Patent number: 8261740Abstract: An inhaler comprising: a body; at least one cover element that is movable between a closed position and an open position; individual reservoirs formed on a reservoir substrate; movable support means that receive said reservoir substrate and that are displaceable between a non-dispensing position and a dispensing position; and an indicator device for indicating doses that have been dispensed or that remain to be dispensed, said indicator device comprising: a rotary indicator element that supports indicator means, such as numbers, colors, and/or symbols; and an actuator that co-operates with said movable support means so as to cause said rotary indicator element to turn when said movable support means return from the dispensing position to the non-dispensing position.Type: GrantFiled: July 17, 2007Date of Patent: September 11, 2012Assignee: Valois SASInventors: Andrew Gordon Pocock, Stuart Brian William Kay, Paul Greenhalgh, Wayne O'Hara, Xavier Donnette

Publication number: 20120089083Abstract: Apparatus, e.g. a syringe, for dispensing foam includes means for ensuring that only foam of adequate quality is dispensed. In use, the syringe may be filled from a pressurised canister which generates foam e.g. for therapeutic use in treating varicose veins. An initial quantity of foam dispensed from the canister may be of inadequate quality in which case it should not be used: the syringe includes means to ensure that this initial quantity of foam is diverted to a waste port or to an internal waste chamber e.g. located in the syringe plunger. Foam dispensed after the initial quantity of poor quality foam is stored in the main barrel of the syringe ready for administration to a patient in need of treatment.Type: ApplicationFiled: September 14, 2011Publication date: April 12, 2012Applicant: BTG International LimitedInventors: Stuart Brian William Kay, Christopher John Hurlstone, Julian Richard Dixon, Andrew Gordon Pocock, Brendan Hogan

Patent number: 8122917Abstract: A foam transfer device is described, for use with aerosol canister apparatus for producing a sclerosant foam for the treatment of, inter alia, varicose veins. The device enables diversion of an initial quantity of below-specification foam from the canister to waste, e.g. to an integral waste chamber, before dispensing a further quantity of foam for use in treatment. The switching of the flow from the waste chamber to a different outlet for use is accomplished without interrupting the flow from the aerosol canister since this would cause the foam to drop below specification again. The waste chamber may be transparent so that the foam entering it can be observed and a decision made by a user when to stop diverting foam to waste. Alternatively, the foam may be diverted automatically e.g. when a set time has elapsed or a set volume of foam dispensed. The foam for use is normally dispensed into a syringe for subsequent injection into a varicose vein of a patient.Type: GrantFiled: September 9, 2010Date of Patent: February 28, 2012Assignee: BTG International LimitedInventors: Anthony David Harman, David Dakin Iowerth Wright, Jam Wilem Marinus Mijers, Stuart Brian William Kay, Christopher John Hurlstone, Julina Richard Dixon, Andrew Gordon Pocock, Brendan Hogan

Patent number: 8047203Abstract: A unit dose dry powder inhaler has a dispersion chamber, optionally including one or more beads. A blister is supported adjacent to the dispersion chamber. A mouthpiece cover is removable from a mouthpiece, with movement of the mouthpiece cover causing the blister to open. An air flow path extends past or under the blister and into the dispersion chamber. As a result, the blister remains sealed until the inhaler is ready for use. The blister is then automatically opened when the mouthpiece cover is removed from the mouthpiece. Pharmaceutical dry powder is released from the blister and entrained in air flow through the inhaler, when the user inhales on the mouthpiece. The powder is dispersed in air within the dispersion chamber.Type: GrantFiled: July 18, 2005Date of Patent: November 1, 2011Assignee: Quadrant Technologies LimitedInventors: Matthew E. Young, Stuart Brian William Kay, Neil R Harrison

Publication number: 20110259329Abstract: A breath-actuated delivery device includes a mouthpiece through which a subject in use exhales, an air channel which is in fluid communication with the mouthpiece, and a flexible diaphragm which is disposed in the air channel. The diaphragm provides for at least a restricted air flow through the air channel until a predeterminable actuation pressure is developed in the mouthpiece, and, on generation of the predeterminable actuation pressure in the mouthpiece, provides for an air flow through the air channel.Type: ApplicationFiled: August 30, 2010Publication date: October 27, 2011Applicant: OptiNose ASInventors: Per Gisle Djupesland, Martin Joseph Murphy, Stuart Brian William Kay, Andrew Gordon Pocock

Patent number: 7814943Abstract: Apparatus for dispensing foam for the treatment of, inter alia, varicose veins. The apparatus includes a source of foam and a dispensing device which has an inlet in communication with the source of foam, a usable foam outlet, and a waste bleed outlet. The waste bleed outlet communicates with the inlet and with the useable foam outlet, and has a higher resistance to flow of foam than that of the usable foam outlet. The useable foam outlet may be blocked off such that foam may flow through the high resistance waste bleed outlet, and the usable foam outlet may be opened such that foam may flow through the usable foam outlet.Type: GrantFiled: September 9, 2004Date of Patent: October 19, 2010Assignee: BTG International LimitedInventors: Anthony David Harman, David Dakin Iowerth Wright, Jam Willem Marinus Mijers, Stuart Brian William Kay, Christopher John Hurlstone, Julian Richard Dixon, Andrew Gordon Pocock, Brendan Hogan

Publication number: 20090235930Abstract: A unit dose dry powder inhaler has a dose unit within an inhaler housing. As the dose unit is pushed into the inhaler housing, a container on the dose unit is opened, releasing a pharmaceutical powder into the housing. The user inhales on a mouthpiece, drawing the powder and air into a dispersion chamber. The powder disperses in air, and the powder/air mixture is inhaled. The inhaler is inexpensive, compact, and simple to use.Type: ApplicationFiled: June 2, 2009Publication date: September 24, 2009Inventors: Matthew E.

Publication number: 20090235931Abstract: A unit dose dry powder inhaler includes a chamber housing containing a powder dispersion chamber. A chamber tube extends from the dispersion chamber into the mouthpiece. A cover or cup is rotatably attached to the chamber housing. A dose of a dry powder is contained at a powder location in the chamber housing. An air passageway leading from the powder location to the dispersion chamber is closed off by the cover. When the cover is rotated to an open position, the air passageway is opened. The user inhales on the mouthpiece drawing air through the powder location, the air passageway, the dispersion chamber and the chamber tube, through the mouthpiece and into the users lungs. The unit dose of dry powder is stored directly in, or is part of, the inhaler.Type: ApplicationFiled: June 3, 2009Publication date: September 24, 2009Inventors: Matthew E.
