PERKAT works together with the current IABP technique (intra aortic balloon pump with about 200,000 cases p.a. internationally) and is the only-one catheter-based & self-expanding, pulsatile & ECG-triggered, cost-effective heart pump technique with a high pump performance. PERKAT is not available on the market so far. Articles in leading scientific journals and presentations at the top four international cardiology conferences in the last years show the medical need, the development status and the technological and medical advantages of PERKAT.
