Abstract: 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.

Abstract: An implantable prosthetic valve can include a frame movable between a radially compressed and a radially expanded configuration. The frame can include a first strut having a first locking feature disposed on a radially facing inner surface of the strut and a second strut having a second locking feature disposed on a radially facing outer surface of the strut. The first and second locking features can engage each other so as to allow pivoting of the first and second struts relative to one another in a first direction upon radial expansion of the frame and resist pivoting of the first and second struts relative to one another in a second direction to resist radial compression of the frame.

Abstract: A device which serves the dual purpose of allowing locking or the bicycle to prevent theft and to allow inflation of a bicycle tire tube. The device includes a U-shaped shackle having its open end closed by a cross member which defines an air pump for inflating a bicycle tire.
