INTERMITTIERENDER VERSCHLUSS DES CORONAR-SINUS DURCH DRUCKEINWIRKUNG.
摘要
A multi-lumen catheter with an end inserted into the coronary sinus of a heart includes a balloon inflation lumen connected to a pump, and a lumen open to the sinus for blood pressure sensing by a controller. For each period of occlusion, the controller estimates a plateau level of the fluid pressure by use of exponential curve fitting, and suffers an occlusion interruption signal before that plateau is reached. The next period of occlusion is initiated at a time determined by flow signals of fluid in the sinus during the period of occlusion interruption.
