Thoracic aortic disease is a serious disease that threatens human health and longevity. With the increase of age, the incidence rate increases year by year; therefore, more individualized requirements for endovascular coated stent implantation and in situ fenestration (ISF) of the left subclavian artery (LSA) have been put forward. The current problem of 6 difficult puncture of ISF and complications related to branch stent implantation have limited the success rate and popularity of this technique. In response to the above situation, by using our original aortic Fan’s classification method, our research group has developed a new ISF device, namely KAPOK system. Altering the twisted vessel with a traction device to make puncture easier, and using a “hat” branch stent that clamps on the main stent, so that there is no residual stent in the aortic lumen. In vitro models and animal experiments are used for verification. The device is expected to reduce the difficulty of the procedure and the occurrence of complications, increase the popularity of the procedure, provide an effective channel for other later interventional therapies, and bring benefits to human health and longevity. Related patent and product model have been basically completed. The research group has been formed.
