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 may extend from a proximal end (200) of the needle to a proximal end (216) of a terminating 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).
