Patent number: 7051734Abstract: A medicament respiratory delivery device including a housing having a chamber including coaxially aligned inlet and outlet, a medicament cartridge located within the chamber having a passage therethrough and membranes sealing the passage having a burst pressure of less than 10 atmospheres, a manually actuatable fluid delivery device having an outlet in fluid communication with the chamber and a manually actuated valve located between the outlet of the fluid delivery device and the chamber inlet for delivery of fluid under pressure to the valve. The medicament respiratory delivery device of this invention may be utilized to deliver a controlled unit dose of an aerosolizable medicament on demand by first pressurizing a pressure chamber in the pressure delivery device upstream of the valve, then opening the valve to open the membranes and express the medicament through the chamber outlet.Type: GrantFiled: October 14, 2003Date of Patent: May 30, 2006Assignee: Becton Dickinson and CompanyInventors: Robert A.

Patent number: 6561186Abstract: An inhalation-activated inhalator having a primary inhalation passage and a secondary inhalation passage disposed in communication with the primary inhalation passage and a source of medicament. The primary inhalation passage has airflow inhibiting mechanism connected to a blocking plate positioned to selectively block fluid flow in the secondary inhalation passage. As the user's inhalation reaches a defined rate, the flow inhibiting mechanism restricts flow through the primary inhalation passage and moves the blocking plate to enable airflow through the secondary passage. Thus, as the user achieves a desired inhalation rate, the medicament is provided through the secondary inhalation passage, thereby optimizing the delivery of medicament to the lungs.Type: GrantFiled: November 27, 2001Date of Patent: May 13, 2003Assignee: Innovative DevicesInventors: Robert A. Casper, Frank A. Leith, David L. Gardner, John M. Snow, Zachary W. Lyon, David S. Farrar

Patent number: 5415162Abstract: A breath-actuated dry powder medicament inhalator device having a housing and a conduit mounted within the housing defining an air passageway therethrough having an aperture in the sidewall thereof. A blister-type strip of sealed containers arranged in a matrix of rows and columns wherein the columns extend generally diagonally to the longitudinal axis of the strip is secured in a two-piece cage adapted for being rotatably mounted around the conduit of the inhalator device. Advancement means are provided for rotatably moving the two-piece cage and blister strip contained thereby in a generally helical pathway relative to the conduit so as to successively advance each of the sealed containers of the blister strip into registration with the conduit aperture.Type: GrantFiled: January 18, 1994Date of Patent: May 16, 1995Assignee: Glaxo Inc.Inventors: Robert A.
