Systems and techniques for explanting implantable devices are described. In one aspect, a device includes an explant tool configured to explant an implantable device from a body. The explant tool includes an elongate shank comprising a forward portion defining a longitudinal passage and a front tip attached to the forward portion and defining an opening to the longitudinal passage defined by the forward portion. The front tip comprises a slanted surface that slopes in a direction so as to spread tissue during forward penetration of the front tip into the body.
