Publication number: 20220032028Abstract: A device can include a capsule containing an array of microneedles and a mechanical actuator. The device can be in an ingestible form for delivery to a duodenum or other target location within a subject and can release the mechanical actuator from constraint by the capsule in response to stimuli or conditions in or en route to the duodenum or other target location. The mechanical actuator upon release from constraint by the capsule can expand outwardly (e.g., responsive to a bias provided by a flexibly resilient material of the mechanical actuator) in a direction away from a central longitudinal axis of the mechanical actuator and drive the array of microneedles into penetrating engagement with a lining of the duodenum or other target location. The penetrating engagement can facilitate delivery of a biotherapeutic agent or other payload via the microneedles.Type: ApplicationFiled: July 21, 2021Publication date: February 3, 2022Applicant: Verily Life Sciences LLCInventors: Eric Bennett, Kimberly Kam, Martin Sheridan, Annapurna Karicherla, Kassidy MacPhail
