Abstract

L'invention se rapporte à un système d'orientation pour une pointe de cathéter. Ce système comprend des fils métalliques (24a, b) qui s'étendent à travers une paroi (50) de cathéter et qui sont utilisés pour tirer une partie distale de la pointe du cathéter, ce qui produit une courbure prédéterminée et régulée au niveau de cette pointe. Des éléments d'ancrage (22) situés à proximité de la pointe relient l'extrémité distale aux fils (24a, b). Le système d'orientation comprend également des éléments de commande situés au niveau d'une partie proximale du cathéter, et qui sont utilisés pour commander le tirage des fils (24a, b). Des éléments (14) facilitant l'orientation, également compris dans le système, facilitent la courbure de la paroi (50) du cathéter.
