The group's principal activity is to develop, manufacture and sell the injex system, a patented, needle-free drug delivery system. The injex system consists of a hand-held, spring-powered device that injects drugs from a needle-free syringe through the skin as a narrow, high-pressure stream of liquid. The group presently operates through two wholly owned subsidiaries: equidyne systems inc & equidyne holdings. The group's customers include pharmacy chains and distributors to such chains.
