Patent number: 7763014Abstract: An ingestible device for delivering a substance 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 to an opened position for dispensing of the substance. The receiver includes a coiled wire that couples the energy field, the wire having an air or ferrite 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 supported in a housing. The device optionally includes a latch defined by a heating resistor and a fusible restraint. The device may also include a flexible member that may serve one or both the functions of activating a transmitter circuit to indicate dispensing of the substance; and restraining of a piston used for expelling the substance.Type: GrantFiled: July 30, 2007Date of Patent: July 27, 2010Assignee: Phaeton Research Ltd.Inventors: Peter J. Houzego, Peter N. Morgan, Peter H. Hirst, Duncan J. Westland, Ian R. Wilding

Publication number: 20040220537Abstract: A unit container for a treatment fluid comprises a sealed enclosure of which one wall section thereof is formed with at least one opening. The enclosure is pressuriseable to discharge its contents thorough the opening or openings, which is or are of sufficient diameter to enable the generation of a jet and/or discrete droplets of treatment fluid discharged therefrom. The one wall section is typically a flat section of the enclosure wall, and the enclosure is typically a blister pack, with the wall section at a planar base of the blister. However the one wall section may be dome-shaped and formed with at least one opening in the top region of the dome. Containers of the invention may be provided in packages, for example in strip form or in planar arrays. Dispensing devices are described for discharging their content in treatment.Type: ApplicationFiled: December 19, 2003Publication date: November 4, 2004Applicant: Pharmacia AktiebolagInventors: Jonathan K. Embleton, Stephen P. Jones, Richard J. Malcolmsen, Luigi G. Martini, Peter J. Houzego, Sarah A. Rocca, Howard N. Stevens

Patent number: 5487378Abstract: An inhaler for dispensing droplets of liquid medicament to a patient comprising a body having a mouthpiece or nasal adaptor and a reservoir of liquid medicament in communication with an aerosol generator. The aerosol generator includes a chamber for the liquid medicament and a nozzle arrangement having a plurality of orifices. Means are provided for cyclically pressurizing the liquid medicament in the chamber such that liquid from the chamber is periodically expelled through the orifices of the nozzle arrangement as atomizer droplets of liquid medicament. Dosage control means are also provided for deactivating the aerosol generator after a predetermined time or after a predetermined volume of liquid medicament has been expelled from the chamber.Type: GrantFiled: October 4, 1993Date of Patent: January 30, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Paul A. Robertson, Peter J. Houzego, Borge R. Jensen, Murray A. Creeke, Neil Emerton, Peter D. Hodson, Eric A. Baum
