FIELD: medicine. ^ SUBSTANCE: group of inventions relates to medical equipment. A device comprises a fluid duct with one or more microparticles and a joint integrated in the duct. The fluid flow within the joint is adjusted with a field of force. Another version of the device comprises a nozzle providing fluid flow passage through a dead leg adjoining the joint to make the microparticles escaping from the dead leg. The method involves injection of fluid with one or more radioactive microparticles into the duct comprising the joint, and adjustment of the fluid flow within the joint with the field of force. When delivering one or more substantially spherical microparticles to a subject, at least 90% of radioactive microparticles are introduced. Another version of the method involves a high-density microparticle source of high specific activity connected to a subject and the high-density microparticles of high specific activity to be delivered to the subject under source pressure in the range of 35 kPa to 207 kPa. Besides, one more version of the method implies imaging of one or more spherical microparticles for the purpose of data visualisation; and the visualised data are analysed to determine the abnormal condition. ^ EFFECT: application of said group of inventions enables effective drug microparticle target delivery by the vascular system. ^ 34 cl, 7 dwg |
