PROSTHETIC HEART VALVE HAVING NON-LINEAR STRUTS

摘要

An implantable prosthetic device can include a frame that is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The frame can include a plurality of struts, each strut comprising a first portion and a second portion separated by a deflection point. Each strut can be curved helically with respect to a first, longitudinal axis of the frame. The first portion of each strut can be curved in a first direction with respect to a first line parallel to a second axis that is perpendicular to the first, longitudinal axis of the frame, and the second portion of each strut can be curved in a second direction with respect to a second line parallel to the second axis.
