Title (EN) ELASTOMERIC BALLOON SUPPORT FABRIC
(FR) TISSU DE SUPPORT ELASTOMERE POUR BALLONNET
Abstract:
(EN) Balloon catheter covers are elastic fabric structures of interconnected yarns, the structure having a high degree of stretch and recovery in the circumferential direction with little change in dimension in the longitudinal direction during multiple pressurization cycles over full range of inflation and deflation of the balloon catheter. The covers have longitudinal yarns positioned at about zero degrees to the balloon axis and reversibly-stretchable, circumferential yarns positioned at a high angle Ø to the axis. A method for making the balloon catheter covers allowing nearly orthogonal placement of circumferential and longitudinal yarns involves triaxial braiding a minimum number of elastomeric braid yarns with multiple axial yarns to provide maximum convergence angle (approaching 90 degrees).
(FR) Des enveloppes de cathéter à ballonnet sont constituées de structures de fils interconnectés élastiques en tissu, lesdites structures possédant un degré d'étirement et de récupération élevés dans le sens de la circonférence et présentant une modification de dimension réduite dans le sens longitudinal pendant les multiples cycles de mise sous pression à pleine capacité de gonflage et de dégonflage du cathéter à ballonnet. Les enveloppes comprennent des fils longitudinaux positionnés à environ zéro degré par rapport à l'axe du ballonnet, et des fils circonférentiels étirables dans les deux sens, positionnés selon un angle Ø presque droit par rapport audit axe. L'invention concerne un procédé de fabrication des enveloppes de cathéter à ballonnet permettant le positionnement presque perpendiculaire des fils circonférentiels et longitudinaux qui implique le tressage triaxial d'un nombre minimum de fils de tressage élastomères avec de multiples fils axiaux afin d'obtenir un angle de convergence maximum (approchant 90 degrés).
