PUMPING SYSTEM, ENDOLUMINAL DEVICE AND SYSTEM FOR CREATING A TWO-WAY BLOOD FLOW

摘要

A pumping system (200) for controlling the flow of interatrial blood comprises, housed inside a container (201), a control element (30, 30', 30") of the interatrial blood flow. The control element comprises: at least one worm screw (31), the rotation of which creates a two-way flow of interatrial blood; or a pair of counter-rotating propellers (31'); or a pair of membranes (31' ' ) whose deformation creates a two-way flow of interatrial blood; or a flexible structure (31' ' ) whose change in volume within the container (201) creates a two-way flow of interatrial blood.
