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.
Claims27
A method for accessing a mitral valve, the method comprising:
- forming a percutaneous suprasternal incision;
- entering a pericardium, via the suprasternal incision, utilizing at least one of a catheter and a guide wire;
- passing the at least one of the catheter and the guide wire between an aorta and a superior vena cava;
- separating the aorta and the superior vena cava in order to create a space between the aorta and the superior vena cava to facilitate access to a roof of a left atrium;
- placing a closure device into the left atrium;
- passing the at least one of the catheter and the guide wire into the left atrium proximate the closure device;
- advancing the at least one of the guide wire and the catheter through a mitral valve;
- deploying at least one of a mitral valve repair device and a mitral valve prosthesis;
- withdrawing the at least one of the catheter and the guide wire;
- and
- securing the left atrium using the closure device.
A method for accessing a mitral valve, the method comprising:
- incising a skin of a neck region above a sternal notch for percutaneous entry;
- advancing a catheter inferiorly under the sternal notch into a mediastinum;
- penetrating a pericardium with the catheter;
- advancing the catheter between an aorta, a superior vena cava, and a right pulmonary artery;
- separating, using the catheter, the aorta and the superior vena cava to create a space between the aorta and the superior vena cava;
- introducing devices along the catheter to perform interventions on cardiac structure;
- and
- directing closure devices along the catheter.
