摘要： A device for providing access to an implantable fluid transfer port, comprises a needle extending to a distal end insertable into body to enter a reservoir of a port implanted therein and an actuation member extending through a lumen of the needle from an actuator which remains external to a living body accessible to a user thereof in combination with an obturator coupled to a distal end of the actuation member, an outer diameter of the obturator substantially matching an inner diameter of the lumen of the needle so that, when retracted into the lumen, the obturator seals a distal opening thereof and an anchoring mechanism coupled to the actuation member proximally of the obturator, the anchoring mechanism being moved to an expanded state in which an outer diameter of the anchoring mechanism exceeds an outer diameter of the needle when moved out of the lumen of the needle.
