ABSTRACT
Controllable jet injection could provide a fast, repeatable method for delivery of small volume, high viscosity drugs to the dermis. We have developed a compact, lightweight jet injector that uses a small commercial rotary motor and differential screw to create a jet of fluid with sufficient force to deliver drug into tissue. Clear tissue analogue and ex vivo tissue were used to demonstrate repeatable delivery of <;10 µL of fluid using the device. The fluid when forced through a narrow orifice (108 µm) reaches a velocity of >250 m/s with an injection time of <;3 ms.
