Novel apparatus and minimally invasive methods to treat atrioventricular valve regurgitation that is a result of tethering of chordae attaching atrioventricular valve leaflets to muscles of the heart, such as papillary muscles and muscles in the heart wall, thereby restricting the closure of the leaflets. Catheter embodiments for delivering and positioning chordal severing and elongating instruments are described.

L'invention porte sur un nouvel appareil et des procédés faiblement invasifs de traitement de la régurgitation de la valvule auriculo-ventriculaire qui résulte de la rétention des cordages tendineux attachant les feuillets de la valvule auriculo-ventriculaire à des muscles du coeur tels que les muscles papillaires et les muscles de la paroi du coeur qui restreint la fermeture des feuillets. L'invention porte également sur des exécutions de cathéters permettant de mettre en place et positionner des instruments de sectionner et d'étirer les cordages tendineux.
