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

A replacement valve for use within a human body comprising:

• a stent component comprising a first end and a second end and 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 comprising
• a third stent section in communication with the second stent section and housing at least a portion of a valve component of the replacement valve, and
• a fourth stent section defining an at least partly conical body, wherein the fourth stent section defines the second end and comprises valve stabilization arches for orienting the replacement valve longitudinally within an aorta/aortic annulus for preventing tilting of the replacement valve when implanted;
• wherein each valve stabilization arch has a first end in communication with the third section, a second end in communication with the third section, and an apex at the second end of the stent component.

A replacement valve for use within a human body comprising:

• a stent component comprising a first end and a second end, 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 comprising
• a third stent section in communication with the second stent section and housing at least a portion of a valve component of the valve component of the replacement valve, and
• a fourth stent section defining an at least partly conical body, wherein the fourth stent section defines the second end and comprises exactly three valve stabilization arches for orienting the replacement valve longitudinally within an aorta/aortic annulus for preventing tilting of the replacement valve when implanted.
