Abstract
A mechanically operable handpiece is provided which allows a physician to easily deliver repeated, incremental doses of a beneficial composition, for example, a dermal filler gel, superficially into skin.
Claims10
A device for delivering repeated doses of a composition into skin, the device comprising:
- a handpiece comprising a main housing having a housing distal end;
- a cartridge suitable for containing a composition and having a cartridge distal end configured to be coupled to a needle;
- a plunger movable within the cartridge, and having a distal portion defining a head and a proximal portion defining a drive rack;
- a shuttle, movable within the main housing and structured to receive the cartridge;
- and
- retention clips for holding the shuttle forward in the housing and drive clips engaging the drive rack;
- the device being structured and configured to allow one-way, incremental movement of the plunger each time the device is device actuated, thereby allowing delivery of repeated doses of the dermal filler into skin.
