Claim 0:
1. A device for ventricular emergency support of a treated patient, the device comprising:
a first flexible catheter with a variable transversal section, the first catheter comprising:
an elastic duct for an inlet of blood into a blood flow of the treated patient, the elastic duct being configured to vary an amplitude of a transversal section of the elastic duct in proportion to a quantity and to a pressure of the blood introduced in the blood flow of the treated patient; and
a first extremal balloon configured for controlled occlusion of an ascending aorta of the treated patient, the first extremal balloon having, in an inflated condition, an umbrella-shaped form including shaped loops configured for a reflux of the blood inserted into the elastic duct in a natural direction of the blood flow of the treated patient;

a first pump coupled to the first catheter for the aspiration and contemporary input of equivalent blood quantities into a blood circle of the treated patient;
a second flexible catheter with a fixed transversal section, provided with at least two second extremal balloons, the second flexible catheter being spaced between the at least two second extremal balloons, for the controlled occlusion of the inferior vena cava and of the superior vena cava of the treated patient;
a second pump coupled to the first and second catheter for inflating and deflating the first and second extremal balloons of the first and second catheter; and
an electronic control unit for adjusting and controlling operational parameters of the first and second pump, and for detection of cardiac parameters of the treated patient.
