Title (EN) CATHETER WITH CHANGEABLE NUMBER OF LUMENS
(FR) CATHETER AVEC POSSIBILITE DE MODIFIER LE NOMBRE DE PASSAGES
Abstract:
(EN) A catheter assembly (10) is provided. An attachment structure (22) has a proximal end portion (24) of an outer cannula (28) attached to it. A needle (18) is insertable through the outer cannula (28) and the attachment structure (22). An inner cannula (52) is attached to an inner cannula attachment region of the attachment structure (22). The inner cannula (52) is insertable axially through the attachment structure (22). The attachment structure (22) can comprise two hubs (38) one for the outer cannula (28) and the other for the inner cannula (52), the two hubs (38) being attachable to one another to form the overall attachment structure (22). A valve structure (70) is associated with the attachment structure (22), suitably with the outer cannula hub (22). The valve structure (70) normally closes communication between an access passage in the attachment structure (22) and the outer cannula lumen (34).
(FR) L'invention concerne un cathéter (10). Une structure de fixation (22) possède une portion extrême proximale (24) d'une canule externe (28) qui y est fixée. Une aiguille (18) peut être introduite à travers la canule externe (28) et la structure de fixation (22). Une canule interne (52) est fixée à une région de fixation d'une canule interne de la structure de fixation (22). La canule interne (52) peut être introduite axialement à travers la structure de fixation (22). La structure de fixation (22) peut avoir deux moyeux (38), l'un pour la canule externe (28) et l'autre pour la canule interne (52), les deux moyeux (38) pouvant s'attacher l'un à l'autre pour former la structure de fixation complète (22). Une structure à clapet (70) est associée à la structure de fixation (22), de manière appropriée avec le moyeu (22) de la canule externe. La structure à clapet (70) ferme normalement la communication entre un passage d'accès dans la structure de fixation (22) et le passage (34) de la canule externe.
