Claims

1. A system for implanting a heart valve, comprising:

a radially self-expandable tubular body having an inflow end and an outflow end, a decorrelation portion, and a preformed groove disposed at an outer surface of the tubular body between the decorrelation portion and the outflow end, the preformed groove extending at least partially around the tubular body and having a circumferential opening facing radially outward of the tubular body; and

a valve disposed within and attached to the tubular body, wherein

the decorrelation portion is configured to dissociate axial and radial movements between the inflow end of the tubular body and the outflow end of the tubular body.

2. The system according to claim 1, wherein the decorrelation portion is disposed between the valve and the inflow end.

3. The system according to claim 1, further including a trapping member configured to be moved into the preformed groove to form at least a partial loop around the tubular body.

4. The system according to claim 1, wherein the decorrelation portion is disposed adjacent to and outside the preformed groove.

5. The system according to claim 1, wherein the decorrelation portion includes a flexible “

S”

shaped portion.

6. The system according to claim 1, wherein the decorrelation portion is comprised of polyester fabric.

7. A method for implanting a replacement valve in a patient'"'"'s heart, comprising:

deploying from a delivery catheter a radially self-expandable tubular body having an inflow end and an outflow end, a valve disposed within a lumen of the tubular body, a decorrelation portion, a preformed groove disposed at an outer surface of the tubular body between the decorrelation portion and the outflow end, the groove extending at least partially around the tubular body and having a circumferential opening facing radially outward of the tubular body, such that, when the tubular body is deployed, the tubular body is aligned with a native valve and the decorrelation portion dissociates axial and radial movements between the inflow end of the tubular body and the outflow end of the tubular body.

8. The method according to claim 7, further including advancing an elongate outer member into the preformed groove and forming a loop around the preformed groove and portions of native valve leaflets and/or chords with the elongate outer member.

9. The method according to claim 8, further including advancing a trapping member into the preformed groove and forming at least a partial loop within the preformed groove with the trapping member, thereby trapping the portions of native valve leaflets and/or chords in the preformed groove.

10. The method according claim 9, further including removing the elongate outer member from the patient.

11. The method according to claim 7, wherein the native valve is a mitral valve or a tricuspid valve.
