There is described a device for cardiocirculatory assistance, also named ventricular assist device, comprising a haematic pump (50) with pump body (7) having an inner space (21) defined by a rigid structure (51) and a pair of mobile membranes (16, 17) alternatively driven in opposite directions by alternatively positive pressure and negative pressure gas supplied in recesses (19, 20) surrounding the two membranes by means of an external pneumatic force generating unit (1). This device achieves excellent operation results while maintaining reduced size and reduced weight (Fig. 1). |
