Abstract:
1. A drug delivery platform for delivering a controlled infusion of a drug to an individual, comprising: a reservoir for receiving the drug therein; a hydrogel engageable with the reservoir, the hydrogel movable between a first configuration and a second configuration wherein the hydrogel exerts a pressure on the reservoir to urge the drug therefrom in response to exposure of the hydrogel to an activation fluid ; a storage structure housing the activation fluid, the activation fluid in the storage structure being fluidicly isolated from the hydrogel; an activation mechanism movable between a first position wherein the activation fluid is fluidicly isolated from the hydrogel and second position wherein the activation fluid is in fluidic communication with the hydrogel; and a flow guide for guiding the activation fluid from the storage structure to the hydrogel with the activation mechanism in the second position, the flow guide having an input; wherein the actuation mechanism includes an initiation conduit having an input and output, the input of the initiation conduit isolated from the activation fluid with the activation mechanism in the first position and the input of the initiation conduit communicating with the activation fluid and the output of the initiation conduit communicating with the input of the flow guide with the activation mechanism in the second position such that the activation fluid flows through the initiation conduit to the input of the flow guide.
