Abstract: front page image
(EN)Described herein are devices and methods for guide catheters having one or more regions of increased flexibility. A flexibility region comprises one tubular segment of the guide catheter with a non-linear longitudinal seam between two non-concentric layers of material having different durometers. A non-linear seam, such as a zig-zag or sinusoidal configuration, permits controlled compression of lower durometer material between portions of higher durometer material.
(FR)L’invention concerne des dispositifs et des procédés pour des cathéters de guidage ayant une ou plusieurs régions de flexibilité accrue. Une région de flexibilité comporte un segment tubulaire du cathéter de guidage avec une couture longitudinale non linéaire entre deux couches non concentriques de matériau ayant différentes duretés indiquées par duromètre. Une couture non linéaire, telle qu’une configuration en zigzag ou sinusoïdale, permet une compression régulée de matériau de dureté indiquée par duromètre inférieure entre des parties de matériau de dureté indiquée par duromètre supérieure.
