Fabrication of a Lead Head Made of the Carbon-Fiber-Reinforced Composite for the Temporary Cardiac Pacemaker

Abstract

Compared with traditional leads, carbon fiber composite leads have a series of advantages such as lightweight, soft texture, and high conductivity. In this experiment, we attempted to improve the existing carbon-fiber-based TTCP metal leads by using carbon-fiber-graphene-woven leads or conductive cloth, so as to solve a series of defects of TTCP metal leads commonly used in the clinical temporary cardiac pacemaker. We performed a series of measurements, including resistance comparisons and stability checks on the finished product characteristics. The results showed that the resistivity of the whole lead did not change significantly after modification, and the carbon fiber bundle was stable and easily deformed under lower stress to reduce the damage to the myocardium, which had excellent clinical application value.
