Medical devices are classified according to Health Canada's risk-based system. Types of Class II medical devices include heart rate monitors, x-ray systems, and infusion pumps. Class II medical devices require a little more regulatory control to ensure safety and effectiveness. Examples include balloon catheters, prosthetic heart valves, pacemakers, etc. Class III Medical Devices Finally, devices with the highest risk for patients are categorized as Class III devices. These devices either support human life and are of substantial importance in preventing impairment of human health, or they present a potential, unreasonable risk of illness or injury. Guidance Notes GN-05 (Date of Issue: 14 Nov.2005), Section 3. The Medical Device regulations require Class II, III and IV medical devices to be manufactured (Class II) or designed and manufactured (Class III and IV) under CAN/CSA ISO 13485:2003. There are no regulatory quality system requirements for Class 1 medical devices. The U.S. Federal Drug Administration (FDA) classifies medical devices into three classes, Class I, Class II, and Class III. Class I medical devices are generally deemed low risk and Class III medical devices … They must comply with special controls set by the FDA, such as special labeling requirements, performance standards, and more.

If your medical device is a Class II device, your company will most likely need to perform a FDA 510(k) submission in order to satisfy FDA Medical Device Registration requirements for clearance to market. Class III follows the same guidelines as I and II, but also has to have pre-market approval by the FDA, a scientific review before marketing. _____ For more information For more information regarding classification of medical devices, please do not hesitate to contact the Medical Device … In other words, ensure medical devices are safe. The classification for a device depends upon the level of risk that is associated with the device. Class III Class I, II, and III Medical Devices.
