Electrodes for Medical Devices to Assure Accurate Diagnosis

An electrode is a solid electric conductor through which electric current enters or leaves an electrolytic cell, other medium, or the non-metallic part of a circuit. Electrodes used in medical devices convert ionic potential into electric signals and are generally made up of metal, lead, or gel. 


How They Work

The electrode used in medical devices transfers ionic current in the body and allows surface quantification of currents, which are amplified to diagnose several nervous, muscular, and cardiac disorders. 

Surface electrodes are aids to find bioelectric abilities from the surface of the body. For example, an electrocardiography (EEG) evaluates electric activity of the heart and needs 12 to 15 surface electrodes for diagnosis. 

Needle electrodes are inserted into the body to get localized measurement of potentials from a specific muscle. For example, an electromyography (EMG) uses a needle electrode to assesses muscular response to electrical activity of a specific muscle. 

Microelectrodes consist of small tips that can be penetrated through a single cell to take readings. 

Wireless Monitoring Pacemaker

Recently, Boston Scientific Corporation developed the “ESSENTIO MRI” and “ACCOLADE MRI” pacemakers, integrated with LATITUDE NXT patient management system. These provide wireless remote monitoring for speedier detection and intervention and improved patient outcomes. The Atrial Arrhythmia Report can be accessed using these pacemakers, which provides a complete view of the AT/AF status of a patient and any other information required for assessing the efficacy of AF treatment. 

A recent clinical study on the use of Remote Monitoring (RM) technology within cardiac rhythm devices exhibited that patients not under remote observation are at greater risk of mortality than those frequently tracked with automatic daily monitoring. 

Market Overview

Increasing prevalence of heart diseases and neurological disorders has resulted in extensive use of ECG and EEG devices, thereby driving demand for electrodes. According to a report by Grand View Research, Inc., the global electrodes for medical devices market is predicted to gain nearly USD 2.0 billion by 2025. 

North America is anticipated to dominate the market during the forecast period (2014 to 2025) due to increasing prevalence of CVDs. Prominent players in the market include GE Healthcare, 3M Healthcare, Boston Scientific Corporation, Medtronic, and Philips Healthcare.
