Implantationsenhed

The invention relates to an implanter for implanting an implant in an animate being, comprising a housing (5) mounting one end of a hollow injection needle (2) and further a plunger (6) adapted to extend into the hollow needle from the end of the hollow injection needle that is turned towards the housing. The plunger is retained by locking means (8) against the pressure of spring means (7) in a position where the plunger extends into the hollow needle over a predetermined distance. The locking means comprise unlocking means (10) which abut the body of the animate being when the injection needle has been introduced into the body to a predetermined depth and subsequently automatically unlock the locking means. This causes the plunger to be pressed by said spring means against an implant (3) disposed in operation in the injection needle for retaining the implant when the injection needle is being retracted from the body. A loading device (20) is to be used with an implanter according to the invention.
