Catheter Electrodes

Fluoroscopic view of catheter ablation

Catheter electrodes are small, specialized medical devices used in various diagnostic and therapeutic procedures. The electrodes are usually inserted into the body through a catheter, a thin tube guided to the appropriate location by a physician. Catheter electrodes are used in various medical procedures, including electrophysiology studies, ablation therapy, and mapping of cardiac arrhythmias.

The most common type is the diagnostic catheter electrode, which records electrical signals from the heart or other organs. These electrodes are typically made of a metal such as gold or stainless steel and are coated with an insulation material to prevent electrical current from leaking out. They are connected to a monitoring device that records the electrical signals and displays them on a screen for the physician to interpret.

Another type is the ablation catheter electrode. These electrodes are used in ablation therapy, which involves destroying small areas of tissue in the heart or other organs to correct abnormal electrical signals. Ablation catheter electrodes are typically made of a metal such as platinum or iridium and are heated to high temperatures to destroy the targeted tissue.

Catheter electrodes can also be used in a procedure called mapping. This procedure involves creating a detailed map of the electrical activity in the heart or other organs. Mapping catheter electrodes are typically made of a metal such as gold or stainless steel and are equipped with multiple sensors to record electrical signals from different locations.

Catheter electrodes are highly specialized devices that require precise manufacturing and quality control. They must withstand the harsh conditions of the human body and maintain their integrity during the procedure. They must also be flexible and small enough to navigate the body’s natural pathways and reach the specific target area.

In conclusion, catheter electrodes are medical devices that are critical in various diagnostic and therapeutic procedures. They are inserted into the body through a catheter to record electrical signals, destroy targeted tissue, or create detailed maps of the electrical activity in the heart or other organs. Therefore, they require precise manufacturing and quality control to ensure their safety and effectiveness.
