China NMPA Product Recall - Implantable neurostimulation electrodes

On July 20, 2016, the National Medical Products Administration (NMPA) issued an alert regarding a voluntary recall initiated by Medtronic Inc. and its Chinese entity, Medtronic (Shanghai) Management Co., Ltd. The recall, detailed in NMPA Index No. JGXX-2016-10185, concerned specific batches of implantable neurostimulation electrodes (models 3387S-40 and 3389S-40, CFDA Registration No. 20123213291). The primary issue identified was damage to the electrode insulation material discovered during the manufacturing process, affecting batches VA15GPJ, VA15K3N, and VA15K7K. While Medtronic's investigation confirmed that no affected products had left the factory, the company proceeded with a voluntary recall of potentially impacted unused batches in the market as the root cause analysis was ongoing. Notably, these recalled products were not sold or imported into China; the recall was limited to the United States. Consequently, no corrective actions were deemed necessary for electrodes already in use, nor were further actions required within China. The NMPA, however, directed provincial food and drug administrations to enhance their supervision of such medical devices.
