US 2025/0050081 A1 · DEVICES, ASSEMBLIES, AND METHODS FOR DELIVERING A FLUID PREPARATION INTO A GASTROINTESTINAL TRACT

Abstract

A delivery assembly for an ingestible device to deliver a fluid preparation into a GI lumen wall or surrounding tissue of a subject includes a housing, a piston, a needle, a conduit, and a valve member. The housing defines a piston chamber. The piston is movably disposed in the piston chamber. The needle is coupled to, or integrally formed with, the piston. The conduit is structured to direct the fluid preparation from a fluid source to the needle. The valve member has a first state and a second state. In the first state, the valve member substantially impedes a flow of the fluid preparation from the conduit to the needle. In the second state, the valve member is structured to allow the fluid preparation to flow through the conduit to the needle.
