Abstract
Aspects of the disclosure include systems including a delivery device having a handle assembly, a shaft assembly having a distal portion, and a helical elongated member positioned at least partially over the shaft assembly and interconnected to the handle assembly. The system also includes a prosthesis positioned over the distal portion. The prosthesis has a stent frame having an inner surface and an outer surface, a valve structure positioned within the stent frame, and a track formed by one or more guides positioned on and extending from one of the inner or outer surfaces of the stent frame. The helical elongated member is configured to be moved in and out of the track to selectively compress or allow the prosthesis to expand. Methods of loading and delivering the prosthesis using systems of the disclosure are also disclosed.
