1. A medicament delivery system comprising:
- a reservoir for storing a medicament, a channel for carrying a volume of the medicament from the reservoir into a passage within a perforator, and an actuator coupled to the perforator and capable of applying a decelerating force thereto for causing the inertia of the volume to eject the medicament from the hollow perforator.

Abstract
The systems and methods described herein include, inter alia, drug delivery devices that can provide doses of medicaments over a defined region of skin. Such systems and methods described herein may employ a hollow perforator that can receive a volume of drug and an actuator that can drive the perforator through a stroke cycle that accelerates the perforator and the volume of drug distally and then decelerates the perforator so that the volume of fluid is ejected out of the perforator.
