摘要:
Dilation system comprising a dilatable device made from a thermoplastic material having a closed end and an open end, the open end being connected to a pressure source, said dilatable device being able to be inflated by the application of pressure and deflated by loss of pressure to retain almost its original dimension, wherein the dilatable device has at least two layers (121, 161) of said thermoplastic material and sandwiched in between said two layers (121, 161) of thermoplastic material a braided mesh (41) made from a multitude of metal wires, wherein the braided mesh (41) of the inflatable device in the non- pressurized state has a braiding angle (γ) of less than 54.7° in at least one portion of the inflatable device and a braiding angle (α) of more than 54.7° in at least one other portion of the inflatable device such that under internal pressure the braiding angle (γ) in the at least one portion of the inflatable device will increase to an angle (δ) under increase of diameter and reduction of length and the braiding angle (α) in the at least one other portion of the inflatable device will decrease to an angle (β) under reduction of diameter and increase of length, the length increase in the at least one other portion compensating for the length reduction in the at least one portion.Sistema de dilatación que comprende un dispositivo dilatable hecho de un material termoplástico que tiene un extremo cerrado y un extremo abierto, el extremo abierto se conecta a una fuente de presión, el dispositivo dilatable es capaz de ser inflado por la aplicación de presión y desinflado por la pérdida de presión para retener casi su dimensión original, en donde el dispositivo dilatable tiene al menos dos capas (121, 161) del material termoplástico e intercalada en medio de las dos capas (121, 161) de material termoplástico una malla trenzada (41) hecha de una multitud de alambres metálicos, en donde la malla trenzada (41) del dispositivo inflable en el estado no presur
