Abstract

A system for implanting a heart valve includes a radially self-expandable tubular body having an inflow end and an outflow end and a projection extending from a side surface of the tubular body toward the inflow end. The system further includes a valve disposed within and attached to the tubular body, and may include fabric that forms a pouch between the tubular body and the projection.

Claims

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

a radially self-expandable tubular body having an inflow end and an outflow end and a projection extending from a side surface of the tubular body toward the inflow end;

a valve disposed within and attached to the tubular body; and

a fabric configured to form a pouch between the tubular body and the projection.

2. The system according to claim 1, further including an elongate outer member configured to be moved into the pouch and guide heart tissue into the pouch such that the heart tissue is between the tubular body and the elongate outer member.

3. The system according to claim 2, further including a trapping member configured to be disposed along the elongate outer member and trap the heart tissue in the pouch.

4. The system according to claim 1, wherein the fabric includes a first end attached to the inflow end of the tubular body and a second end attached to the tubular body in the vicinity of the outflow end.

5. The system according to claim 1, wherein the fabric includes a first end attached to the inflow end of the tubular body and a second end attached to the projection.

6. The system according to claim 1, wherein the fabric is 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 a valve disposed within a lumen of the tubular body, a projection extending from a side surface of the tubular body toward the inflow end, a groove formed between the projection and the tubular body, and a fabric extending from the inflow end and over the projection, such that, when the tubular body is deployed, the tubular body is aligned with a native valve of the patient; and

guiding portions of native valve leaflets and/or chords into the groove and forming a pouch of the fabric in the groove with an elongate outer member disposed radially outward of the native valve.

8. The method according to claim 7, further including trapping the portions of the native valve leaflets and/or chords within the pouch with a trapping member such that a portion of the fabric is located between the trapped portions of the native valve leaflets and/or chords and the projection.

9. The method according to claim 7, wherein the fabric is polyester fabric.

10. The method according to claim 8, wherein trapping the portions of the native valve leaflets and/or chords within the pouch includes moving the trapping member within the pouch.

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

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