1. An expandable stent for implantation in a right ventricular outflow tract, the expandable stent comprising:
a frame including:
a waist portion that expands to a deployed size having a first diameter, the waist portion being defined by at least one row of generally diamond-shaped cells formed by the frame;
a first sealing portion extending from the waist portion and expanding radially outward of the waist portion, wherein the first sealing portion is sized to seal against a first portion of an inner surface of a right ventricular outflow tract at a deployed position over a range of sizes of expansion having a second diameter larger than the first diameter; and
a second sealing portion extending from the waist portion in a direction opposite the first sealing portion and expanding radially outward of the waist portion, wherein the second sealing portion is sized to seal against a second portion of the inner surface of the right ventricular outflow tract at the deployed position over a range of sizes of expansion having a third diameter larger than the first diameter;
a fabric cover secured to the frame at least at the first and second sealing portions; and
a band secured to the waist portion of the frame, the band being separate from and overlapping with the fabric cover and having a width that covers the at least one row of generally diamond-shaped cells without extending beyond the waist portion, the band restricting expansion of the waist portion substantially beyond the first diameter, such that the waist portion is configured to be spaced apart from the inner surface of the right ventricular outflow tract at the deployed position
wherein the fabric cover is secured to an exterior of the frame to define an exterior surface of the expandable stent, and the band is secured to an interior of the frame to define an interior surface of the expandable stent.
