Abstract: The present invention relates to a device (100) wearable at a user's neck, which device (100) comprises:—a main body (10) provided with movable pushing means (11),—a control unit (20) configured to receive as input data associated with the user's heart rate and to generate a corresponding output signal (20?), wherein said output signal (20) determines a pulsating movement of said pushing means (11) according to the heart rate and wherein said pushing means (11) is positioned so as to compress and decompress the neck at the jugular veins.

Abstract: An implantable device for the treatment of hydrocephalus syndrome, characterized by a mechanical passive valve device designed to move the cerebrospinal fluid in the cranial site of the patient, comprising a cylindrical body, a piston, and a special spring exhibiting a non-linear characteristic and suitable for applying a force on the piston such that, when the pressure of the cerebrospinal fluid acting on the two opposite faces of the piston exceeds a certain value, a rapid displacement of the piston in the cylindrical body takes place due to the non-linear characteristic of the spring, with consequent aspiration, by the same piston, of a greater quantity of cerebrospinal fluid contained in the ventricle and, when the pressure of the cerebrospinal fluid falls below a certain value, the piston reacts and moves rapidly in a direction opposite to the first, so as to feed into the ventricle the cerebrospinal liquid previously aspirated.

Abstract: Implantable device or the treatment of hydrocephalus in a patient, comprising movement means designed to move the cerebrospinal fluid in the patient's skull to control the intracranial pressure; an assembly consisting of a rotary volumetric micropump; a catheter connected at one extremity to the micropump; and a bag fitted at the other extremity of the catheter and designed to contract and expand, wherein said assembly is filled with a given volume of a service fluid which remains constant over time, and wherein electronic monitoring and control means are designed to process the values (Pmis), as detected by a sensor of the instant pressure of cerebrospinal fluid and to generate a corresponding control signal which in turn drives the micropump and consequently controls the contraction and expansion of the bag so that the amplitude of the variable component of the intracranial pressure due to the cardiac cycle is minimized.
