Abstract
Drug delivery devices and methods are provided. The device included two or more housing units connected together end-to-end in a fixed, linear orientation, the exterior surfaces of the connected housing units defining a sidewall of the device; discrete drug dose units disposed within the housing units; degradable timing members connected to the housing units and separating the discrete dose units from one another; first and second end pieces defining opposed ends of the device such that the discrete dose units are located between the first and second end pieces within each of the housing units, wherein the device is configured to release in vivo a first of the discrete dose units following rupture of the first or second end piece, and subsequently to release in vivo a second of the discrete dose units following rupture of the degradable timing member separating the first discrete dose unit from the second discrete dose unit.
