Abstract

1400070 Heart stimulators AMERICAN OPTICAL CORP 18 Aug 1972 [19 Aug 1971] 38596/72 Heading A5R A heart stimulator for use external to the body is battery powered and includes means for temporarily supplying power during battery replacement, said means may comprise a capacitor, rated for example at 25 volts, 100 mircofarads, in parallel with the battery. A demand pacemaker of the type disclosed in Specification 1266907, wherein, in order to provide appropriate transistor baising, three batteries are connected in series, may be modified to embody the present invention by individually shunting some of the batteries by respective capacitors in addition to providing a capacitor shunted across the series circuit of all the batteries.
