Abstract

Un ensamble/montaje (200) para plegar una válvula cardíaca prostética incluye un miembro de compresión (202) y un elemento impulsor (204). El miembro de compresión tiene un primerextremo abierto (208) con un primer diámetro, un segundo extremo abierto (210) con un segundo diámetro menor que el primer diámetro, y una pared cónica (206) entre el primer extremo abierto y el segundo extremo abierto. El elemento impulsor (204) tiene una base (232) adaptada para acoplarse a un extremo de la válvula.
