1. An implant device delivery and release apparatus comprising:
- an implant device;
a pusher member having a proximal end and a distal end; and
a coupling section configured to attach the implant device to the distal end of the pusher member, the coupling section comprising a thermally responsive member, and a coupler adopted to receive the thermally responsive member, wherein the thermally responsive member is held by the coupler by an application of energy and is released from the coupler by discontinuing the application of energy.

Abstract
The present invention provides for implant device delivery apparatuses and related methods of use. An apparatus of the present invention may include a pusher member selectively engaged to an implant device. The implant device may be, e.g., a coil. A coupling section of the apparatus allows the implant device to be secured to the pusher member via an application of energy. When it is desired to disengage the implant device, such as after locating the implant device at a target cavity site, the application of energy is ceased and the implant device may be disengaged from the pusher member.

9. A method for delivering an implant device using a pusher member having a proximal end and a distal end, the method comprising:
-
affixing the implant device to the distal end of the pusher member by applying energy to the pusher member;
introducing the implant device into a body having a target cavity;
advancing the implant device to the target cavity; and
detaching the implant device from the distal end of the pusher member by discontinuing the application of energy to the pusher member. - View Dependent Claims (10, 11, 12, 13)

14. An implant device delivery and release apparatus comprising:
-
an implant device;
a pusher member having a proximal end and a distal end; and
a coupling section configured to couple the implant device to the distal end of the pusher member, the coupling section comprising a thermally responsive member, a retaining sleeve surrounding the thermally responsive member, and a tether detachably engaged between the thermally responsive member and the retaining element, wherein the implant device is coupled to the pusher member by an application of energy to the coupling section and is released from the pusher member by discontinuing the application of energy. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
