Patent ID: 8790293

Claim:
An injector device comprising: a syringe barrel defining a central axial cavity, and having a distal end and a proximal end; a cannula needle having a distal end and a proximal end and defining a central axial cavity in communication with the central axial cavity of the syringe barrel; a retracting element coaxially coupled to the proximal end of the cannula needle adapted to retract the cannula needle into the syringe barrel; a plunger having a distal end and a proximal end, disposed in the central axial cavity of the syringe barrel at a fixed position therein, and, when the cannula needle retracts, extending through the central axial cavity of the cannula needle and beyond the distal end of the syringe barrel; and an implant disposed in the central axial cavity of the cannula needle between the plunger rod and the distal end of the needle.
