Abstract[English]
Devices, systems, and methods for causing retrograde oxygenated blood flow in at least a portion of the venous system of the myocardium are disclosed. Devices and methods include a variable occluder for implantation in a coronary sinus region proximate a left atrium, wherein the variable occluder is configured to gradually increase a level of blood flow restriction over a period of days to enable a venous system of the myocardium to compensate for increased pressure caused by the gradual increase in the level of blood flow restriction. Following venous system compensation, oxygenated blood flow is shunted into the coronary sinus to cause retrograde flow of oxygenated blood in at least a portion of the venous system of the myocardium to thereby enable revascularization of the myocardium.[French]
L'invention concerne des dispositifs, des systèmes et des méthodes pour provoquer un flux sanguin oxygéné rétrograde dans au moins une partie du système veineux du myocarde. Les dispositifs et les méthodes comprennent un dispositif d'occlusion variable destiné à être implanté dans une région de sinus coronaire à proximité d'une oreillette gauche, le dispositif d'occlusion variable étant conçu pour augmenter progressivement un niveau de restriction de flux sanguin sur une période de plusieurs jours pour permettre à un système veineux du myocarde de compenser une pression accrue provoquée par l'augmentation progressive du niveau de restriction du flux sanguin. Après la compensation du système veineux, le flux sanguin oxygéné est dérivé dans le sinus coronaire pour provoquer un flux sanguin oxygéné rétrograde dans au moins une partie du système veineux du myocarde pour ainsi permettre la revascularisation du myocarde.
