1. A hand-held injection device for soft tissue comprising:
- a cartridge suitable for containing an injectable material and couplable to a needle;
a shell structured to contain the cartridge;
a drive mechanism including a motor and a piston for moving the injectable material from the cartridge through the needle;
a power source for activating the drive mechanism; and
a user-programmable controller coupled to the drive mechanism, where a user-defined injection rate of the injectable material can be set;
wherein the device is capable of injecting the injectable material at the user-defined injection rate at a force of up to about 50 Newtons.

Abstract
Described herein are injection devices capable of automatically injecting substances into the soft tissue of a patient. The devices can inject low to high viscosity materials at predetermined, user selected injection rates, allowing the operator more control than a traditional syringe. The devices can allow mixing of more than one substance and/or reconstitution of a solid substance for injection. The injection devices described herein can allow the operator to easily inject one or more low to high viscosity liquid or gel soft-tissue augmentation fillers, one or more drugs, one or more other biocompatible materials, or combinations thereof.
