Patent number: 8459257Abstract: A medicament delivery device for administering a medicament to a user includes a medicament reservoir and an entrance port and an exit port each disposed adjacent the reservoir. A gas chamber disposed adjacent the entrance port. The device includes a pressurizing mechanism operable to pressurize said gas chamber to at least a prescribed pressure. A first frangible membrane extends across the entrance port and separates the reservoir from the gas chamber. A second frangible membrane extends across the exit port. When the pressurizing mechanism is attached, at least one of the first and second membranes is responsive to the prescribed pressure in the gas chamber to burst to allow gas to flow through the entrance port and the reservoir and to carry the medicament through the exit port.Type: GrantFiled: May 22, 2009Date of Patent: June 11, 2013Assignee: Becton, Dickinson and CompanyInventors: Robert I. Connelly, Vincent J. Sullivan, Charles D. Shermer, Anjana Bhuta, Ronald J. Pettis

Patent number: 8251958Abstract: A method and device for intradermal delivery of a reconstituted medicament. The device includes a chamber, which is in fluid communication with a microdevice, e.g. microabrader or one or more microneedles. A cartridge containing the medicament may be located within said chamber. At least one burstable membrane retains a medicament within the housing. The method involves the steps of positioning the device at a delivery site on the skin of a patient and intradermally administering the medicament by dispensing a diluent from a diluent source an through inlet port to rupture the membranes, reconstitute the medicament and deliver the reconstituted medicament through the microdevice to the dermal region of the skin.Type: GrantFiled: December 10, 2010Date of Patent: August 28, 2012Assignee: Becton, Dickinson and CompanyInventors: Vincent J. Sullivan, Ronald J. Pettis, John A. Mikszta, John P. Dekker, III, Wendy D. Woodley, Anjana Bhuta Wills, Matthew S. Ferriter, C. Robin Hwang

Patent number: 7896836Abstract: A valved medicament 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 delivery device of this invention may be utilized to deliver a controlled unit dose of a 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: April 12, 2006Date of Patent: March 1, 2011Assignee: Becton, Dickinson and CompanyInventors: Vincent J.

Patent number: 7850663Abstract: A method and device for intradermal delivery of a reconstituted powdered medicament. The device includes a chamber, which is in fluid communication with a microdevice, e.g. microabrader or one or more microneedles. A cartridge containing the powdered medicament may be located within said chamber. At least one burstable membrane retains a powdered medicament within the housing. The method involves the steps of positioning the device at a delivery site on the skin of a patient and intradermally administering the medicament by dispensing a diluent from a diluent source an through inlet port to rupture the membranes, reconstitute the powdered medicament and deliver the reconstituted medicament through the microdevice to the dermal region of the skin.Type: GrantFiled: June 1, 2004Date of Patent: December 14, 2010Assignee: Becton, Dickinson and CompanyInventors: Vincent J.
