IMPLANTABLE LEFT VENTRICULAR ASSIST DEVICE AND SYSTEM FOR VENTRICULAR-ASSIST FOR USE IN PATIENTS WITH END-STAGE HEART FAILURE

摘要

The invention refers to the implantable left ventricular assist device for supporting the work of the left ventricle. The device is characterised in a working chamber is divided by a narrowed space (P) formed within the chamber into two connected spaces in the form of a smaller chamber and a larger chamber, which are inflated and deflated with gas forming a valve balloon (1) and a ventricular balloon (2). The variable volume of valve balloon (1) is adapted to the to the anatomy of the mitral valve annulus, and the variable volume of the ventricular balloon (2) is adapted to the anatomy of the left ventricle. Inside the working chamber there is a pneumatic supply pipe through which gas is supplied and discharged to/from space of the chambers The present invention refers to the system for ventricular assist with said left ventricular assist device and known suction and discharge device for inflation and deflation of the chambers and a control system for controlling the mode of gas flow into the working chamber.
