An access port (10) comprises a base (12) and a flexible conduit (14). The port is subcutaneously implanted and the conduit is attached directly or indirectly to a blood vessel or other body lumen or cavity. An actuator mechanism (24) is provided with a linkage which opens a valve in the port in response to percutaneous insertion of a needle into the access port. In particular, insertion of the needle opens the clamping mechanism to permit flow through the conduit between the blood vessel and the needle.

L'invention concerne une chambre à injection implantable comprenant une base et un conduit flexible. Cette chambre est implanté sous la peau et son conduit est rattaché directement ou indirectement à un vaisseau sanguin ou à une lumière ou une cavité corporelle . Un mécanisme d'actionnement pourvu d'une liaison permet d'ouvrir une soupape du dispositif suite à l'insertion d'une aiguille dans le dispositif d'accès par voie percutanée. L'insertion de cette aiguille permet en particulier d'ouvrir le mécanisme de fixation pour permettre un écoulement de fluide à travers le conduit situé entre le vaisseau sanguin et ladite aiguille.
