Publication number: 20230048181Abstract: Liquid drug cartridges and an associated inhaler are used to deliver one more separate doses of an aerosolized liquid drug. A cartridge includes a container for storing the liquid drug, an end cap having an ejection opening, a filter element, and a piston that is repositionable relative to the container to selectively eject a volume of liquid drug from the ejection opening. The filter element filters the liquid drug prior to ejection from the ejection opening. The liquid drug cartridge can be coupled with an inhaler that includes an aerosol generator. The aerosol generator includes a vibratable membrane onto which the liquid drug is ejected. The liquid drug is aerosolized by the vibration of the membrane for inhalation by a user.Type: ApplicationFiled: July 27, 2022Publication date: February 16, 2023Inventors: Benjamin Stedman, Jim Fink, Lisa Molloy, Matt Sander

Patent number: 11285275Abstract: Self-puncturing liquid drug cartridges and an associated inhaler are used to deliver one or more separate doses of an aerosolized liquid drug. A cartridge includes a needle assembly coupled to a drug container. The needle assembly includes a hollow needle and is reconfigurable from a first configuration to a second configuration upon insertion of the cartridge into the inhaler. In the first configuration, the hollow needle does not extend into the container. In the second configuration, the hollow needle extends into the container. The inhaler includes an aerosol generator that includes a vibratable membrane that aerosolizes liquid drug ejected from the cartridge for inhalation by a patient.Type: GrantFiled: February 28, 2020Date of Patent: March 29, 2022Assignee: Aerami Therapeutics, Inc.Inventors: Benjamin Stedman, Jim Fink, Lisa Molloy

Publication number: 20210228824Abstract: A wicking member and methods of use of the same are disclosed herein. The wicking member can be a component of a medication inhaler. The medication inhaler can include a reservoir bowl defining a reservoir wherein a volume of liquid can be received. The reservoir bowl can include a top, a bottom, and a wall extending from the top to the bottom of the reservoir bowl. The medication inhaler can further include a wicking member proximate to the wall. The wicking member can extend along the wall at least partially from the top of the reservoir bowl to the bottom of the reservoir bowl. The wicking member can wick liquid to the bottom of the reservoir bowl.Type: ApplicationFiled: January 29, 2020Publication date: July 29, 2021Inventors: Ryan Patton, Benjamin Stedman, Blaine Bueche, John Patton
