Hi Phillip I was a pacemaker recipient for many years before transplant and had about 10 ablation I forget how many . The last one being in 2017. I can't say I've heard of a multipoint system but you never know what has been invented over the last 4 years. Same thing Jennifer said a great question for a EP Cardiologist who specialize in those areas. I've had the pleasure to have had some great ones. Are you currently looking at an ablation yourself? What kind of condition are you being treated for. My area that gave me problems was Vintricular Tachycardia and had both a pacemaker with defibrillator and had the unpleasant shocks to many times to count. Hence the reason I ultimately received a Heart Transplant. I look forward to hearing more about your search.
Blessings
