ABSTRACT:
An implanter for implanting an implant (3) in an animate being (14) includes a housing (15) on which the inner end of a hollow injection needle (2) is mounted, a plunger (6) mounted in the housing and adapted to extend into the hollow needle through the inner end of the needle, and a locking element (8, 32) for engaging with and retaining the plunger (6) against the force of compression spring (7) in a position where the plunger extends into the hollow needle for a predetermined distance. The locking element is part of a release device (9, 10; 30, 31, 33) which abuts the body (14) of the animate being when the injection needle has been introduced into the body to a predetermined depth to automatically unlock the locking element. The plunger is then forced by the spring (7) against an implant (3) disposed in operation in the injection needle for retaining the implant in the body when the injection needle is retracted from the body.
