INGESTIBLE DEVICE WITH DELIVERY MEMBER DETACHMENT

An ingestible device is disclosed suitable for swallowing into a lumen of a gastrointestinal tract of a patient, the lumen having a lumen wall. The ingestible device (100, 200) comprises: a capsule (110, 120), a delivery member (130) being shaped to penetrate tissue of a lumen wall and having a tissue penetrating end and a trailing end, the delivery member (130) comprising a therapeutic payload, a ram (150) attached relative to the delivery member (130) at the trailing end; and an actuator (140) coupled to the ram (150) and having a first configuration and a second configuration, the delivery member (130) being retained by the ram (150) within the capsule (110, 120) when the actuator (140) is in the first configuration, wherein the delivery member (130) is configured to be advanced from the capsule (110, 120) and into the lumen wall by movement of the actuator (140) from the first configuration to the second configuration such that the delivery member (130) moves along a predefined trajectory. The ram (150) is configured for being tilted relative to the predefined trajectory upon the actuator (140) moving into the second configuration to detach at least a portion of the delivery member (130) from the ram (150) such that the detached portion of the delivery member (130) remains within the lumen wall to release therapeutic payload.

MEDICAL FLUID TRANSFER AND INJECTION APPARATUS AND METHOD

Drug delivery system, injection device, transfer apparatus, vial holder and method of administering and transferring are disclosed which provide for passive warming of chilled injectable transferred through the transfer apparatus and into the injection device. The injection device may include a skin-facing surface including a skin boundary displacement extension or structure around a needle injection site to create a high pressure zone in the tissue. Radio frequency tracking and monitoring features for tracking patient compliance also may be provided.
