  • Patent number: 12377253
    Abstract: Embodiments of the invention relate to an applicator for inserting an implant under the skin of a patient. The applicator comprises a housing containing a cannula that is fixed to a cannula holder and is slidably received within said housing. The cannula comprises an aperture at its distal end and a lateral opening. The implant is accommodated within the cannula and/or the cannula holder. A securing mechanism retains the implant inside the cannula. This mechanism comprises an arm configurable between a first position, which prevents the implant from exiting through the cannula's aperture, and a second position that enables the implant's placement under the skin through the aperture. Said lateral opening is situated between the aperture and the distal end of the implant. In the first arm position, the arm partially enters the lateral opening, thereby obstructing the implant from exiting through the aperture.
