Title: Innovations by Alexander Medvedev

Introduction

Alexander Medvedev is an accomplished inventor based in Orange Village, OH (US). He has made significant contributions to the field of medical devices, particularly in the development of heart assist technologies. With a total of 2 patents, his work focuses on enhancing the functionality and safety of blood pumps used in left ventricular assist devices (LVADs).

Latest Patents

One of his latest patents is a "Chronic performance control system for rotodynamic blood pumps." This invention involves a rotodynamic blood pump powered by a brushless DC motor, which is regulated by a power supply. The system utilizes three feedback channels to monitor voltage, current, and motor speed, allowing a microcontroller to analyze these parameters. This analysis helps determine motor input power, patient heart rate, current pump flow rate, and systemic pressure. The microprocessor calculates a desired flow rate proportional to the patient's heart rate and communicates the necessary power output to a commutation circuit, ensuring optimal pump performance while incorporating essential safety checks.

Another notable patent is the "Method and system for controlling blood pump flow." This invention focuses on a heart assist device, such as an LVAD, which is controlled based on the ratio of the pump's speed to the patient's heart rate. By defining the patient's activity and required cardiac assist level through heart rate and pump speed, the device can adapt to changes in the patient's activity level, enhancing its responsiveness and effectiveness.
