Provided herein are a system (100), method, and apparatus for delivering a therapeutic device (140), e.g. an embolic coil, from a delivery tube (102) at a target site in a patient's body. A heating element (112) is disposed in the delivery tube that can be actuated remotely, and a layer of low temperature adhesive (160) is applied at the heating element to retain the therapeutic device. The kicker in the form of, for example, a compressed spring (150) is mounted within the delivery tube so as to be in contact with the therapeutic device for applying a constant ejector force that is countered by the adhesive force of the low temperature adhesive. When the heating element is actuated, the spring's ejector force overcomes the softened adhesive's adhesive force to force the therapeutic device out of the delivery tube.
