A medical pacing wire comprising a clamp that is adapted to be moved between an open position and a closed position and further adapted to allow a user to attach an electrode to a living tissue. In particular embodiments, the medical pacing wire may include a memory shape alloy having a memory state, which is adapted to cause the clamp to move from the closed position toward the open position when the memory shape alloy is caused to move from a non-memory state to the memory state. Also, in some embodiments, the clamp may comprise a superelastic material, and the medical pacing wire may be adapted to allow a user to remotely cause the clamp to substantially release the living tissue that has been closed within the clamp without substantially damaging the living tissue.
