Patent attributes
A device is provided for the administration of a compound in a body. The device includes a capsule having a reservoir therein for receiving the compound therein and a delivery instrument for positioning the capsule within the body. The delivery instrument includes a barrel having an interior adapted to receive the capsule therein and a dispersal element interacting with the barrel to selectively expel the capsule therefrom and into the body. A diffusion regulator communicates with the reservoir and controls the diffusion of the compound from the reservoir into the body. A retention structure projects from capsule and is configured to retain the capsule at a desired location within the body. Multiple devices may be used in conjunction to provide a multiplexed point source to administer multiple compounds simultaneously in vivo.
