Abstract:
A breath actuated dry powder medicament inhaler (10) has a primary air passageway (14) therethrough defining a venturi (14c) in the medial portion thereof. A second air passageway (16) is provided which contains a compound deaggregating swirl chamber (16c) and is fluidly connected to the venturi (14c). A dry powder storage chamber (18) and cooperatively associated metering plate (18b) act to introduce a predetermined amount of compound into the swirl chamber upon actuation of the metering plate. The primary air passageway (14) is configured within the inhalator apparatus so as to create an optimized air flow trajectory through the mouth of the user to minimize dry powder compound impingement upon the outside radius of the throat.

Abstract:
A medical capsule device (10) for releasing and/or collecting a substance at a defined location in the gastrointestinal tract. The device has a capsule body (12) defining one or more apertures in the circumferential wall thereof and a sleeve valve rotatably positioned therein having one or more corresponding apertures in the circumferential wall thereof. The sleeve valve comprises a coil and electrically connected heatable resistor which are operatively associated with an actuator member (16J, 16I) formed of a shape memory alloy responsive to heat and which will move from a non-heated first shape to a heated second shape. Actuator stop means (20) are provided in the capsule body for being engaged by the actuator member during movement from the non-heated first shape to the heated second shape so that the actuator member movement will serve to rotate the sleeve valve to either an open or closed position.
