A method for securing a transcatheter heart valve prosthesis within a heart, the transcatheter heart valve prosthesis comprising a supra-annular sealing collar and a sub-annular sealing collar, each of said collars connected to a collapsible flow control sleeve that provides a reciprocating closable channel from a heart atrium to a heart ventricle, each of said collars comprised of a substantially flat braided or laser-cut wire frame covered with a biocompatible material and each having a central aperture, the collapsible flow control sleeve connected at an upper end to an inner perimeter of the central aperture of the supra-annular sealing collar, the collapsible flow control sleeve connected at a middle section to an inner perimeter of the central aperture of the subannular sealing collar, and the collapsible flow control sleeve extending beyond the central aperture of the sub-annular sealing collar and having a lower end positioned with the ventricle of the heart, the method comprising the steps:
- (i) piercing the supra-annular sealing collar of the transcatheter heart valve prosthesis using a pin delivery tool;
- (ii) anchoring a pin into the sub-annular sealing collar of the transcatheter heart valve prosthesis using the pin delivery tool;
- (iii) detaching the pin from the pin delivery tool and withdrawing the pin delivery tool, said pin having a securement wire attached thereto, the securement wire disposed within an inner lumen of the pin delivery tool, wherein the securement wire is revealed by withdrawal of the pin delivery tool, and wherein the pin delivery tool is withdrawn above the supra-annular sealing collar;
- (iv) tensioning the securement wire to draw the sub-annular sealing collar toward the supra-annular sealing collar by reducing the length of the securement wire between the sealing collars;
- (v) fastening the securement wire to the supra-annular sealing collar and trimming the securement wire to disconnect the securement wire from the pin delivery tool;
- and
- (vi) repeating steps (i)-(v) to deploy from 2-12 pins and securement wires in the transcatheter heart valve prosthesis.
A transcatheter heart valve replacement, comprising:
- (i) a supra-annular sealing collar and (ii) a sub-annular sealing collar, each of said collars connected to (iii) a collapsible flow control sleeve that provides a reciprocating closable channel from a heart atrium to a heart ventricle, each of said collars comprised of a substantially flat braided or laser-cut wire frame covered with a biocompatible material and each having a central aperture, the collapsible flow control sleeve connected at an upper end to an inner perimeter of the central aperture of the supra-annular sealing collar, the collapsible flow control sleeve connected at a middle section to an inner perimeter of the central aperture of the sub-annular sealing collar, and the collapsible flow control sleeve extending beyond the central aperture of the sub-annular sealing collar and having a lower end positioned with the ventricle of the heart, and (iv) from 2-12 fastening pins with securement wires, said fastening pins attached to the subannular sealing collar and said securement wires attached to the supra-annular sealing collar, wherein said fastening pins with securement wires are tensioned to compress native heart annular tissue between the collars to function as a securement and mounting mechanism.
A tricuspid valve, comprising:
- an open framed annular collar having 2-12 radial bracket supports disposed therein and connecting the open framed annular collar to a central mounting hub, an elongated axial tether having a proximal end attached to and extending away from the central mounting hub, and an elongated pliant conduit having a proximal end attached to and extending away from the open framed annular collar, with the elongated axial tether disposed within a lumen of the pliant conduit.
