摘要：
Devices and methods are provided for drug delivery. The device may include a housing configured for intralumenal deployment into a human or animal subject and a reservoir contained within the housing and having an actuation end and a release end. The release end may include at least one outlet. A first drug formulation and a second drug formulation may be disposed within the reservoir and adjacent to each other and immiscible, or separated from each other by a first barrier. The device may also include a plug within the reservoir at the actuation end, the plug being movable toward the release end to drive the first and second drug formulations out of the reservoir. The device may also include an actuation system operably connected to the actuation end of the reservoir and configured to drive the plug toward the release end and release the drug formulations from the reservoir.
