Title
(EN) SOFT FLEXIBLE CATHETER TIP FOR USE IN ANGIOGRAPHY
(FR) POINTE SOUPLE DE CATHETER S'UTILISANT EN ANGIOGRAPHIE
Abstract
(EN)
A plurality of regions of a first transverse rigidity are formed in the flexible tip portion (12) of a catheter having a second transverse rigidity along its length which is greater than the first transverse rigidity. The regions of the lesser first transverse rigidity are formed by areas of the catheter tip (12) having an average transverse cross-sectional area less than a transverse cross-sectional area of the remainder of the catheter apparatus. The plurality of first transverse rigidity regions are formed by a respective plurality of circumferential cutout regions (20-30) in the catheter tip (12).
(FR)
Une pluralité de régions présentant une première rigidité transversale se trouve dans la partie souple formant la pointe (12) du cathéter, dont la longueur possède une deuxième rigidité transversale supérieure à la première. Les régions présentant la première rigidité transversale inférieure sont constituées par des zones de la pointe (12) du cathéter, dont la section transversale moyenne est inférieure à celle du reste du cathéter. La pluralité de régions présentant la première rigidité transversale est constituée par une pluralité respective de régions concentriques (20-30) découpées dans la pointe du cathéter (12).
