Abstract

A method for implanting a heart valve includes advancing an elongate outer member from a first delivery catheter to form a loop around native valve leaflets and/or chords of a native valve without substantially occluding the native valve. The method further includes partially deploying from a second delivery catheter a radially self-expandable tubular body having a valve disposed within a lumen of the tubular body, and a preformed groove disposed at an outer surface of the tubular body. The preformed groove extends at least partially around the tubular body, and has a circumferential opening facing radially outward of the tubular body. When the tubular body is partially deployed, the native valve is substantially occluded. Additionally, the method includes moving the loop into the preformed groove after partially deploying the tubular body. The native valve is no longer substantially occluded after fully deploying the tubular body from the second delivery catheter.

Claims

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

advancing an elongate outer member from a first delivery catheter to form a loop around native valve leaflets and/or chords of a native valve with the elongate outer member without substantially occluding the native valve;

partially deploying from a second 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, and a preformed groove disposed at an outer surface of the tubular body between the inflow end 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, such that, when the tubular body is partially deployed, the native valve is substantially occluded;

moving the loop into the preformed groove after partially deploying the tubular body from the second delivery catheter; and

fully deploying the tubular body from the second delivery catheter after moving the loop into the preformed groove so that the native valve is no longer substantially occluded.

2. The method according to claim 1, wherein moving the loop into the preformed groove includes trapping the native valve leaflets and/or chords within the preformed groove.

3. The method according to claim 1, further including advancing a trapping member along the elongate outer member and around the fully deployed tubular body without substantially occluding the native valve.

4. The method according to claim 1, further including advancing a trapping member along the elongate outer member and around the partially deployed tubular body without substantially occluding the native valve.

5. The method according to claim 3, wherein advancing the trapping member along the elongate outer member includes advancing the trapping member between at least two projections of the tubular body.

6. The method according to claim 4, wherein advancing the trapping member along the elongate outer member includes advancing the trapping member between at least two projections of the tubular body.

7. The method according to claim 1, wherein the native valve is a mitral valve or a tricuspid valve.

8. The method according to claim 7, further comprising advancing the second delivery catheter through an atrial wall.

9. The method according to claim 7, further comprising advancing the first delivery catheter through a femoral artery.

10. The method according to claim 7, further comprising removing the elongate outer member from the patient.
