Stents, valved-stents and methods and systems for delivery thereof

Abstract

Embodiments of the present disclosure are directed to stents, valved-stents, (e.g., single-stent-valves and double stent/valved-stent systems) and associated methods and systems for their delivery via minimally-invasive surgery. The stent component comprises a first stent section ( 102 ) a second stent section ( 104 ) a third stent section ( 106 ) and a fourth stent section ( 108 ).

What is claimed: 
     
         1 . A replacement valve for use within a human body comprising:
 a stent component comprising a first end and a second end wherein the first end is the proximal end of the replacement valve and the second end is the distal end of the replacement valve, the stent component further comprising a plurality of sections including:   a first stent section defining an at least partly conical body, wherein the first stent section defines the proximal end of the stent component;   a second stent section in communication with the first stent section and defining an at least partly conical body, wherein the conical body of the first stent section slopes outwardly in the direction of the first end, and wherein the conical body of the second stent section slopes outwardly in the direction of the second end;   a distal stent section defining an at least partly conical body, wherein the distal stent section defines the second end.
