PMDA: Executes medical device evaluations, authorizations, and post-market monitoring.
The Japan Medical Device Nomenclature (JMDN) system classifies medical devices for approval and regulation
Classification of Medical Devices in Japan-Japan Device Regulations Guide
Japan categorizes medical devices according to their danger to human health, akin to the systems employed by the United States. The European Union (EU) and the U.S. Food and Drug Administration (FDA) are also involved. These categories influence the approval process and the regulatory obligations for each device. We categorize devices into four types based on their level of danger.
1. Class I (General Medical Devices): These devices pose minimal risk to patients. Examples encompass stethoscopes and surgical devices. Class I devices often have a more straightforward registration procedure.
2. Class II (Controlled Medical Devices): These devices present a low to moderate level of risk. This class includes items like contact lenses and specific varieties of catheters. Class II devices need third-party certification instead of a comprehensive evaluation by the PMDA.
3. Class III (Specially Controlled Medical Devices): Due to their effects on the human body, these medium-risk devices, including implanted pacemakers, require strict PMDA approval.
4. Class IV (Highly Controlled Medical Devices): These high-risk devices, such as heart valves, that maintain or sustain life require a comprehensive PMDA examination and substantial clinical evidence before approval
Enrollment and Authorization Procedure
Before any medical device is sold or marketed in Japan, it must complete a clearance procedure determined by the product’s risk category.
1. Pre-market Notification (Todokede Process):
The Todokede method, applicable to Class I devices, is a simple registration that does not need PMDA evaluation. Manufacturers must send a notification to the PMDA prior to the gadget’s commercial introduction.
2. Pre-market certification (Ninsho Process):
Class II devices need certification from a certified third-party organization rather than the PMDA. The Ninsho method is more expedient and less intricate than the comprehensive Shonin approval process.
3. Pre-Market Approval (Shonin Process):
Class III and IV devices need the Shonin approval procedure, entailing a comprehensive PMDA evaluation of the product’s clinical safety, effectiveness, and quality data. Clinical studies are frequently essential to verify adherence to Japanese safety regulations.
The pre-market review procedure is both time-intensive and expensive, yet it guarantees that high-risk products comply with Japan’s stringent regulations.
