Injection of a therapeutic formulation into a wall of the gastrointestinal tract

Abstract

A device includes an inflatable balloon, a reservoir disposed within the inflatable balloon, a needle compartment attached to the balloon and to the reservoir, an injection needle disposed within the needle compartment, and an inflation mechanism. The reservoir contains a therapeutic preparation. The inflation mechanism is structured to inflate the balloon, and upon inflation, the injection needle is structured to enter the reservoir. A method includes making an autoinjector available to a subject with instructions to ingest the autoinjector. The autoinjector is structured to inject a therapeutic preparation into a wall of a gastrointestinal tract of the subject responsive to ingestion of the autoinjector. The autoinjector includes an injection needle disposed in a needle compartment attached to a reservoir. The injection needle is initially separated from the reservoir, and is structured to enter the reservoir for delivery of the fluid therapeutic preparation through the needle into the wall.
