TORONTO – The 2-French Electrophysiology Catheter (2F) had its Canadian launch in mid-December at Toronto’s Sunnybrook Health Sciences Centre where electrophysiologist Benedict Glover used it to map the small, tortuous branches of the coronary sinus in a patient suffering from cardiac arrhythmia. Developed by Toronto-based Baylis Medical Inc., the 2F is expected to work in tandem with the company’s larger 6F catheter to help diagnose comparatively rare but complex heart arrhythmias.
