Devices, systems, and methods for an implantable heart-valve adapter
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.
1 . 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.
2 . The apparatus of claim 1 , wherein the tubular braided frame is constructed of one or more material that is expandable or compressible or both expandable and compressible.
3 . The apparatus of claim 2 , wherein the apparatus comprises a layer of material extending over an outside portion and inside portion of the tubular braided frame, the at least one flange, and the engagement attachments.
4 . The apparatus of claim 2 , wherein the apparatus comprises a layer of material extending over an outside and inside portion of the tubular braided frame and the at least one flange.
5 . The apparatus of claim 2 , wherein the stabilization anchors are between 120 to 180 degrees apart.
6 . The apparatus of claim 2 , wherein the tubular braided frame is a braid of one or more wires, wherein the braid of the one or more wires is either a zig-zag braid or an over-under braid, and wherein the one or more wires consists of one of: nitinol wire, stainless steel, cobalt chrome, and nylon.
7 . 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.
8 . The system of claim 7 , wherein the tubular braided frame is constructed of one or more material that is expandable or compressible or both expandable and compressible.
9 . The system of claim 8 , wherein the implantable heart-valve adapter comprises a layer of material extending over an outside portion and inside portion of the tubular braided frame, the at least one flange, and the engagement attachments.
10 . The system of claim 8 , wherein the implantable heart-valve adapter comprises a layer of material extending over an outside and inside portion of the tubular braided frame and the at least one flange.
11 . The system of claim 8 , wherein the stabilization anchors are between 120 to 180 degrees apart.
12 . 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.
13 . The method of claim 12 , wherein the tubular braided frame is constructed of one or more material that is expandable or compressible or both expandable and compressible, and wherein the apparatus comprises a layer of material extending over an outside portion and inside portion of the tubular braided frame, the at least one flange, and the engagement attachments.
14 . The method of claim 13 , wherein the vein is a femoral vein and wherein delivering the implantable heart-valve adapter to a native heart valve comprises delivering the implantable heart-valve adapter through the vena cava.
15 . The method of claim 13 , wherein the vein is a femoral vein and wherein delivering the implantable heart-valve adapter to a native heart valve comprises delivering the implantable heart-valve adapter through the vena cava and through a puncture in the atrial septum.
16 . The method of claim 13 , wherein percutaneously placing the replacement heart-valve delivery system into one of a vein or an artery consists of inserting the replacement heart-valve delivery system into one of the vein or the artery over a guidewire.
17 . The method of claim 13 , wherein the stabilization anchors are between 120 to 180 degrees apart.
18 . The method of claim 13 , wherein the tubular braided frame is a braid of one or more wires, wherein the braid of the one or more wires is either a zig-zag braid or an over-under braid, and wherein the one or more wires consists of one of: nitinol wire, stainless steel, cobalt chrome, and nylon.
