Title: Innovations by David C Amundson

Introduction

David C Amundson is a notable inventor based in Saint Paul, MN (US). He has made significant contributions to the field of cardiac technology, holding a total of 3 patents. His work focuses on improving the functionality and efficiency of cardiac pacemakers.

Latest Patents

One of his latest patents is the Atrial Rate Sensitive Cardiac Pacer Apparatus. This innovative electrical pacer device responds to cardiac demand, allowing it to adjust the cardiac output accordingly. It detects changes in the fundamental period of the atrial electrical cycle, averaging these changes over a predetermined time interval. The resulting control signal is utilized to raise and lower the ventricular heart rate, thereby increasing or decreasing the cardiac output. Additionally, this device continuously drives the ventricular rate toward a predetermined lower rate, known as the at-rest rate, on a time cycle significantly longer than the aforementioned predetermined time interval.

Another significant patent is the Implantable Electrode. This improved electrode is designed for delivering electrical stimulation pulses or signals to an organ, such as the heart, from an electrical pulse generator. The electrode is typically exposed to the organ being stimulated and is electrically coupled to a conductive lead extending from the pulse generator. It features a body that substantially envelops the lead and comprises a plurality of electrically conductive metallic filaments compressed together to form a generally fibrous body. These filaments have a mean effective diameter of less than about 100 microns and constitute about 3% to 30% of the total volume of the fibrous member.
