Abstract
Devices and methods are provided for drug delivery. The device may include a housing configured for intraluminal deployment into a human or animal subject and first and second reservoirs within the housing, each reservoir having an actuation end, an opposed release end, and a plug moveable from the actuation end toward the release end. First and second drug formulations may be contained in the first and second reservoirs, respectively. The device may also include one or more actuation systems configured to drive the first and second plugs so as to drive the first and second drug formulations from the first and second reservoirs. The housing may include a porous membrane sidewall in fluid communication with the release ends of the first and second reservoirs, the porous membrane sidewall being configured to distribute the first and second drug formulations driven from the first and second reservoirs.
