The subject catheters are further characterized in that they include a multiport manifold (18) at their proximal ends, where at least two of the ports (11a, 11c) of the multiport manifold may comprise luer valves (15a, 15c). Also provided are systems for use in flushing a vascular site with fluid, usually at least two different fluids, where the subject systems are made up of two multilumen catheters according to the subject invention, where one of the catheters is inserted inside of the other. In addition, kits comprising various components of the subject systems, e.g., at least two different multilumen catheters, are provided. The subject multilumen catheters, systems and kits find use in a variety of different applications in which it is desired to flush a vascular site with at least one and preferably two different fluids, where particular applications of interest include the treatment of vascular lesions.

Cette invention se rapporte à des cathéters multilumières, qui comprennent une extrémité proximale et une extrémité distale séparées par un tube multilumière non coaxial. Ces cathéters se caractérisent en outre en ce qu'ils comportent à leurs extrémités proximales un collecteur multivoie, au moins deux des voies du collecteur multivoie pouvant comprendre des valves Luer. Cette invention concerne également des systèmes servant au rinçage d'un site vasculaire à l'aide d'un fluide, habituellement à l'aide d'au moins deux fluides différents, ces systèmes étant constitués d'au moins deux cathéters multilumières faisant l'objet de cette invention, l'un de ces cathéters étant inséré dans l'autre. Cette invention concerne également des kits comprenant divers composants de ces systèmes, par exemple au moins deux cathéters multilumières différents. Ces cathéters multilumières, ces systèmes et ces kits trouvent une utilisation dans diverses applications différentes, où on souhaite rincer un site vasculaire à l'aide d'au moins un, de préférence à l'aide de deux fluides différents, le traitement des lésions vasculaires constituant l'une de ces applications particulières.
