Abstract

Embodiments of the present disclosure are directed to stents, valved-stents, and associated methods and systems for their delivery via minimally-invasive surgery.

1 . A replacement valve for use within a human body comprising:
 a valve component; and   a stent component configured to house at least a portion of the valve component comprising a proximal end and a distal end, the stent component further comprising:
 a lower anchoring crnwn comprising an at least partly conical body, wherein the lower anchoring crnwn defines the proximal end of the stent component; 
   an upper anchoring crown in communication with the lower anchoring crown and comprising an at least partly conical body, wherein the conical body of the lower anchoring crown slopes outwardly in the direction of the proximal end, and wherein the conical body of the upper anchoring crown slopes outwardly in the direction of the distal end;   a distal stent section comprising an at least partly conical body, wherein the distal stent section is in communication with the upper anchoring crown.
