摘要
Methods and systems for regulating aortic regurgitation during aortic valve replacement or repair procedures utilize a temporary aortic valve (TAV) catheter and a controller. The temporary aortic valve catheter has an expandable occlusion device which can partially occlude the aortic lumen during ventricular diastole with a lesser occlusion during ventricular systole. Exemplary balloon structures include multiple, independently inflatable balloons which are inflated in synchrony with the cardiac cycle by the controller. By controlling aortic regurgitation, the repair or replacement protocols can be conducted with less interference from blood flow.
