 Atrial fibrillation (AFib)
The prevalence of and peril associated with this condition require timely and accurate diagnosis and treatment. In one of the most common electrophysiology procedures used to diagnose AFib, a doctor inserts a catheter into a blood vessel in the heart. These catheters contain small, electrode-laden wires that can be deployed after reaching the atrium to make contact with the cardiac tissue and create a map of the electrical impulses that will help doctors pinpoint the root cause of an arrhythmia, and can collapse or retract to enable insertion and removal.
An electrophysiology catheter with 64 electrodes on its deployable and retractable wires.
To improve the resolution of the cardiac map that electrophysiology catheters generate and mititgate the amount of time these procedures take, medical device designers need to increase the number of catheter electrodes by two, three, or even four times, and they need high-density connectors to do so without significantly increasing the size, weight, or flexibility of the device.
High-Density Medical Connector Design Challenges
Since the demand for high-density electrical connectors is largely fueled by the medical device market, complying with safety standards like IEC 60601 is critical.
