Introduction

Ashok P Nedungadi is a notable inventor based in Lake Oswego, OR (US). He has made significant contributions to the field of medical technology, particularly in cardiac impedance sensing and energy transmission for implantable devices. With a total of 2 patents, his work reflects a commitment to advancing healthcare solutions.

Latest Patents

One of his latest patents is titled "Method and apparatus for cardiac impedance sensing." This invention involves a method for measuring the impedance of heart tissue or leads associated with a cardiac stimulation apparatus. The process includes charging a capacitor, storing the voltage across it when charged, discharging the capacitor into the lead/heart system, and storing the voltage when discharged. The two voltages are then used to determine the combined impedance of the lead and heart tissue. This method can be effectively accomplished by using separate circuits to measure each voltage and applying them to an analog-to-digital converter for digital conversion.

Another significant patent is the "Data communication system for control of transcutaneous energy." This system is designed for controlling energy transmission to an implantable medical device. It features an implantable device with rechargeable batteries and a single coil for both energy transmission and data telemetry. The control circuitry in the device senses battery voltage and current, encodes these values, and transmits them through the coil to an external energy transmission device. This external device receives the encoded signals and transmits energy back to the implantable device, ensuring efficient operation.
