1. An inserter device for a medical device comprising:
- a housing;
a carrier body for the medical device to be inserted, the carrier body is movable relative to the housing and comprises a penetrating member defining a direction of insertion, and a first locking member configured to releasably hold the carrier body relative to the housing;
a second body movable relative to the housing; and
driving means which move respectively the carrier body body and the second body relative to the housing;
the driving means comprising a single spring unit placed between the carrier body and the second body, the driving means configured to first move the carrier body in the direction of insertion and then to move the second body in a direction which is in an angle of about 180°
±
5°
to the insertion direction to distance the second body from the carrier body;
wherein the first locking member releasably holds the carrier body in a retracted position relative to the housing while the driving means are in a biased state.
