Basic information

    Valvuloplasty rings are essential high-value implantable devices used in cardiac surgery to treat mitral and/or tricuspid regurgitation. Like artificial heart valves, it is another type of heart valve treatment product. Valvuloplasty mainly treats patients with valve annulus disease or valvular insufficiency caused by other heart diseases. The biggest advantage of this product is that it can restore the function of the native valve through the correction of the valve annulus. There is no need to worry about the threat of many complications after surgery like mechanical valve replacement; nor is it like having to worry about possible replacement again like with biological valve replacement. valve. At the same time, the treatment fee is reduced by half, which is particularly important to alleviate the "expensiveness of medical treatment". A large group of clinical follow-up data shows that for patients with indications for valvuloplasty, implanting an artificial heart valvuloplasty ring to treat valvular insufficiency is currently recognized as a treatment option with ideal long-term results.

Performance advantages

• The annulus structure is composed of a thin-walled medical polymer support tube and its inner core as the annulus, which ensures the repair of diseased or deformed valve annulus, while also meeting its three-dimensional flexibility and maintaining compliance with the myocardium.
• The outer part of the ring support tube is covered with a layer of soft and elastic medical polyester braid. This layer of braid not only ensures optimal adhesion between the annulus and the annulus tissue, but also has excellent biocompatibility. Animal experiments have confirmed that the artificial valve annulus can be fully covered by the endocardium 3 weeks after being implanted.
• The annular body of the valve annulus is clearly distinguishable under X-ray, making it easier to conduct postoperative review.
• Elastic rings of various specifications are placed on a ring holder with a physiological valve orifice shape, and there are marking lines at the triangular distance between the left and right fibers of the ring body. The transparent ring holder facilitates the operator to observe the anatomical structure under the ring, making the implantation position of the artificial valve ring more accurate.
• Equipped with ring testers of various specifications, the shape of which is the same as the ring setting groove of the ring holder. Cardiac surgeons can conveniently, quickly and accurately determine the size of the artificial valve ring to be selected based on the left and right fiber triangle marks on the ring tester, improving the efficiency of the device. Surgery success rate.
