Abstract
Devices, systems, and methods for an implantable heart-valve adapter that enables compact and secure delivery into the heart and allows for convenient control of both the adapter during implantation as well as the expansion and retraction of the valve when implanted, removed, or replaced.
Claims18
An implantable heart-valve adapter apparatus, comprising:
- a tubular braided frame, wherein the tubular braided frame comprises an inflow end and an outflow end;
- wherein the tubular braided frame extends out from the inflow end to form at least one flange;
- and
- wherein the tubular braided frame extends out from the outflow end to form engagement attachments comprising a leaflet clip and two U-shaped stabilization anchors, wherein the engagement attachments are integrally formed with the tubular braided frame as a single component, wherein the leaflet clip is disposed between the two U-shaped stabilization anchors, wherein when deployed in a native mitral valve comprising a native mitral annulus and one or more native leaflets, the leaflet clip engages behind the one or more native leaflets and the two U-shaped stabilization anchors extend towards the native mitral annulus behind the one or more native leaflets.
1 more element
An implantable heart valve-adapter delivery system, comprising:
- an implantable heart-valve adapter comprising a tubular braided frame, wherein the tubular braided frame comprises an inflow end and an outflow end;
- wherein the tubular braided frame extends out from the inflow end to form at least one flange;
- and
- wherein the tubular braided frame comprises engagement attachments extending out from and integrally formed with the outflow end, the engagement attachments comprising a leaflet clip and two U-shaped stabilization anchors, wherein the leaflet clip is disposed between the two U-shaped stabilization anchors, wherein when deployed in a native mitral valve comprising a native mitral annulus and one or more native leaflets, the leaflet clip engages behind the one or more native leaflets and the two U-shaped stabilization anchors extend towards the native mitral annulus behind the one or more native leaflets;
- a delivery component, comprising one or more suture lines connected on a first end to the engagement attachments;
- wherein the one or more suture lines connects on a second end to the delivery component.
3 more elements
A method for percutaneous deployment and placement of an implantable heart-valve adapter, comprising:
- an implantable heart-valve adapter and a delivery component;
- wherein the implantable heart-valve adapter comprises a tubular braided frame, an inflow end and an outflow end;
- wherein the tubular braided frame extends out from the inflow end to form at least one flange;
- and
- wherein the tubular braided frame extends out from the outflow end to form engagement attachments comprising a leaflet clip and two U-shaped stabilization anchors, wherein the leaflet clip is disposed between the two U-shaped stabilization anchors, wherein the tubular braided frame and at least one of the two-shapted stabilization anchors are integrally formed as a single component;
- wherein the delivery component comprises one or more suture lines;
- wherein the one or more suture lines goes through the engagement attachments and connects to the delivery component;
- percutaneously placing the implantable heart-valve adapter into one of a vein or an artery;
- delivering the implantable heart-valve adapter to a native heart valve;
- placing the implantable heart-valve adapter in the position of the native heart valve;
- and
- expanding the engagement attachments, wherein when deployed in a native mitral valve comprising a native mitral annulus and one or more native leaflets, the leaflet clip engages behind the one or more native leaflets and the two U-shaped stabilization anchors extend towards the native mitral annulus behind the one or more native leaflets.
