Abstract

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

Claims (30)

1. A system, comprising:

a delivery catheter;

a transvalvular intraannular implant comprising an elongate body having a longitudinal axis from a first end to a second end, wherein the transvalvular intraannular implant is configured to be transformable from a first reduced configuration to a second enlarged configuration, wherein the transvalvular intraannular implant is configured to be housed within the delivery catheter in the first reduced configuration, wherein the transvalvular intraannular implant is configured to be transformed to the second enlarged configuration within a heart of a patient and positioned such that the transvalvular intraannular implant is oriented in the heart such that the longitudinal axis of the transvalvular intraannular implant is configured to be oriented substantially transversely to a coaptive edge of a heart valve, wherein the transvalvular intraannular implant comprises a first connection section comprising a first eyelet disposed at the first end of the elongate body and a second connection section comprising a second eyelet disposed at the second end of the elongate body; and

a first tissue anchor and a second tissue anchor, wherein the first tissue anchor is configured to extend through the first eyelet of the first connection section, and wherein the second anchor is configured to extend through the second eyelet of the second connection section.

2. The system of claim 1 , wherein the first tissue anchor comprises a corkscrew.

3. The system of claim 1 , wherein the transvalvular intraannular implant is formed from a single length of wire.

4. The system of claim 1 , wherein the central section is shaped to reduce resistance to blood flow from the atrium to the ventricle.

5. The system of claim 1 , wherein the transvalvular intraannular implant does not comprise an annuloplasty ring.

6. The system of claim 1 , wherein the transvalvular intraannular implant is formed from several lengths of wire.

7. The system of claim 1 , wherein the central section is curved downward.

8. The system of claim 1 , wherein the transvalvular intraannular implant is configured to treat leaflet prolapse.

9. A system, comprising:

a delivery catheter;

a transvalvular intraannular implant comprising an elongate body having a longitudinal axis from a first end to a second end, wherein the transvalvular intraannular implant is configured to be transformable from a first reduced configuration to a second enlarged configuration, wherein the transvalvular intraannular implant is configured to be housed within the delivery catheter in the first reduced configuration, wherein the transvalvular intraannular implant is configured to be transformed to the second enlarged configuration within a heart of a patient and positioned such that the transvalvular intraannular implant is oriented in the heart such that the longitudinal axis of the transvalvular intraannular implant is configured to be oriented substantially transversely to a coaptive edge of leaflets, wherein the transvalvular intraannular implant comprises a first connection section comprising a first eyelet disposed at the first end of the elongate body and a second connection section comprising a second eyelet disposed at the second end of the elongate body, each connection section connected to a central section having an arcuate shape;

a first tissue anchor configured to be coupled to the first eyelet of the first connection section, wherein the first tissue anchor is configured to extend through the first eyelet of the first connection section, and wherein the first tissue anchor is configured to secure the first connection section to adjacent tissue of a base of a first leaflet or mitral valve annulus; and

a second tissue anchor configured to be coupled to the second eyelet of the second connection section, wherein the second tissue anchor is configured to extend through the second eyelet of the second connection section, and wherein the second tissue anchor is configured to secure the second connection section to adjacent tissue of a base of a second leaflet or mitral valve annulus.

10. The system of claim 9 , wherein the arcuate shape bows in the direction of the ventricle.

11. The system of claim 9 , wherein the arcuate shape is configured to achieve early closure of the leaflets.

12. The system of claim 9 , wherein the transvalvular intraannular implant comprises a flexible wire.

13. The system of claim 9 , wherein the transvalvular intraannular implant comprises struts.

14. The system of claim 9 , wherein bend angles of the transvalvular intraannular implant are configured to be altered.

15. The system of claim 9 , wherein the transvalvular intraannular implant comprises an axis of compression.

16. The system of claim 9 , wherein the first tissue anchor comprises a corkscrew.

17. A system, comprising:

a delivery catheter;

a transvalvular intraannular implant comprising an elongate body having a longitudinal axis from a first end to a second end, wherein the transvalvular intraannular implant is configured to be transformable from a first reduced configuration to a second enlarged configuration, wherein the transvalvular intraannular implant is configured to be housed within the delivery catheter in the first reduced configuration, wherein the transvalvular intraannular implant is configured to be transformed to the second enlarged configuration within a heart of a patient and positioned such that the longitudinal axis of the transvalvular intraannular implant is oriented relative to a first leaflet and a second leaflet, wherein the transvalvular intraannular implant comprises a first leaflet support comprising a first eyelet, the first eyelet disposed at the lateral edge of the first leaflet support, and a second leaflet support comprising a second eyelet, the second eyelet disposed at the lateral edge of the second leaflet support; and

a first anchor configured to secure the first eyelet to an atrial side of the first leaflet and a second anchor configured to secure the second eyelet to an atrial side of the second leaflet, wherein the first eyelet is configured to receive the first anchor and the second eyelet is configured to receive the second anchor.

18. The system of claim 17 , wherein the transvalvular intraannular implant is configured to provide a relatively large support footprint against the first leaflet and the second leaflet, while at the same time optimizing the area of open space to permit maximum blood flow therethrough.

19. The system of claim 17 , wherein the transvalvular intraannular implant comprises a flexible material.

20. The system of claim 17 , wherein the first anchor comprises a corkscrew.
