Abstract
In various embodiments, provided herein are methods, devices and systems to optimize annular orientation of transcatheter valves and thereby facilitate transcatheter aortic valve replacement in the setting of challenging cardiovascular anatomy. These methods, devices and systems are used to treat patients with valvular diseases.
Claims24
A device configured to receive a self-expandable or balloon-expandable replacement heart valve for transcatheter valve replacement, comprising:
- a ring-shaped article comprising a stent frame, the entire exterior surface of the stent frame being covered with a hollow external layer,
- wherein the ring-shaped article comprises an outside surface corresponding to an outside surface of the hollow external layer,
- wherein the outside surface comprises an inward surface area that faces toward the center of the ring-shaped article and forms a center hole,
- wherein the outside surface comprises an outward surface area that faces away from the center hole of the ring-shaped article and forms a periphery,
- wherein the ring-shaped article has a compressed status and an expanded status,
- wherein when the ring-shaped article is expanded, the center hole is configured to fit and receive a replacement heart valve configured to anchor to the center hole of the ring-shaped article, and the periphery is configured to mould to a native anatomy of a heart valve peri-annular region, cardiovascular structure or chamber, and
- wherein the ring-shaped article's height is configured to be less than a replacement heart valve's height.
4 more elements
A system for transcatheter valve replacement, the system comprising:
- a ring-shaped article comprising a hollow fabric and/or plastic material inflatable with air, fluid, or a plastic resin,
- wherein the ring-shaped article comprises an outside surface,
- wherein the outside surface comprises an inward surface area that faces toward the center of the ring-shaped article and forms a center hole,
- wherein the outside surface comprises an outward surface area that faces away from the center hole of the ring-shaped article and forms a periphery,
- wherein the ring-shaped article has a compressed status and an expanded status, and
- wherein when the ring-shaped article is expanded, the center hole is configured to fit and receive a replacement heart valve, and the periphery is configured to mould to a native anatomy of a heart valve peri-annular region, cardiovascular structure or chamber;
- a first delivery catheter configured to deploy the ring-shaped article into the heart valve peri-annular region;
- and
- a second delivery catheter configured to deploy the replacement heart valve into the center hole of the ring-shaped article.
