02.Expert Discussion
Professor Lu Xinwu:As the promoter of the integration of medicine and engineering for S-wan™, Professor Lu Xinwu clearly pointed out that the core objective of S-wan™ product design primarily addresses two clinical challenges: First, in-situ fenestration of the aorta—traditionally, a tortuous angle greater than 60° has been considered a surgical contraindication, but the application of S-wan™ is expected to transform this scenario into a feasible indication. Second, in arch fenestration surgeries, for cases with poor side-posterior positioning or arch morphology, S-wan™ also provides a solution.
Zhang Yan JiaoGrant:The development of vascular sheaths is crucial for establishing minimally invasive surgical access, providing a foundation for subsequent treatments. She compared the vascular sheath to a staff in traditional weaponry, emphasizing that while it is not aggressive, it can evolve into various uses. Through observation and experimentation, Professor Zhang Yan affirmed that the S-wan™ Bipolar Adjustable Sheath possesses dual-axis bidirectional adjustment capabilities, significantly enhancing the diversity of shape transformation. When handling complex operations in endovascular interventional procedures such as crossing obstacles and super-selective catheterization, the multi-directional adjustment function of S-wan™ offers operators a wider range of operational angles and shape options, thereby simplifying the surgical process.
Professor Mingjin Guo：Arteries with a high degree of morphological distortion often present significant operational difficulty and positioning challenges in interventional procedures due to their complex anatomical structure. The design of the S-wan™ sheath, which offers multi-angle adjustability, is expected to enhance operational flexibility and precision in such cases. Specifically, when managing arch lesions, the non-contact operation mode of the S-wan™ sheath has the potential to reduce intraoperative complications, including the risk of stroke, by minimizing the danger associated with plaque dislodgement.
Professor Zhang Zhang：The product not only has a poetic name, drawing inspiration from the image of "swan" in English, reflecting the ingenious design, but also excels in performance. Professor Zhang reviewed the experience of using the sheath, emphasizing that it significantly improved the convenience and success rate of surgeries when dealing with arteries that are complex in angle and difficult to access. He believes that the practical application of this product demonstrates the significant progress made by domestically produced medical devices in terms of technology and quality.
Professor Chaowen Yu:S-wan™ can effectively address the super-selective challenges of tortuous branch vessels. With the increasing number of total endovascular branch vessel reconstruction surgeries, the application of the S-wan™ sheath is expected to significantly improve the accuracy of branch vessel selection and the success rate of surgeries, especially in complex cases such as type III arch.
Professor Yao Kai:S-wan™ Demonstrates Clinical Application Value in Managing Tortuous Abdominal Aortic Branch Vessels. Additionally, the data platform equipped with S-wan™ can recommend appropriate curvature adjustment solutions to physicians by analyzing different vascular morphologies. This data support plays a significant role in assisting with specific surgical procedures. Professor Deng Hongping: In arch vessel surgeries, particularly in complex scenarios like in-situ fenestration of the subclavian artery, the application of the S-wan™ sheath provides an effective solution to the common challenges of difficult angulation and selection during these procedures.
The attending guests, Professor Hua Zhaohui, Professor Qi Youfei, and Professor Zhao Zhen, all highly praised the S-wan™ Bipolar Steerable Sheath and expressed their anticipation for its rapid routine application in clinical practice.
