Abstract
Изобретение относитс к области медицины, в частности к баллонном катетерам. Цель изобретени - равномерное давление на стенки протеза при установке его в кровеносном сосуде. Баллонный катетер содержит надувные наружную 3 и внутреннюю 2 трубки с тканевой оболочкой 4 между ними. Тканева оболочка 4 выполнена из нераст гивающегос материала с продольными гофрами, благодар которым при раздувании происходит равномерное распределение давлени на стенки протеза. 3 ил.This invention relates to the field of medicine, in particular to balloon catheters. The purpose of the invention is uniform pressure on the walls of the prosthesis when it is installed in a blood vessel. The balloon catheter contains inflatable outer 3 and inner 2 tubes with a tissue sheath 4 between them. The fabric shell 4 is made of a non-expandable material with longitudinal corrugations, due to which, when inflation occurs, a uniform distribution of pressure on the walls of the prosthesis occurs. 3 il.

Изобретение относитс к медицинской технике, а именно к устройствам, обеспечивающим расширение трубчатых органов,The invention relates to medical technology, namely to devices for expanding tubular organs,
Цель изобретени - равномерное давление на стенки протеза при установке его в кровеносном сосуде.The purpose of the invention is uniform pressure on the walls of the prosthesis when it is installed in a blood vessel.
На фиг с 1 представлена схема баллонного катетера, исходное положение; на фиг. 2 - то же, расправленное положение; на фиг„ 3 - вид А на фиг о 2.Fig with 1 shows a diagram of a balloon catheter, the initial position; in fig. 2 - the same, straightened position; in Fig „3 - view A in fig about 2.
Баллонный катетер содерж-ит полую гибкую трубку 1 с заглушенным концом с баллоном на этом конце, выполненным из внутренней 2 и наружной 4 надувных трубок с тканевой оболочкой 4 между ними, дл уменьшени трени между которыми введена смазка 5.Тканева оболочка 4 выполнена из нераст гивающегос материала с продольными гофрами о Концы трубок 2 и 3 и оболочки 4 с гофрами закреплены на трубке 1 так, что между трубкой 1 и раст гивающейс трубкой 2 образуетс полость, сообщающа с с каналом трубки 1 через отверсти 6„The balloon catheter contains a hollow flexible tube 1 with a plugged end with a balloon at this end, made of inner 2 and outer 4 inflatable tubes with tissue sheath 4 between them, to reduce friction between which lubricant 5 is inserted. The tissue sheath 4 is made of non-expandable material with longitudinal corrugations o The ends of the tubes 2 and 3 and the shell 4 with corrugations are fixed on the tube 1 so that between the tube 1 and the stretching tube 2 a cavity is formed, which communicates with the channel of the tube 1 through the holes 6
Баллонный катетер действует следующим образом оThe balloon catheter operates as follows
По трубке 1 в полость баллона поступает жидкость под давлением и расправл ет баллон до его предельного размера, ограниченного оболочкой 4 с расправленными гофрами. При раздувании баллона в трубчатом органе, имеющем размер, меньший размера баллона с расправленной оболочкой 4, благодар ее укладке в виде продольных гофр происходит равномерное давление баллона на стенки трубчатого органа При сбрасывании давлени жидкости баллон возвращаетс в исходное положение, При этом в результате гофрированного закреплени Through the tube 1, the liquid enters the cavity of the container under pressure and expands the cylinder to its limiting size, limited by the shell 4 with the expanded corrugations. When the balloon is inflated in a tubular organ having a size smaller than the balloon with the unfolded sheath 4, due to its packing in the form of longitudinal corrugations, a uniform pressure of the balloon against the walls of the tubular organ occurs. When the fluid pressure drops, the balloon returns to its original position.
оболочки 4 в концах баллона происходит укладка тканевой оболочки с образованием исходных гофр,the shell 4 at the ends of the balloon is laying the tissue shell with the formation of the initial bumps,
Пример У больного с сужением общей и наружных подвздошных ар0 терий внутрь артерии ввод т в сжатом виде трубчатый протез и с помощью баллонного катетера, в свою очередь введенного внутрь протеза, расправл ют и усаживают протез вExample In a patient with a narrowing of the common and external iliac arteries, a tubular prosthesis is inserted into the artery in a compressed form, and using a balloon catheter, in turn, inserted inside the prosthesis, the prosthesis is straightened and the prosthesis is seated
5 стенку артерии, улучша кровоток„ Баллонный катетер обеспечивает давление на стенки протеза, необходимое дл преодолени сопротивлени стенок артерии о Продольные гофры5 artery wall, improving blood flow; Balloon catheter provides pressure on the walls of the prosthesis necessary to overcome the resistance of the artery walls. Longitudinal corrugations
0 обеспечивают равномерное давление и исключают одностороннее расправление и усадку протеза. Смазка уменьшает веро тность разрушени трущихс между собой трубок и улучшает услови укладки оболочки продольными гофрами , что повышает проникающую способность баллона и, следовательно,его эффективность„0 provide uniform pressure and exclude unilateral expansion and shrinkage of the prosthesis. The lubricant reduces the likelihood of pipes rubbing together and improves the conditions for laying the shell with longitudinal corrugations, which increases the penetrability of the balloon and, consequently, its efficiency.
