China NMPA Product Recall - PTA dilation catheter (trade name: PowerCross)

Ev3 Inc., a medical device manufacturer, initiated a voluntary recall for its PowerCross PTA Dilatation Catheter, as reported by China's National Medical Products Administration (NMPA) on December 22, 2016. The recall stemmed from a discovery, made during routine product inspections and formally reported on November 28, 2016, that the catheter's outer shaft experienced squeezing and deformation at the proximal connection of the balloon. This defect could restrict the internal lumen, potentially leading to critical issues such as the balloon failing to inflate, slow deflation, or complete inability to deflate after inflation. An internal investigation revealed the root cause as a manufacturing process deviation: a new operator failed to adhere to standard procedures during the balloon pleating process, inserting the product too far into the machine. Although Ev3 Inc. promptly initiated this recall under the NMPA's regulatory framework, it was confirmed that none of the affected PowerCross catheters were ever imported into or sold within China. Therefore, while provincial regulatory bodies were informed for oversight, no specific corrective actions were necessary for the Chinese market. The primary impact of this recall was on products distributed in other regions, notably the United States.
