Abstract
A mitral valve annuloplasty tube and method for implanting the same to treat mitral valve regurgitation by establishing new mitral valve annulus. The method comprising of cutting and detaching the leaflets of a mitral valve and displacing them to a different location, preferably to an upstream location of the blood flow, in order to compensate for the height of the valve prolapse. The displacement zone being filled with the present annuloplasty tube.
Claims20
An annuloplasty tube for repairing mitral valve regurgitation in patients with heart valve prolapse, said annuloplasty tube comprising:
- a bio compatible tube having a top end, a bottom end and a height;
- the bottom end is shaped and sized to attach to the annulus of a mitral valve;
- the top end is shaped and sized to receive the detached leaflets of a mitral valve;
- the height of said tube is substantially the same as the predetermined height of a prolapse,
- whereby the leaflets of the mitral valve are cutout circumferentially and are separated from the native annulus, said cutout valve is then secured to the top end of the annuloplasty tube, whereby the valve is displaced to a different height than that of native annulus.
The annuloplasty tube of claims of 1, further comprising a securing means selected from the group consisting of sutures, staples, and mechanical fasteners.
A method of repairing mitral valve regurgitation in patients with heart valve prolapse, said method comprising:
- cutting and detaching the anterior and posterior mitral leaflets circumferentially all the way around from a native annulus;
- determining the height of the prolapse;
- displacing the detached leaflets to a height above the native annulus in order to match the height of the prolapse and to cause the leaflets to co-apt at the same plane, said height defining a new height;
- filling the space between the native annulus and the new height with an annuloplasty tube, said tube having a top end and a bottom end;
- securing the bottom end of the tube to the native annulus;
- connecting an annuloplasty ring to the top end of the tube;
- and
- securing said leaflets to the ring at the top end,
- whereby the tube height corrects the prolapse so that the two leaflets touch each other.
