Abstract: A medical device delivers an implant by securing, folding, and releasing it through coordinated component movements. The device includes a first component with opposing jaws or a slot for releasably securing the implant in a flat configuration.

The second component both pivots and translates relative to the first component. Movement control utilizes pins with discorectangle profiles extending from the first component that engage compound apertures in the second component, where each aperture has a round portion permitting rotation and a rectilinear portion preventing rotation. Detents and recesses facilitate smooth transitions between portions.
