This invention has a catheter (10) with a distal end which is to be positioned through potentially contaminated tissue within a patient to a desired site, and a proximal end. The catheter has at least one fluid lumen (18) extending between the distal end and the proximal end. The fluid lumen (18) provides fluid communication between the desired site and the proximal end. A removable protective barrier (22) is positioned within the fluid lumen at its distal end. The protective barrier (22) is made from a bio-compatible material and selectively occludes the distal end of the fluid lumen so that entry of the contaminated tissue, prior to the distal end of the catheter reaching the desired site, is prevented.
Sonde (10) dotée d'une extrémité distale à acheminer dans un site désiré chez un patient, à travers des tissus potentiellement contaminés, et d'une extrémité proximale. Ladite sonde possède au moins un passage (18) de fluide s'étendant entre l'extrémité distale et l'extrémité proximale. Le passage (18) de fluide établit une communication fluidique entre le site désiré et l'extrémité proximale. Une barrière protectrice amovible (22) est placée à l'intérieur du passage de fluide, à son extrémité distale. Ladite barrière protectrice (22) est constituée d'un matériau biocompatible et obstrue sélectivement l'extrémité distale du passage de fluide si bien qu'elle empêche l'entrée de tissus contaminés avant que l'extrémité distale de la sonde n'atteigne le site désiré.
