Title (EN) URINARY CATHETER
(FR) CATHÉTER URINAIRE
Abstract:
(EN) A medical device is disclosed, comprising a substrate, having on its surface, on at least a part thereof, a hydrophilic surface layer providing low-friction surface character of the medical device when wetted by a wetting fluid. The substrate is made of a polymer blend comprising a polyolefin and a composition having molecules with active hydrogen(s), such as polyamide or polyurethane. The hydrophilic surface layer is preferably adhered to the substrate by a polyurea network, whereby said polyurea network forms a covalent bond to said active hydrogen(s) in the substrate. The new substrate material is environmentally acceptable and cost effective, has adequate mechanical and chemical properties and enables the hydrophilic coating to be adequately adhered.
(FR) La présente invention concerne un appareil médical se composant d’un substrat qui comporte sur au moins une partie de sa surface, une couche de surface hydrophilique donnant un caractère à faible friction à la surface de l'appareil lorsqu’il est mouillé par un fluide humectant. Le substrat est constitué d’un mélange de polymères comprenant une polyoléfine et un composé comportant des molécules contenant un ou plusieurs hydrogènes actifs tels que du polyamide ou du polyuréthane. La couche de surface hydrophilique est de préférence jointe au substrat par un réseau de polyuréa de manière à ce que ledit réseau forme un liant covalent auxdits hydrogènes actifs du substrat. Le matiériau du nouveau substrat est acceptée par l’environnement et économique et présente des propriétés mécaniques et chimiques adéquates et permet au revêtement hydrophilique d’adhérer de manière satisfaisante.
