PenJet

PenJet was a private U.S. medical device company focused on needle-free drug delivery systems for liquid and lyophilized pharmaceuticals. The company developed the PenJet platform, a prefilled, single-use, needle-less injector and related automated aseptic filling systems intended for pharmaceutical and vaccine delivery. Its business model appears to have emphasized technology licensing and device commercialization rather than development of proprietary therapeutics. Historical sources describe PenJet as serving pharmaceutical partners that needed alternative delivery formats for biologics and other injectables. Corporate records indicate the California entity is no longer active.
