Delivery of Functionalized Particles

摘要

A device includes a capsule sized to pass through a lumen of a gastrointestinal tract, a plurality of functionalized particles disposed within the capsule, one or more tissue penetrating members configured to puncture a wall of the lumen of the intestinal tract; and an actuator having a first configuration and a second configuration. The actuator is configured to retain the plurality of functionalized particles within the capsule in the first configuration. The actuator is further configured to advance the plurality of functionalized particles from the capsule into a wall of the lumen of the gastrointestinal tract via the one or more tissue penetrating members by the actuator transitioning from the first configuration to the second configuration. Systems including the device and methods of delivering functionalized particles to the body are also provided.
