1. A system comprising:
- a prosthetic valve device having a self-expanding frame; and
a holder configured to retain the frame in a constricted configuration and to control expansion of the frame,wherein the holder comprises a first controllably constrictable and expandable loop, wherein the first loop is circumferentially disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame,wherein the frame comprises an inflow region,wherein the inflow region comprises an upper portion and a lower portion,wherein the first loop is disposed about at least a portion of the upper portion of the inflow region of the frame such that constriction or expansion of the first loop controls constriction or expansion of the upper portion of the inflow region of the frame,wherein the holder further comprises a second controllably constrictable and expandable loop, wherein the second loop is circumferentially disposed about at least a portion of the lower portion of the inflow region of the frame such that constriction or expansion of the second loop controls constriction or expansion of the lower portion of the inflow region of the frame, andwherein the frame comprises an outflow region and wherein the holder comprises a third controllably constrictable and expandable loop, wherein the third loop is circumferentially disposed about at least a portion of the outflow region of the frame such that constriction or expansion of the third loop controls constriction or expansion of at least a portion of the outflow region of the frame.
