Publication number: 20250107843Abstract: An anchored cardiac ablation uses a catheter having an ablator head having ablator elements, or petals and an anchor. The catheter is advanced in the PV and expand the anchor in the PV; the ablation head is opened once in the PV, to reach the PV walls; the ablation element is pulled back in operating position, keeping the anchor in place. When the ablation head reaches the region of the vein ostium, the diameter of the ablation elements increase, and the user stops pulling back. The ablation element is moved toward the ostium, positioning the ablation elements on the tissue to be treated; desired target tissue is ablated; the ablator and anchor are collapsed into resting positions and withdrawn from the PV.Type: ApplicationFiled: July 23, 2024Publication date: April 3, 2025Inventors: Marwan ABBOUD, Douglas WAHNSCHAFFE

Patent number: 11357563Abstract: A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system may include controller that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.Type: GrantFiled: October 16, 2017Date of Patent: June 14, 2022Inventors: Marwan Abboud, Rachid Mahrouche, Chadi Harmouche, Teresa Ann Mihalik, Gilles Desrochers
