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
