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 45-75% 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 in that, in a 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 the distal clamp and connected thereto linear stent area is not less than 20 mm in length made of tubes 1 with an external diameter of not more than 4.0 mm, the proximal clamp and connected thereto linear portion of the stent is not less than 220 mm made of two tubes with an external diameter enee 2.0 mm to enable telescoping connection tubes 1 and 2, wherein the stent further comprises an elastic sleeve, formed as a tube length of at least 3 mm and 20 enable the fixation of the linear portion in the assembled stent length when the coupling arrangement of the telescopic coupling place tubes, wherein the length of each of the linear portions at the disassembled stent is selected so that when the telescopic joint length of at least 10 mm length of the linear portion of the stent was harvested from 220-320 mm.Полезная модель относится к области изделий медицинского назначения и может быть использована в урологии для дренирования верхних мочевыводящих путей. Полезная модель увеличивает на 45-75% продолжительность использования установленного стента пациентом и существенно повышает удобство использования стента пациентом и врачом за счет более редкой замены одного стента на другой, а также расширяет арсенал технических средств, которые могут быть использованы в качестве мочеточниковых стентов в плановых и осо
