METHOD FOR MAKING NEUTRON IMPLANTS Russian patent published in 2021 - IPC A61F2/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, more precisely to neurosurgery and neurology, and is intended for use in neurorehabilitation of patients with neurological diseases of various etiology using implants. To make neutron implants, a tensile layer of insulating material is created, and a tensile conductive pathway is formed on the said layer. Encapsulation of at least one of the above-mentioned conductive paths is carried out by means of an encapsulating layer containing at least one through hole. The hole is filled with an electrically conductive material, conductive paste to predetermined areas of the conductive path is applied. An electrically conductive element is inserted into a ball of electrically conductive paste. The electrical device is filled with a viscous elastomer, and the said elastomer is cured. The tensile layer with conductive paths is made by 3D printing, which includes extrusion of a non-flowing silicone elastomer, polymerization and plasma activation of the surface. The application of electrical channels is carried out by means of inkjet printing using ink in which platinum microparticles are suspended in a viscous solvent. The attachment of flexible metal wires to the contact pads is carried out by the method for point extrusion of the conductive paste, after which the flowing silicone is applied. A suspension of platinum microparticles with a diameter of 0.2-1.8 mcm in triethylene glycol monomethyl ether is used as ink.

EFFECT: method allows to expand the range of implants in order to obtain more reliable neuroprostheses, provides stable behavior during stretching in the physiological range of elastic deformation, maintains electrical functionality when exposed to physiologically significant stretches and after long deformation cycles.
