Title: Innovations by Richard J Wessels in Cardiac Device Technology

Introduction

Richard J Wessels, an accomplished inventor based in Scandia, MN, has made significant contributions to the field of medical technology, particularly in cardiac devices. With three patents to his name, his work focuses on improving the efficiency and safety of cardiac therapies.

Latest Patents

One of Wessels' latest innovations is a patented low-energy atrial cardioversion therapy system. This implantable therapy generator is equipped with sensing circuitry that detects cardiac signals from both atrial and ventricular activity. It features detection circuitry connected to the sensing circuitry and control circuitry that manages the generation and selective delivery of a multi-stage atrial cardioversion therapy to implanted electrodes. Each stage delivers multiple pulses that include high-frequency sub-pulses. The therapy circuitry incorporates a high-voltage charging circuit that charges a storage capacitor to a predetermined voltage, facilitating precise control over the delivery of therapy through a delivery capacitor.

Another notable invention is a system and method for discriminating high-frequency electromagnetic interference (EMI) from cardiac events. This method allows implantable medical devices to identify and filter out EMI signals that could interfere with detecting physiological parameters. By passing components through specific filters, the device can differentiate between physiological signals and EMI, significantly enhancing the reliability of cardiac monitoring.
