Johnson & Johnson's Medical technology arm received FDA approval for a new workflow that will make it safer for medical professionals to treat atrial fibrillation, a condition that makes your heartbeat irregular and can cause stroke or heart failure. Several products developed by Biosense Webster, which is part of J&J MedTech, got the OK for a "zero fluoroscopy workflow" from the FDA, meaning live X-ray imaging will no longer be needed during catheter insertion procedures. Instead of using X-rays to insert Biosense catheters, medical professionals can now use ultrasound to guide treatments.
