China NMPA Product Recall - Nickel-titanium alloy support system

OptiMed Medizinische Instrumente GmbH, a German medical device manufacturer, initiated a voluntary Class II recall of its Nickel-Titanium Alloy Stent Systems on August 17, 2015. This action, overseen by the National Medical Products Administration (NMPA) of China, addressed a critical issue where some of these vascular stents failed to deploy or fully deploy during implantation. The primary concern was that incomplete deployment could necessitate additional medical intervention, potentially leading to complications such as stent elongation or breakage during the procedure. An investigation, prompted by product complaints, confirmed the defect in specific models like the sinus-SuperFlex-635 stent of a certain length. This recall applied globally, with 98 units sold in China across specific affected batches, including Q007630 to Q015123 for model 8606-7200, and Q007618, Q008654 for model 8607-7200. In response, the NMPA mandated several actions. All units involved were required to immediately cease the sale and use of the affected stent systems and disseminate the recall notification to relevant distributors and end-users. Furthermore, the manufacturer, OptiMed, was responsible for collecting and ensuring the proper disposal of all unused recalled products. It was clarified that this issue only affects devices during the implantation phase and does not pose a risk to patients who have already successfully received the stent.
