1. A stented prosthetic heart valve comprising:
- a stent frame including a plurality of cells formed by segments adjoined at a plurality of nodes;
the stent frame further including a first frame end and a second frame end;
a plurality of valve leaflets positioned within the stent frame; and
a wrap connected to the stent frame with at least one elongated member;
each elongated member having two ends;
wherein at least one end of the elongated member is secured to the stent frame;
wherein the wrap has a delivery arrangement and a deployed arrangement that is actuated by expansion of the stent frame;
wherein each elongated member extends from the wrap in a first direction, wraps around one respective node and then extends in a second direction that is different than the first direction.

Abstract
Systems and methods of delivering and deploying a stented prosthetic heart valve having a wrap that is automatically deployed to prevent or mitigate paravalvular leakage. In various embodiments, during transcatheter delivery of the stented prosthetic heart valve, the wrap is extends beyond a stent frame of the stented prosthetic heart valve so that the profile of the stented prosthetic heart valve is not increased during delivery. The disclosed embodiments are arranged and configured so that upon expansion of a stent frame of the stented prosthetic heart valve, a plurality of elongated members automatically pull the wrap distally into a deployed arrangement.
