An access catheter (16) for percutaneously connecting to a sub-cutaneously implanted port comprises a catheter body having a distal end (16), and a proximal end (14). A needle (20) or other access tube is connected to the distal end of the catheter body through a fitting (18), optionally at a right angle relative to the catheter body. A compressible element (30) impregnated with an antiseptic, antibiotic, anesthetic, or other active agent is provided adjacent the distal end of the catheter body, and surrounding the needle. When the needle is percutaneously introduced to the port, the compressible element will be compressed to express the agent onto the skin surface surrounding the penetration site.

Un cathéter d'accès (16) destiné à se connecter par voie percutanée à l'orifice d'un dispositif implanté sous-cutané comprend un corps de cathéter comportant une extrémité distale (16) et une extrémité proximale (14). Une aiguille (20) ou un autre tube d'accès est connecté à l'extrémité distale du corps de cathéter par un raccord (18), facultativement au niveau d'un angle droit par rapport au corps de cathéter. Un élément compressible (30) imprégné d'un antiseptique, d'un antibiotique, d'un anesthésique ou d'un autre agent actif est prévu à côté de l'extrémité distale du corps de cathéter et entoure l'aiguille. Lorsque l'aiguille est introduite par voie percutanée dans l'orifice, l'élément compressible est comprimé pour libérer l'agent sur la surface cutanée entourant le site de pénétration.
