Android Assassin teleport bracelet

A teleport was owned by the Doctor who stole it from Android Assassins who had captured him.

It had lost its power to teleport, but as the Doctor was nano-seconds from getting killed, he channeled their blasts of energy meant to kill him into his sonic screwdriver and into himself, and before it could kill him, used the teleporter that had recharged by their blasts, to teleport away, and saving his own life.
