   The PFx Closure System is a novel percutaneous system that employs radiofrequency (RF) energy to effect closure of a PFO by welding the tissues of the septum primum and septum secundum together. This minimally invasive system achieves closure utilizing percutaneous entry without the necessity of an implantable device. Furthermore, the procedure is performed exclusively from the right atrial side of the septum, reducing the potential complications associated with left atrial catheterization.
The PFx Closure System is composed of the PFx Catheter, ThermaFuse™ Generator, and a vacuum pump. The procedure utilizes a combination of suction and the application of radiofrequency energy to close the PFO using tissue welding without requiring an implant device. |
