Claim:
1. A jet injector, comprising: a prefilled syringe comprising: a housing that houses the prefilled syringe and is configured for allowing insertion of the needle at the injection location to an insertion point that is at a penetration depth below the surface at the insertion location; a syringe support supportively mounting the prefilled syringe to the housing; and an energy source configured for biasing the plunger with a force selected to produce an injecting pressure in the medicament in the fluid chamber that substantially remains between about 80 p.s.i. and 1000 p.s.i. during injection of the medicament to jet inject the medicament from the fluid chamber through the needle to the injection site; wherein the penetration depth and injecting pressure are sufficient to substantially prevent backflow of the injected medicament.
