< Purpose >
For patients with severe calcification, proximal distortion or chronic occlusion in percutaneous coronary intervention (PCI). When the catheter is unable to continue to enter the pathological location, the tunnel catheter is inserted into the catheter. The tunnel catheter has better flexibility and smaller external diameter, which can establish an extended delivery channel so that the stent can be transported to the pathological location.
< Advantage >
? Exclusive 5.5F specifications, to adapt to more serious lesions;
? 35D soft head design greatly reduces the injury of vascular wall;
? Good push and flexibility;
? Wire winding technology, good flexibility and support strength;
? Hydrophilic coating to improve transportability through complex and tortuous lesions.
< Specification type >
Y4S55-5.5F、Y4S60-6.0F.
