Publication number: 20250050025Abstract: An exemplary embodiment of an injector includes a trigger mechanism, an energy source, and a user-operable firing-initiation member. The trigger mechanism can include a floating trigger member having a retaining portion, a ram assembly having a ram configured to pressurize a medicament container for expelling a medicament therefrom, the ram assembly further having a floating trigger engagement member configured to engage the retaining portion of the floating trigger member when the floating trigger member is in a pre-firing condition. The energy source can be associated with the ram for powering the ram to expel the medicament, and the user-operable firing-initiation member can be operable for causing an axial rotation of the floating trigger member from the pre-firing condition to a firing condition in which the floating trigger engagement member is released from the retaining portion to allow the energy source to fire the ram.Type: ApplicationFiled: October 25, 2024Publication date: February 13, 2025Applicant: Antares Pharma, Inc.Inventors: Thomas Kramer, Matthew H. Rust, Paul M. Goudreau, Peter A. Hoeft, Julius C. Sund, Peter L. Sadowski, Michael Travanty, Patrick Madsen

Publication number: 20230109835Abstract: An injector (10) for injecting a medicament into a patient. The injector includes a container (18) defining a first chamber (22), which contains a fluid therein, and a second chamber (23). The injector also includes an injection conduit (126) configured for directing the fluid fired from the container into the patient. A transfer mechanism is operable by a user to transfer the fluid from the first chamber to the second chamber in a first stage of operation, and a firing mechanism is operable by the user for firing the fluid from the second chamber through the injection conduit in a second stage of operation. An energy source (62) is in powering association with the firing mechanism to drive firing mechanism in the first and second stages.Type: ApplicationFiled: December 13, 2022Publication date: April 13, 2023Applicant: Antares Pharma, Inc.Inventors: Thomas E.
