Title: Improvements in or relating to muscle stimulation devices
Inventor: FULLER DENNIS QUINTRELL
IPC: A61N1/372
Filed: 1962-11-24
Abstract: An implanted pulse generator, used as a cardiac pacemaker, has means whereby one of its characteristics, such as frequency or amplitude, may be varied by means located outside the body.  In circuits described, relaxation oscillators lators are used in which the frequency of oscillation is determined by the progressive rise in voltage of the emitter of a transistor.  The voltage at which the transistor conducts, to effect a changeover in the oscillator, may be influenced by a superimposed voltage derived from a rectified R.F. signal obtained from an external transmitter.  The circuit may be arranged so that such signals reduce and/or increase the frequency of the pacemaker.  It is also proposed to introduce a semi-conductor, the impedance of which is variable by means of an applied magnetic field.  This may be incorporated in the circuit to vary the frequency or amplitude of the oscillator output and is controlled by a magnet placed outside the body.
