Safety and Efficacy of TaurusOne® Transcatheter Aortic Valve System in Patients With Severe Calcific Aortic Stenosis

The TaurusOne® Transcatheter Aortic Valve System consists of an aortic valve, an associated delivery catheter and a loading system. The aortic valve consists of a self-expanding nitinol frame, a sealing skirt and valve leaflets, which are made of bovine pericardium. The delivery system is mainly composed of conical head, opacity ring, inner tube, top ring, middle tube, outer tube, booster rod, stress diffusion catheter, handle, etc. The outflow end of the aortic valve is provided with three fixing holes evenly distributed on the circumference on the top ring of the delivery catheter, so as to facilitate the installation, delivery and release of the aortic valve. Before the operation, the aortic valve needs to be installed into the sheath of the delivery catheter as required.
