Title: Innovations of Robert A. Walters in Cardiac Technology

Introduction

Robert A. Walters is a notable inventor based in Pittsburgh, PA, who has made significant contributions to the field of cardiac technology. With a total of 10 patents to his name, Walters has focused on developing advanced pacemaker systems that enhance patient care and improve the functionality of cardiac devices.

Latest Patents

Among his latest innovations is a pacemaker with a circuit for pulse width modulating stimulus pulses. This implantable pacemaker features circuit means that indicate, through pulse width modulation of the delivered pacing pulses, the programmable control states that manage the selected operating parameters of the pacemaker. The design includes a parallel to serial shift register that receives control states from a pacer circuit and generates a serial multiple bit word when the pacemaker is switched to a magnetic mode. The shift register is clocked by stimulus timing signals, and the output drives a one-shot generator, which combines with the timing pulses to produce pulse width modulated pacing pulses. Another significant invention is a programmable atrio-ventricular pacer, which utilizes a single programming circuit to provide program control signals for separate ventricular and atrial pacing circuits. This innovative design allows for the derivation of atrial timing signals from the same clock signal used for ventricular stimulus pulses, employing a programmable digital multiplier in combination with a counter to set the atrial escape interval independently.
