摘要：
Embodiments of the present invention provide a vent arrangement integrated with a refill port disposed on the outer shell of an implantable drug-delivery device. The vent arrangement may utilize a tiered structure with two septums in a space-efficient configuration that facilitates both venting of pressure and refill of the drug reservoir.
