摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine and may be used in retrograde X-ray endoscopic diagnostic and therapeutic procedures. A device consists of a catheter and a built-in flexible rod. The catheter and rod are mounted in a working channel of the endoscope. The endoscopic catheterisation of the deformed sinuate bile ducts is enabled through a duodenum and accompanied by transpapillary X-ray diagnostic and therapeutic interventions with using a catheter of a graduated internal diameter to be lowered in one point provided with an elastic cuff peripherally fixed in a lowering point and having a hole formed in the centre of lowering. The provided flexible rod having on its distal side is equipped with a calibrated rod, a drill and a cone to cover the hole in the graduated internal diameter of the catheter with making a contrast substance flowing into the hole onto the catheter in the centre of lowering of the extended cuff to an internal diameter of a choledoch duct by pressure of the contrast substance and providing the contrast substance outflow closing into the duodenum. Further, the flexible rod opens the contrast substance passage by the cone through the catheter under pressure into the deformed bile duct. From the proximal side of the catheter, there is a control handle with a port, the in-built rod with a handle with an attached drill on the distal end for the purpose of flexibility.EFFECT: facilitated contrast of the deformed bile ducts in transpapillary X-ray diagnostic and therapeutic interventions, provided optimal conditions for catheterisation of the deformed duct strictures reducing a radiation dose for the patient and medical personnel, enhancing minimally invasive surgery ensuring economic effect due to contrast substance saving.Изобретение относится к медицине и может быть использовано в ретроградных рентгенэндоскопических методах диагностики и лечения. Устройство состоит из катетера и расположенного внутри него гибкого стержня. Катетер
