The human heart is a precious vessel that works hard in every moment to pump blood through the veins and delivers oxygen to the brain. For the many people who suffer from arrhythmia or an irregular heartbeat, paying close attention to the causes and any changes is literally a matter of life and death. 

This makes finding solutions to the issue critical. For those who have been unsuccessful in treating their arrhythmia with medications and have more serious risks, Ablation and specifically using a Radio Frequency Ablation system, is a promising treatment option for types of arrhythmia.

These systems are made up of a radiofrequency generator, control, and monitoring equipment as well as an antenna and cooling pump. During the procedure,  radiofrequency energy is used to emit energy and destroy heart tissue that’s causing the rapid and irregular heartbeats to happen. Once the problematic tissue is destroyed, the heart’s regular rhythm can be restored. 

Where Do Sensors Fit In?

An important step for successful RF Ablation for arrhythmias is cooling of the catheter probe. Bubble Sensors are used in the cooling pump to provide critical bubble detection in up and down streams and occlusion sensors are used to detect pressure increases in the tubing that might be indicative of tube blockages. 

While heating the problem tissue is key to destroying it and getting the heart back to a regular beating, the other arteries close by are at risk so cooling becomes important. For this part of the process, a cool liquid solution is pumped into the catheter to cool the tip during the procedure to reduce risks.

SMD Sensors has answered the call for this need in the market. Providing a combined bubble and occlusion sensors in a small form factor to fit medical devices.
