Patent ID: 7998108

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 coaxially coupled to the distal end of the syringe barrel, and defining a central axial cavity in communication with the central axial cavity of the syringe barrel; a plunger having a distal end and a proximal end, disposed in the central axial cavity of the syringe barrel, and extending beyond the proximal end of the syringe barrel when fully depressed; a pusher rod coupled to the distal end of the plunger and adapted to enter the central axial cavity of the cannula needle when the plunger is depressed into the syringe barrel; a stop disposed at the proximal end of the cannula needle, coupled to the distal end of the syringe barrel, and having a portion that extends beyond a cross section of the needle; a disengageable catch coupled to a portion of the plunger and that blocks the plunger from entering the syringe barrel beyond a pre-determined point; an implant disposed in the central axial cavity of the cannula needle between the pusher rod and the distal end of the needle; and a disengageable block that obstructs the implant from exiting the distal end of the cannula needle the block having a first end that penetrates the distal end of the cannula needle and a second end secured to an outside portion of the injector device.
