A skeletal tissue stimulator and especially a bone growth stimulator 10 and a circuit 12 adapted to be coupled to the skeletal tissue in a body, and especially bone tissue in the body, whose growth is to be stimulated, which tissue acts as a load 22 for the circuit 12. The circuit 12 has a battery 24 and an oscillator circuit 26 which is adapted to be coupled to the load 22. The oscillator circuit 26 is coupled to a storage device 28 which is charged from the battery 24 and discharged through the load 22. The storage device 28 controls the state of the oscillator circuit 26 which in turn controls current flow from the battery 24 directly through load 22. The bone growth stimulator 10 and circuit 12 are characterized in that all the current provided by the battery 24 must flow through the load 22, either directly from the oscillator circuit 26 or as a result of discharge from the storage device 28.
