The Mitral Butterfly® implant facilitates reconstruction of the mitral valve for mitral valve prolapse. It is an innovative transvascular implant with a unique physiological design that emulates conventional chordal repair. The product provides for a minimally invasive procedure with no need for major surgery.
Mitral Butterfly® consists of a nitinol-stent and PTFE yarns which act as artificial chordae. Upon deployment, the device spreads its nitinol wings above the prolapsing leaflet segment. The PTFE yarns replace broken chordae, prevent prolapse of the diseased parts and guarantee a functional valve. The PTFE filaments extend to a hook in the ventricle, mimicking a papillary muscle. The mitral annulus remains unaffected and no unintentional forces strain the myocardium.
Currently, Mitral Butterfly® is in the preclinical testing stage. Proof of concept was verified using passively perfused porcine hearts with native valves and after manually cutting the chordae.
