US Patent 11439505 Apparatus and methods for delivery of prosthetic heart valves

Apparatus and methods are described herein for use in in establishing an improved AV loop with the use of a pulley/snare device at the base of a ventricle of a heart. In some methods described herein, a pulley/snare device is established to create a path with inherent concentricity to the aortic and mitral valves, allowing the valves to function normally during an interventional procedure in the heart, without impeding the motion of any leaflets. The pulley/snare device described herein minimizes the forces that are applied on the valves or associated cardiac tissue to “make the turn” from the aortic valve to the mitral valve.
