The pictures to the left and in the middle illustrate the concept of the refill-exchange procedure. A correct execution requires the full penetration of the special vented refill needle into the self-sealing septum of the PDS implant. This can only be achieved if the entry point of the needle is centralized within the septum surface and the needle is perpendicularly aligned with the implant. The picture to the right shows a simulator screenshot and illustrates the use of abstract guidance elements to help the user understand the geometric challenges of the procedure
