The cardiovascular device (1) comprises a diaphragm assembly designed to be inserted into a ventricular cavity (VS) substantially transverse in order to reduce its volume, said diaphragm assembly having a peripheral edge (2B) that can be sealingly engaged on the walls (5) of the cavity 7 and being alternately driven between an active blood thrust position and an inactive position, said assembly being at least partially deformable in response to contractions of the walls (5) and comprising a balloon-shaped elastic body (2; 100; 200; 300; 400) which has an external surface (2A; 103) that defines and encloses an internal cavity (CI; CI2) and which can be configured between a gathered position of minimum bulk, an everted position of maximum bulk and vice-versa, at least one mobile portion (3; 3′) of the peripheral surface which is disposed transverse/diagonal and which is surrounded by the peripheral edge and at least one aperture (3A) for access from the outside to the internal cavity (CI; CI2).
A61M 60/148 - Implantable pumps or pumping devices, i.e. the blood being pumped inside the patient’s body implantable via, into, inside, in line, branching on, or around a blood vessel in line with a blood vessel using resection or like techniques, e.g. permanent endovascular heart assist devices
A61M 60/295 - Balloon pumps for circulatory assistance
