Abstract
A collapsible prosthetic heart valve includes a stent and a valve assembly. The stent includes an annulus section and at least one foldable section. The stent is movable between an unfolded condition in which the foldable section is longitudinally spaced from the annulus section, and a folded condition in which the foldable section is at least partially positioned radially adjacent the annulus section. The valve assembly is positioned within the annulus section of the stent in the folded condition of the stent.

(canceled)
A prosthetic heart valve, comprising:
- a stent extending in a longitudinal direction and including an outer stent section and an inner stent section, the stent having an expanded configuration and a collapsed configuration, the outer stent section at least partially overlapping with the inner stent section in the expanded configuration;
- and
- a valve assembly coupled to the inner stent section.
An assembly, comprising:
- a prosthetic heart valve including:
- a stent extending in a longitudinal direction and including an outer stent section and an inner stent section, the stent having an expanded configuration and a collapsed configuration, the outer stent section at least partially overlapping with the inner stent section in the expanded configuration;
- and
- a valve assembly coupled to the inner stent section;
- and
- a delivery device having a valve support for supporting the prosthetic heart valve and a sheath slidable relative to the valve support between a first position in which the sheath covers the prosthetic heart valve and maintains the prosthetic heart valve in the collapsed configuration, and a second position in which the sheath exposes the prosthetic heart valve for deployment,
- wherein the outer stent section is configured to automatically fold relative to the inner stent section upon deployment of the prosthetic heart valve from the delivery device.
