Covellus' patented Modular Catheter Architecture is a new design and use paradigm for endovascular and other minimally invasive surgical device catheters. Our first product is the Modular Balloon System, which uses conventional .035 PTA balloons to let physicians build all the Balloon Catheter Solutions they would typically need in peripheral endovascular procedures plus Balloon Solutions not available through conventional designs... all at the point of care. The Modular Balloon System can create Balloon Catheter Solutions adaptable to any Cath Lab operations, with customization options for a physicians practice and procedures. It is a dramatic shift from the undifferentiated PTA balloon products available today.
