  • the present invention relates to the treatment of patients with congestive heart failure, and more particularly to a device for partitioning the ventricles of a heart failure patient.
  • Heart failure is a group of diseases caused by the heart's structural or functional abnormalities that result in a decrease in the heart's ability to receive blood (relaxation) or squeezing pumps (contraction), resulting in poor blood supply to body tissues. .
  • Heart failure is characterized by gradual dilation of the heart, especially the left ventricle. As the heart expands, the heart becomes more difficult to pump blood efficiently through the heart beat.
  • Surgical treatment is a limited use in severe heart failure that usually does not respond well to medical treatments such as medication.

  • a patient with severe dysfunctional heart failure who waits for a period of time, such as viral acute myocarditis, may have resuscitation when a mitral valve leaks severely due to heart failure.

La présente invention concerne un dispositif de cloisonnement ventriculaire comprenant une poche pouvant être gonflée pour passer d'un état plié, permettant à une canule de passer à travers celle-ci, à un état gonflé, permettant aux ventricules d'un patient d'être cloisonnés en formant une partie utilisée et une partie non utilisée ; un fil gonflant couplé à la surface interne de la poche de sorte à faire passer la poche de l'état plié à l'état gonflé ; et un moyen de support fixé au centre de la poche, s'étendant sur une paroi ventriculaire, et installé sur la paroi ventriculaire. Le dispositif de cloisonnement ventriculaire selon la présente invention peut cloisonner des ventricules en formant une partie utilisée et une partie non utilisée afin de réduire le volume des ventricules et les contraintes appliquées sur les ventricules. Ainsi, le dispositif de cloisonnement ventriculaire selon la présente invention peut augmenter la fraction d'éjection du cœur d'un patient atteint d'une insuffisance cardiaque congestive.
