1. A pre-packaged system, comprising:
a heart valve assembly, comprising:
a stent-frame comprising an anchoring section and an outflow section, the anchoring section having a distal annulus section and a support section that is positioned between the distal annulus section and the outflow section,
wherein the distal annulus section is defined by a single distal row of cells that has a concave inflection,
wherein the outflow section is defined by a single proximal row of cells, and
a leaflet assembly stitched to the anchoring section, the leaflet assembly having leaflets that have been treated with dry tissue technology; and
a delivery catheter having a balloon on which the heart valve assembly is pre-crimped, the balloon comprising:
a proximal section and a distal section; and
a central valve contact portion positioned between the proximal and distal sections, the contact portion having an outflow portion, a neck portion, and a central portion between the outflow portion and the neck portion, wherein the neck portion has an inflection zone that corresponds in size and shape with the concave inflection of the distal annulus section; and
wherein the heart valve assembly is pre-crimped on the balloon such that the outflow portion of the balloon receives the outflow section of the stent-frame, the central portion of the contact portion of the balloon receives the support section of the stent-frame, and the neck portion receives the annulus section of the stent-frame.
