Thermometer implants

Thermometer implants comprising a thermometer body, the thermometer body enclosing a channel and a bulb, the channel being terminated by the bulb at an end, the channel and the bulb containing a fluid, the fluid expanding and contracting along the channel to a fluid length which is functionally related to a target temperature of the bulb at a target time, the thermometer body being adapted to be located in a subject body from where the fluid length is not visible at the target time, and thermometer body properties and fluid properties together making possible measurement of the fluid length outside of the subject body, the thermometer implant, and wherein the thermometer body encloses a sequent channel and a sequent bulb, the sequent channel being terminated by the sequent bulb at an end, the sequent bulb and the sequent channel containing a sequent fluid, the sequent fluid expanding and contracting along the sequent channel to a sequent fluid length which is functionally related to a sequent target temperature of the sequent bulb at a sequent target time, the sequent fluid length being not visible at the target time, and sequent fluid properties making possible measurement of the sequent fluid length outside of the subject body.
