35. 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 crown comprising an at least partly conical body, wherein the lower anchoring crown 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; and a distal stent section comprising an at least partly conical body, wherein the distal stent section is in communication with the upper anchoring crown. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A system for replacing a valve within a human body comprising:
-
a delivery device; and 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 crown defining an at least partly conical body, wherein the lower anchoring crown defines the proximal end of the stent component; an upper anchoring crown in communication with the lower anchoring crown and defining 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; and a distal stent section defining an at least partly conical body, wherein the distal stent section comprises a commissural post section and stabilization arch section, wherein the commissural post section is in communication with the upper anchoring crown; and
wherein the stabilization arch section is in communication with commissural post section and defines an at least partly conical, and wherein the stabilization arch section defines the distal end;the stent component having a central, longitudinal axis and comprising at least one attachment element for removable attachment to a delivery device, wherein the at least one attachment element is located at a proximal end of the stent component, wherein the proximal end is defined as the end toward the left ventricle when delivered from a transapical approach. - View Dependent Claims (47, 48, 49, 50, 51)

52. 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 distal stent section defining the distal end and comprising a stabilization arch section and a commissural post section communicating with the stabilization arch section, the commissural post section defining supports for the valve component; a proximal anchoring section defining the proximal end; and a first crown section communicating with the distal stent section and with the proximal anchoring section, the first crown section comprising a first divergent portion that diverges outwardly in a direction towards the distal end, the first crown section having a free end. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
