Abstract
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.
Claims20
A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
- a first surface and an opposed second surface;
- a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- and
- a superior zone and an inferior zone, the superior zone configured to reside in the plane of an annulus of the heart valve, the inferior zone extending downward from the superior zone,
- wherein the inferior zone comprises a leaflet-apposing valve body element and a leaflet surface, wherein the leaflet-apposing valve body element is configured to increase the distance between the leaflet-apposing valve body element and the leaflet surface in an expanded state.
A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
- a first surface and an opposed second surface;
- a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- and
- a superior zone and an inferior zone, the superior zone configured to reside in the plane of an annulus of the heart valve, the inferior zone extending downward from the superior zone,
- wherein the inferior zone comprises a leaflet-apposing valve body element configured to expand outward based on the motion of the heart or blood flow or pressure build-up within the heart of the patient.
