Ambix Intrastick® special cannulas with spoon bevel Ambix Intrastick® specialty needles were specifically developed to enable precise puncture of implantable port membranes. The patented spoon-shaped tip ensures virtually punch-free insertion. The integrated bellows allows for individual adjustment of the insertion depth while simultaneously relieving strain. Thanks to the integrated adhesive, the port cannula is held securely in place. A self-sealing safety valve provides additional protection. The tubing is 20 cm long.
