摘要：
FIELD: medicine.SUBSTANCE: inventions relate to medical equipment, specifically a medical device comprising a hollow structure and delivering a catheter for treating blood vessel segments of the vascular system. Medical device for occluding or blocking segments of a blood vessel comprises a catheter and a compressed hollow metal structure attached to the catheter. Metal structure, when expanded, comprises one segment having a wall with an inner surface defining a cavity, and an outer surface with an opening defined by the wall, which allows passage of a fluid into the cavity. Cavity of the hollow metal structure and the lumen of the catheter can be connected by a fluid, and the passage of fluid from the catheter into the cavity of the hollow metal structure results in its expansion. Medical device is configured such that the expanded hollow metal structure and catheter can be disconnected. Expanded hollow metal structure has sufficient rigidity to remain in the expanded state when it is implanted in a living organism in an unclosed configuration. In accordance with a second embodiment of the medical device for occluding or blocking segments of a blood vessel, the compressed hollow metal structure and the catheter are connected by a friction joint, without an adhesive joint, soldering or welding, wherein the metal structure has a neck which defines the opening. According to a third embodiment, the medical device for occluding or blocking blood vessel segments further comprises a component configured to separate the expanded hollow metal structure and the catheter, wherein the actuation of the component cuts or tears a portion of the expanded hollow metal structure, which leads to the separation of the expanded hollow metal structure and the catheter. According to a fourth embodiment, the medical device for occluding or blocking blood vessel segments further comprises a component configured to separate the expanded hollow metal structure and the catheter, the componen
