摘要:
Transcatheter guidewire delivery systems, catheter assemblies and associated methods for percutaneous guidewire delivery across heart valves are disclosed herein. A catheter assembly configured in accordance herewith includes an elongated tubular component and an alignment assembly at a distal portion of the tubular component and which is adapted to be located at a target location adjacent a heart valve of a patient. In one embodiment, the alignment assembly deploys to a shape set loop configuration with a side port in an open configuration positioned to allow advancement of a guidewire to exit the catheter in an aligned path with a leaflet coaptation region of the heart valve. In another embodiment, the alignment assembly has a plurality of spaced apart side ports that a guidewire may advance therethrough and toward the heart valve. In some embodiments, a wire guide is used to align the guidewire with a selected side port.
