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.
Claims15
A hand-held injection device for soft tissue comprising:
- a cartridge suitable for containing a dermal filler material and couplable to a needle;
- a shell structured to contain the cartridge;
- a motorized drive mechanism;
- a power source for activating the drive mechanism;
- a user-programmable controller coupled to the drive mechanism, where a user-defined injection rate can be set;
- a vial, suitable for containing a dilutant for the dermal filler material, fluidly coupled to the cartridge;
- a pump and a one-way valve for directing the dilutant into the cartridge to be mixed with the dermal filler material;
- and
- a plunger actuated by the drive mechanism for forcing the dermal filler material mixed with the dilutant from the cartridge and out of the needle at the user defined injection rate.
