Abstract: The present disclosure describes various aspects of various devices, and methods of making and using the devices, for measuring bioimpedance of tissues within a patient's body, such as GI tract tissue. The devices entail using various implementations of capsules or other housings that allow for ingestion or other insertion into a body of the device, equipped with microfabricated sensors and embedded circuitry enabling wireless communication. Among other benefits, this approach addresses a gap in conventional GI tract monitoring devices and methods to non-invasively access the small intestine and directly measure the inflammatory state of intestinal tissue, including ischemia, edema, and mucosal abnormalities.

Abstract: This disclosure sets forth various systems and methods for deploying anchored medical devices within a human or animal. The medical devices may deliver payloads, such as various sensors, electrodes, transmitters, cameras, electrical or other interventional devices, drugs or therapeutics. The devices may have one or more anchors, which attach the device to an anatomy of interest. This allows for methods and processes to be performed over periods of time, such as extended delivery of a therapy or real time sensing of characteristics inside a body, which the device remains within a given location.

Abstract: An apparatus for monitoring a bioprocess parameter. The apparatus includes: a housing; a bioprocess sensor attached to an outer surface of the housing; a power supply contained within the housing; and an electronics module contained within the housing and in communication with the power supply and the sensor, where the electronics module includes a wireless communication unit.

Abstract: A microneedle system includes an ingestible structure and one or more microneedle units secured to a surface of the structure. Each microneedle unit has a plurality of barb members extending from the outer surface of a microneedle. The microneedle unit is secured to the structure by a displacement member, which displaces the microneedle unit when in a released state. The displacement member may be held in a compressed state by a dissolvable coating.
