Publication number: 20070199568Abstract: A device and method is provided for delivering an active material or drug in particular form to a targeted region of the nasal passage, such as the turbinates. The device includes a nozzle outlet (28) for the material, supported for example in an outer nozzle (20) which fits the nostril so as not to disrupt non-turbulent flow into the nostril. The particles are released from the outlet (28) into the non-turbulent flow at a similar velocity, in order to follow the airstream. Thus it is possible to predict their likely path, such that preferred release points can be calculated.Type: ApplicationFiled: December 15, 2004Publication date: August 30, 2007Applicant: BESPAK PLC (INCORPORATED IN THE UNITED KINGDOM)Inventors: Colin Diekens, Julia Kimbell, Jeffry Schroeter
