Patent Images
1. A method of repairing a heart valve in a beating heart of a patient, comprising:
- inserting an external guide catheter through a vein of a patient and into a right atrium of a heart of a patient;
advancing the external guide catheter into a right ventricle of the patient'"'"'s heart;
inserting an internal guide catheter into the external guide catheter and advancing the internal guide catheter into the right ventricle;
puncturing a septum in the patient'"'"'s heart to create an opening between the right ventricle and a left ventricle;
advancing the internal guide catheter through the opening in the septum and into the left ventricle;
inserting a deployment catheter through the internal guide catheter and advancing the deployment catheter adjacent a heart valve in the left ventricle; and
deploying a repair device onto the heart valve with the deployment catheter.

Abstract
A method of repairing a heart valve provides intravascular access for repair of a heart valve through a ventricular trans-septal approach. An external guide catheter can be inserted through a vein of a patient into the right ventricle via the right atrium. An internal guide catheter can be inserted through the external guide and can provide access to the septum for a puncture tool to create an opening through the septum to the left ventricle. The internal guide can then be advanced into the left ventricle and used to guide a deployment catheter that deploys a repair device onto the heart valve.

10. A method comprising:
-
providing a heart valve repair system, the system including an external guide catheter, an internal guide catheter adapted to be slidably inserted through the external guide catheter, a septal puncture tool and a deployment catheter; and providing instructions for deploying a repair device onto a heart valve of a beating heart of a patient with the heart valve repair system, the instructions comprising; inserting the external guide catheter through a vein of the patient and into a right atrium of a heart of the patient; advancing the external guide catheter into a right ventricle of the patient'"'"'s heart; inserting the internal guide catheter into the external guide catheter and advancing the internal guide catheter into the right ventricle; inserting the septal puncture tool through the internal guide catheter and puncturing a septum of the patient with the septal puncture tool to create an opening through the septum between the right ventricle and a left ventricle; advancing the internal guide catheter through the opening in the system and into the left ventricle; inserting the deployment catheter through the internal guide catheter and advancing the deployment catheter adjacent the heart valve; and deploying a repair device onto the heart valve with the deployment catheter. - View Dependent Claims (11, 12, 13, 14, 15)
