Patent number: 7625548Abstract: Liquid nanoscale particle precursor materials for generating nanoscale particles include at least one high volatility carrier and a second component. A nanoscale particle generating device generates nanoscale particles by passing a liquid nanoscale particle precursor material through a flow passage heated to convert the carrier into a vapor and the second component into nanoscale particles. The nanoscale particles preferably consist essentially of the second component and can consist essentially of dry, solid particles. The particle generator can be incorporated in a hand held inhaler, and can be delivered to a targeted portion of the lung using the inhaler. Composite controlled release particles of micron or nanoscale size can be produced by flowing a solution of medicament, control release agent and carrier liquid through a capillary heater.Type: GrantFiled: May 5, 2008Date of Patent: December 1, 2009Assignee: Philip Morris USA Inc.Inventors: Tung T.

Patent number: 7458373Abstract: An aerosol generator such as a hand-held inhaler and method of delivering aerosol to a user inhaling on an outlet of a mouthpiece when a pressure drop is detected within the mouthpiece. A medicated fluid passing through a capillary passage is heated sufficiently to vaporize the fluid and form the aerosol by condensation of the vaporized fluid as it admixes with air. Air is supplied to the mouthpiece through an air passage which is initially closed during detection of the pressure drop. A metering chamber allows consistent delivery of precise doses of fluid to the capillary passage. The pressure drop is detected before air is supplied to the mouthpiece with the result that the aerosol can be quickly delivered to the user as the user begins to inhale on the mouthpiece. The quick delivery of aerosol provides more efficient use of the user's lung capacity.Type: GrantFiled: January 14, 2003Date of Patent: December 2, 2008Assignee: Philip Morris USA Inc.Inventors: Walter A. Nichols, Donald L. Brookman, Gary E. Grollimund, Ulysses Smith
