Abstract: A prosthetic heart valve delivery system having one or more features which facilitate access to a target annulus and improve maneuverability. The system may have a flexible access sheath having an inner lumen and a proximal handle attached to an elongated flexible catheter extending distally therefrom and having an outer diameter sized to fit through the access sheath. An expandable prosthetic heart valve is crimped and positioned in an inner lumen and near the distal end of the delivery catheter. A distal tapered nose cone attaches to the delivery catheter and facilitates passage through the patient's vasculature. An inner tube extends from the proximal handle through the delivery catheter inner lumen, through the prosthetic heart valve, and attaches to the nose cone. Finally, the system has a guidewire that extends through the proximal handle along the delivery catheter and projects distally from the nose cone. The system is especially useful for transfemoral atrioventricular valve replacements.
