Prosthetic Heart Valve Dilatation Apparatus

An inflation apparatus for dilating a prosthetic heart valve comprising an annular frame extending along a longitudinal axis between an inflow end and an outflow end, the frame comprising a plurality of struts and configured to be adjustable between a radially-collapsed position and a radially-expanded position, the frame comprising a first section at the inflow end, a second section at the outflow end, a waist section positioned between the first section and the second section, and a valve prosthesis comprising at least one leaflet attached to the plurality of struts;

• the inflation apparatus configured to be positing within the frame and comprising:
• a first balloon configured to be positioned in the first section, the first balloon configured to be pressurized from a deflated state to an inflated state, the first balloon comprising a first balloon diameter in the inflated state such that the first balloon is configured to be in contact with an interior surface of the first section, the first balloon extending between a first balloon end and a second balloon end, the first balloon end configured to be spaced a first distance from the at least one leaflet and the second balloon end configured to be spaced a second distance from the at least one leaflet;
• a catheter configured to extend through the interior of the frame and comprising a first hollow chamber in fluid communication with the first balloon;
• and
• a fluid source in fluid communication with the catheter, the fluid source configured to deliver a fluid through the first hollow chamber to the first balloon.
