Laser ablation catheter HeartLight®

pulmonary veinballoon

A disposable, 12F, multi-lumen catheter has an inflatable balloon at its distal end made of a compliant material and specially shaped to provide wide areas of contact surrounding the pulmonary vein ostium. The balloon size is dynamic as a function of the pressure used to provide inflation; as a result it can span from under 20 mm to over 30 mm in diameter making a single catheter able to span a wide range of vein sizes. An Arc Generator laser delivery fiber, included with the catheter, provides the conduit to deliver a 30-degree arc of laser energy. The Arc Generator is advanced through the central lumen of the Balloon Catheter and can be moved and rotated to adjust the location of energy delivery. The fluid within the balloon is used to cool the arc generator and passes through the central lumen of the catheter as it re-circulates through the compliant balloon. Separate lumens are available for balloon inflation/deflation, endoscope access and illumination.
