ABSTRACT:
A method and apparatus for minimizing the potential for injury due to operation of a body-implantable device during explant manipulation thereof. In one embodiment of the invention, a body-implantable device is provided with a temperature sensor and associated monitor circuit which issues a deactivation signal when the sensed temperature falls below a predetermined threshold level. Provision is made for subsequent reactivation of the device if it is determined, for example, that sensor failure has led to spurious deactivation of the device.
