Abstract
Described is a prosthetic valve, comprising: an expandable stent including an inner lumen and having a first and a second end; and a spring attached to the first end of the expandable stent; wherein the expandable stent and the spring can expand radially to a desired diametric configuration in order to anchor the prosthetic valve at an implantation position in a body lumen. Related systems and methods.

A prosthetic valve delivery system, comprising:
- a prosthetic valve, comprising:
- an expandable stent comprising a first end, a second end, an inner lumen, and a longitudinal axis;
- and
- an expandable spring connected to the first end of the expandable stent,
- wherein a circumference of the expandable spring is perpendicular to the longitudinal axis of the expandable stent;
- and
- a sheath comprising an inner lumen,
- wherein the expandable stent is compressed into a collapsed position and restrained within the inner lumen of the sheath.
5 more elements
A method of implanting a prosthetic valve, comprising:
- inserting a delivery system with a prosthetic valve into a body lumen, the prosthetic valve comprising:
- an expandable stent comprising a first end, a second end, an inner lumen, and a longitudinal axis;
- and
- an expandable spring connected to the first end of the expandable stent,
- wherein a circumference of the expandable spring is perpendicular to the longitudinal axis of the expandable stent;
- at least partially deploying the prosthetic valve at an implantation location;
- and
- proximally pulling the prosthetic valve to engage the expandable spring with a wall of the body lumen.
