1. A system for transcutaneously implanting a medical device, the system comprising:

  • an introducer having at least a portion engageable with at least a portion of a medical device, wherein the introducer comprises a shape memory alloy having a predetermined activation temperature range,wherein the introducer, at a temperature below the predetermined activation temperature range, is in a first shape memory state configuration in which the introducer includes a first transition bend adjacent to a straight proximal portion of the introducer, andwherein the introducer, at a temperature above the predetermined activation temperature range, is in a second shape memory state configuration in which the introducer includes a second transition bend adjacent to a straight distal portion of the introducer; and

    an activating component to change the temperature of the introducer to transition the introducer from the first shape memory state configuration to the second shape memory state configuration, wherein said transition changes the shape of the introducer and translates the medical device engaged with the introducer from a position above the skin surface to a position at least partially through the skin surface;

    wherein said transition is driven by a martensitic-to-austenitic change of the shape memory alloy.
