Abstract

A method for accessing a mitral valve that includes forming an incision and inserting a first catheter comprising a lumen. The first catheter is adapted to be directed towards a left atrium and the first catheter has a working length of approximately 15 cm to approximately 52 cm. The method further includes utilizing a trocar in the first catheter to penetrate a pericardium and utilizing the trocar to penetrate the left atrium. The method further includes accessing the mitral valve from an antegrade direction.

Claims (38)

1. A method for accessing a mitral valve, the method comprising:

forming a suprasternal incision;

inserting a retractor into the suprasternal incision, the retractor adapted to elevate a sternum;

illuminating, via at least one of the retractor and an endoscope introduced into the incision, an inside of the incision;

opening a pericardium under visualization aided by at least one of the endoscope and the retractor;

separating an aorta and a superior vena cava to facilitate access to a roof of a left atrium;

illuminating, via at least one of the retractor and the endoscope, the roof of the left atrium;

placing a suture into the left atrium under visualization aided by at least one of the retractor and the endoscope;

passing at least one of a guide wire and a catheter into the left atrium proximate the suture;

advancing at least one of the guide wire and the catheter through a mitral valve;

deploying a mitral valve repair device;

withdrawing the catheter or the guide wire;

securing the suture;

removing the retractor; and

closing the incision.

2. The method of claim 1 , wherein the incision is superior to a sternal notch.

3. The method of claim 1 , comprising inserting an endoscope into the incision, the endoscope being adapted to aid passage of instruments into the incision.

4. The method of claim 1 , comprising utilizing a steering wire to direct at least one of the catheter and the guide wire towards the left atrium.

5. The method of claim 1 , comprising utilizing a trocar to penetrate the left atrium.

6. The method of claim 1 , comprising utilizing a trocar to penetrate the pericardium.

7. The method of claim 1 , comprising:

reducing a pressure within the aorta; and

displacing the aorta.

8. The method of claim 7 , wherein the displacement of the aorta is to the left.

9. The method of claim 1 , wherein the suture is a purse string suture.

10. A method for accessing a mitral valve, the method comprising:

forming a suprasternal incision;

illuminating an inside of the incision;

opening a pericardium under visualization, aided by at least one of an endoscope and a retractor;

separating an aorta and a superior vena cava to facilitate access to a roof of a left atrium;

illuminating a roof of a left atrium;

placing a suture into the left atrium under visualization;

passing at least one of a guide wire and a catheter into the left atrium proximate the suture;

advancing at least one of the guide wire and the catheter through a mitral valve;

deploying a mitral valve repair device;

withdrawing the catheter or the guide wire;

securing the suture; and

closing the incision.
