INGESTIBLE DEVICE FOR THE RELEASE OF SUBSTANCES AT DISTINCT LOCATIONS IN THE ALIMENTARY CANAL |
摘要 |
An ingestible device (10) for delivering a substance (12a) to a chosen location in the GI tract of a mammal includes a receiver of electromagnetic radiation for powering an openable part of the device (10) to an opened position for dispensing of the substance (12a). The receiver includes a coiled wire (29) that couples the energy field, the wire (29) having an air or ferrite (36) core. In a further embodiment the invention includes an apparatus for generating the electromagnetic radiation, the apparatus including one or more pairs of field coils (42) supported in a housing. The device (10) optionally includes a latch defined by a heating resistor (20) and a fusible restraint (19). The device (10) may also include a flexible member (51) that may serve the function of activating a transmitter circuit (28) to indicate dispensing of the substance; and means restraining a piston (16) used for expelling the substance.
