IMPLANTABLE DRUG-DELIVERY DEVICES, AND APPARATUS AND METHODS FOR REFILLING THE DEVICES

摘要

In various embodiments, a refill needle (120) is employed in refilling drug-delivery devices. The refill needle (120) encompasses a hollow shaft (212) which extends from a proximal end (200) of the needle to a proximal end (216) terminating in a tip (208). The refill needle includes at least one fluid exit port (220) positioned along the shaft (212), e.g. near the tip (208) and a means (224) suitable for limiting an extent of entry of the refill needle into the entry port (116) of a drug-delivery device (100).
