1. A device for the administration of a compound in a body, comprising:

  • a capsule having an inner surface defining a reservoir for receiving the compound therein;

    a diffusion regulator having an input communicating with the reservoir and an output receivable in the body, the diffusion regulator configured to control the diffusion of the compound from the reservoir into the body with the output of the diffusion regulator received in the body; and

    a resilient retention structure projecting from the capsule, the retention structure having a variable configuration;

    wherein the diffusion regulator includes a needle having a first end communicating with the reservoir and a second end receivable in the body and defining the output of the diffusion regulator.
