In Shanghai, China on December 12, 2018, the self-developed VitaFlow^® II Transcatheter Aortic Valve and Recyclable Delivery System of MicroPort Cardioflow has been admitted into the “Green Path”from National Medical Products Administration (NMPA) for the special approval procedure for innovative medical devices. 

The VitaFlow^® II System is able to recapture a released valve through its innovative sheath design, which means the valve can be re-aligned and re-released. This will resolve the problem of “difficult alignment” to a large extent, meet the requirement for accuracy of interventional surgery, effectively improve the success rate of surgery, provide convenience for surgeons and facilitate a large-scale clinical promotion. The reinforced inner and outer catheter structure has realized 360-degree bending function while ensuring a stable and accurate release, enabling the valve to smoothly pass through different types of aortic arches, and thus reducing damages to the blood vessel. Given the characteristics of old patients whose femoral artery is thinner, the design of inline catheter sheath has realized an integrated puncture function, direct establishment of vascular access, a smaller incision and effective reduction of peripheral vascular complications.
