  • Needle insertion and retraction mechanism
    Patent number: 10646643
    Abstract: A system and method are provided for preventing a sharp stick hazard from a needle tip of an automatic injector device. In some embodiments, a skin contact surface of the device is attached to an injection site, for example by an adhesive. Optionally a locking mechanism holds a needle extended into an injection site. A body of the device is optionally movably attached to the skin contact surface. Pulling the body away from the injection site optionally moves the body with respect to the skin contact surface. Movement of the body with respect to the skin contact surface optionally moves interlinked parts of the locking mechanism, releasing the locking mechanism.

  • Syringe device with a dose limiting mechanism and an additional safety mechanism
    Patent number: 10220155
    Abstract: A syringe device for ejecting a dose of a medicament, the syringe device comprising: a dose limiting mechanism arranged to interact with a dose ejecting mechanism to prevent ejection of a dose exceeding a set dose, and a safety mechanism, which is arranged such with respect to the dose ejecting mechanism that, if the dose limiting mechanism fails, the safety mechanism prevents ejection of a dose exceeding the set dose.

  • Myocardial injector
    Patent number: 7803136
    Abstract: A device is provided for performing intra myocardial injections. The device comprises a needle, a catheter formed with a lumen, and an abutment member mounted within the lumen for axial movement. The abutment member is movable between a first configuration, wherein it is substantially tube-like and is positioned within the lumen of the catheter, and a second configuration, wherein it extends beyond the distal end of the catheter and is substantially radially flared. Before the needle is advanced to perform an injection, the abutment member is moved to its second configuration to prevent contact between the catheter and the myocardial tissue during the injection.
