The bent needle a nurse pushes through the skin into an implanted port. Its tip is shaped so it slices rather than punches the port's rubber seal, which lets the seal close again after thousands of uses.
The FDA lists these as product code PTI (non-coring (Huber) needle; 21 CFR 880.5570, class II). Examples include Bard Access Systems' PowerLoc Max power-injectable infusion set and SafeStep Huber needle set (K241353, 27 November 2024) and Intera Oncology's non-coring refill and bolus needles for its implanted hepatic artery pump (K211121, 14 October 2021). A standard needle would cut a core out of the port's silicone septum, which over time would make it leak; the deflected tip of a Huber needle avoids that. Safety designs shield the tip on removal to protect staff from needlestick injury.
A needle with a deflected, side-opening bevel parts the septum fibres instead of cutting a plug, and is usually bent at right angles so it lies flat on the skin under a dressing.
