Patent ID: 8500681

Claim:
An injection system comprising: an injector device having a first cavity in fluid communication with an orifice, the orifice configured for needle-less injection such that a fluid contained in the first cavity can be ejected through the orifice into an injection site; and a fluid transfer device having a second cavity containing injectable material, a third cavity containing injectable material, a distal end, and a proximal end, the second cavity being sealed from the proximal end by a first seal in an initial position, the third cavity being sealed from the second cavity by a second seal in the initial position and the third cavity being sealed from the distal end, the fluid transfer device being configured to mix the injectable material contained within the third cavity with the injectable material contained within the second cavity in a mixing position to form a mixture, the first seal slideably coupled with the injector device proximate the orifice in the initial position and a transfer position, the orifice extending into the proximal end and the second cavity being in fluid communication with the first cavity in the transfer position, and the fluid transfer device being removeable from the injector device upon transfer of the mixture from the second cavity to the first cavity.
