摘要：
The invention relates to the field of medical devices and can be used in urology for drainage of the upper urinary tract. Utility model increases to 45-70% duration of use of the stent patient and significantly improves the usability of the stent patient and physician through more rare replacement of one stent to another, and expands the arsenal of technical means that may be used as a ureteral stents in plan and especially in emergency situations. This is achieved by the fact that the ureteral stent formed in a tube of polymeric bioinert memory material, with lateral perforations, a linear portion and a clamp at each end of the tube, the stent is made collapsible, in which each locking member and coupled thereto linear section of the stent formed of a tube 1 with an external diameter of not less than 2.0 mm, each linear segment comprising on the outside surface of the retainer is not connected to the same end of the thread is not less than 10 mm, the coupled a proximal retainer linear portion of the stent has a length of at least 210 mm, and the stent further comprises a coupler formed from a tube 2 of length at least 20 mm with an external diameter of not more than 4 mm with a reciprocal thread on the inner surface, the length of each linear stent sections , the coupling length and the length of each thread are chosen so that when creating a threaded joint length of at least 5 mm between the threads on each of the linear sections and corresponding thread on the coupling length at the linear portion of the stent was harvested 2 20-320 mm, and the perforations are made along the entire length of the tube 1 except for the threads.Полезная модель относится к области изделий медицинского назначения и может быть использована в урологии для дренирования верхних мочевыводящих путей. Полезная модель увеличивает на 45-70% продолжительность использования установленного стента пациентом и существенно повышает удобство использования стента пациентом и врачом за счет более редк
