Abstract
A jet injection device with a fluid chamber in a housing member for holding about 0.02 ml to about 3 ml of a medicament. An injection-assisting needle has an injection end that extends from the housing for inserting into a patient to a depth of up to about 5 mm. A force-generating source is configured to apply a pressure reaching about 100-1000 psi to the medicament in the chamber to expel the medicament through the injecting end of the needle.
