Microfluidic device for multiplexed point source administration of compounds

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;
• a resilient retention structure projecting from the capsule, the retention structure having a variable configuration;
• and
• a delivery instrument including:
• an elongated tube having an inner surface defining a passage for receiving the capsule therein, and first and second ends;
• and
• a push rod slideably received in the first end of the elongated tube, the push rod engageable with the capsule for urging the capsule from the passage of the elongated tube through the second end thereof.
