FIELD: medical equipment. ^ SUBSTANCE: device is applied onto blood vessel in such a way that the device together with the vessel forms new channel, which combined device can be used for curing (shunting) for hydrocephaly when there is need to create channel for passing spinal fluid from catheter passing fluid into deep neck vein without having contact between device, catheter (or any other foreign body) and blood current in vessel. Device for passing fluid from catheter to blood vessel together with mentioned blood vessel forms channel at part of length of the blood vessel. Channel goes in parallel to the vessel. Blood current, which goes through blood vessel, doesn't have contact either with device or with mentioned catheter. Applicator for application onto blood vessel of the device for passing fluid from fluid-passing catheter to blood vessel has frame part made for holding infusion needle, punching needle fastened to applicator by means of lock, tube and glue supplying tube connected with syringe filled with glue. Method of application of the device for passing fluid from passing catheter to blood vessel has aid for fixing to applicator by means of glue-supplying tube and infusion needle. Part of neck vein of patient is released by means of slight cutting. Then that part is lifted and fixed. Double folded ligature, in which ligature the ligature strands are used, is disposed around supposed point of puncture. Then wall of vein is lifted by means of surgical needle to make punching easier. Punching needle is removed and infusion needle is introduced into vein simultaneously with pulling ligature strands at the direction being opposite to direction of introduction of infusion needle to make passage of device easier. Then ligature is tied up. Additional ligature is attached to hole fro stitching to fix wall of vessel to device near mentioned hole. Biological glue is introduced from syringe filled with glue. After glue hardened, infusion needle is removed and pulled back completely for separation of device from application. Then device is connected with catheter which comes from valve of shunt. ^ EFFECT: reduced danger of thrombosis. ^ 15 cl, 10 dwg |
