Patent

CA 2617154

Devices and methods are disclosed for the control of blood perfusion pressure within a blood vessel that undergoes arterialization. A cannula is introduced that contains a stenosis that either resorbs or is removed in time, allowing a gradual increase in blood pressure between two blood passages connected at either ends of the cannula. Particular emphasis has been made with the use of the cannula for the vessels in the heart.

L'invention concerne des dispositifs et des procédés de régulation de la pression de perfusion sanguine dans un vaisseau sanguin soumis à une artérialisation. Ces procédés consistent à introduire une canule contenant une sténose qui soit se résorbe, soit est retirée en temps utile, de manière à permettre une augmentation graduelle de la pression sanguine entre deux passages de sang reliés à chaque extrémité de la canule. L'invention porte en particulier sur l'utilisation de cette canule pour les vaisseaux cardiaques.
