The new IMPEDE-FX comes in three sizes, the largest of which has a diameter of 12 millimeters when fully expanded. It is made of a proprietary shape memory polymer that has its development roots at Lawrence Livermore National Lab and Texas A&M University. The material is a porous polymer that can expand after being squeezed inside a catheter. The plug resumes its original shape after leaving the catheter, which was “memorized” prior to delivery.
Both the IMPEDE and IMPEDE-FX embolization plugs have the European CE mark of approval and have already been used in Europe in a number of procedures.
