Title: Innovations by Jan Ljungstroem: Pioneering Mechanical Defibrillation

Introduction

Jan Ljungstroem, an inventive mind from Solna, Sweden, has made significant contributions to the field of medical technology. With a remarkable portfolio of nine patents, he is especially known for his innovative solutions in defibrillation methods aimed at improving cardiac resuscitation techniques.

Latest Patents

Among Ljungstroem's latest endeavors are groundbreaking patents that focus on mechanical defibrillation. His patent for a mechanical defibrillator introduces an implantable heart defibrillator that utilizes a shock pulse generator to deliver a mechanical shock to the heart. The unique feature of this device is its electromechanical energy converter that generates pressure via a piezoelement in a pressure chamber. This pressure is transmitted through a fluid in an electrode resembling a hydraulic line, leading to a balloon-like electrode head that interacts directly with heart tissue. The generated pressure causes the electrode head to expand, delivering a mechanical shock that facilitates defibrillation.

Another noteworthy patent involves a sophisticated defibrillation system housing, which connects at least two defibrillation electrodes. One of these electrodes is designed for intracardiac placement and features a flexible electrode cable with electrically insulated conductors. This system comprises control components to determine the timing of defibrillation therapy, ensuring optimal delivery of defibrillation pulses while minimizing risk to the heart.
