Devices, Systems, and Methods for a Valve Replacement

A device for assisting the functioning of a heart valve, comprising:

• a valve assembly comprising a tubular braided frame;
• wherein the valve assembly comprises an inflow end and an outflow end;
• wherein the valve assembly comprises at least one commissure post at the outflow end;
• and
• wherein the valve assembly comprises a leaflet assembly connected to the at least one commissure post, wherein the leaflet assembly is configured to provide a seal between the inflow end and the outflow end.

A device for assisting the functioning of a heart valve, comprising:

• a tubular frame comprising an inflow end and an outflow end;
• wherein the tubular frame comprises at least one braided wire wound in a helical spiral direction;
• wherein the helical spiral direction begins at the inflow end and ends at the outflow end;
• wherein the tubular frame is configured to lengthen and compress in relation to a heart contraction.

A method of delivering a heart valve, comprising:

• advancing a catheter device for carrying a heart valve toward a mitral annulus;
• pushing the catheter device through the mitral annulus;
• deploying at least one engagement attachment from the catheter device embodiment in a ventricle;
• securing, in the ventricle, the at least one engagement attachment to at least one native leaflet;
• deploying at least one anchor from the catheter device in the ventricle;
• securing, in the ventricle, the at least one anchor to native heart tissue;
• and
• releasing, in the atrium, a flange to fit over the mitral annulus.

A method of replacing a heart valve, comprising:

• in the atrium, transeptally advancing a first catheter device towards the mitral annulus, wherein the first catheter device comprises a separable new minimum leaflet structure (MLS);
• positioning the first catheter device so that the new MLS is aligned with and proximate to the mitral annulus;
• in the ventricle, transapically pushing a second catheter device towards the mitral annulus, wherein the second catheter device is configured to remove an old MLS;
• positioning at least part of the second catheter device to transapically grasp the old MLS from the mitral annulus;
• securing and pulling, using at least part of the second catheter device, the old MLS away from the mitral annulus for transapical removal;
• and
• transeptally inserting, using the first catheter device, the new MLS into the mitral annulus.

A device for assisting the functioning of a heart valve, comprising:

• a tubular braided frame comprising an inflow end and an outflow end;
• a flange structure at the inflow end of the tubular braided frame;
• at least one anchor at the outflow end of the tubular braided frame configured to anchor to a native leaflet;
• at least one anchor at the outflow end of the tubular braided frame configured to anchor to an area adjacent to the native annulus;
• at least one commissure post at the outflow end of the tubular braided frame, wherein the commissure post extends out from the tubular braided frame;
• and
• a leaflet assembly connected to the at least one commissure post, wherein the at least one commissure post extends out from the tubular braided frame and the leaflet assembly is configured to provide a seal between the inflow end and the outflow end of the tubular braided frame.
