Title: Shmuel Yerushalmi: Innovator in Medical Technology

Introduction

Shmuel Yerushalmi is a notable inventor based in Rehovot, Israel. He has made significant contributions to the field of medical technology, particularly in the development of pacemaker systems. With a total of 4 patents to his name, Yerushalmi's work has enhanced patient safety and device efficiency.

Latest Patents

One of his latest patents is a method and apparatus for evaluating pacer battery status and stimulation. This invention involves a pacemaker of the inhibited demand type, equipped with a battery and a pacemaker efficiency evaluator. The device features a magnetically initialized test circuit that synchronizes the timing of test stimulating pulses with the natural R-wave or the end of a basic pacemaker escape interval. This innovation enhances patient safety by avoiding competition during testing. The synchronized test circuit produces an alternating sequence of sensing and pacing periods maintained throughout the test duration. Upon actuation of the test, the first R-wave or the end of the basic pacer interval is sensed, and a series of stimulating pulses is applied at the end of successive test intervals. The duration of these intervals indicates the battery status, and this sequence is repeated during the magnet test.

Another significant invention is a micropower system that provides a stabilized voltage output at a predetermined voltage higher than that of the energy source. This system is powered by one or more primary cells in parallel or by a suitable battery. It is particularly useful for systems requiring low power at stabilized voltage, which is substantially independent of energy source impedance and load variations. The output voltage stabilization is controlled by a voltage detection circuit based on C-MOS inverters, allowing for extremely low power drain. This system is especially valuable for use with electronic implantable devices such as cardiac pacemakers.
