An Overview of Classification of Medical Devices by CDSCO
The rules regarding different classes of medical devices were published by the Central Government in 2017. The term ‘Class’ is very important in these rules because different rules and procedures are prescribed for different classes of medical devices but it was not explained clearly which device falls into a particular class. This ambiguity makes it difficult to properly implement these rules. To solve this problem, the Medical Device Division of Central Drugs Standard Control Organization of India (CDSCO) issued a notice in 2020 and properly classified the medical devices into different categories and four classes which are A, B, C, and D. In this article we are going to discuss the same and explain every technicality involved to make it easier for you to understand.

What is Medical Device?
Before categorizing them into classes, we should understand what medical device actually is that we are referring to again and again. It is defined under the Medical Devices Rules of 2017. The definition includes in vitro diagnostic devices, surgical dressings, surgical bandages, surgical staples, surgical sutures, ligatures, blood collection bags, blood component collection bags mechanical contraceptives, intrauterine devices, disinfectants, insecticides and other devices as notified by the central government from time to time. IVDs stand for In-vitro diagnostics, which are tests used to detect diseases, conditions, and infections. In-vitro means 'in glass', which means that the tests are usually done in test tubes and similar equipment.
Classification of Medical Devices
For their registration, certification and licensing purposes, medical devices are divided into four groups based on their level of risk. These groups are named Class A, B, C, and D. Class A devices are considered to have the lowest risk while Class D devices have the highest risk. To determine which class a medical device belongs to, there are specific rules called the Medical Devices Rules, 2017, which include a list of parameters. These parameters vary depending on the type of device (in-vitro or other medical devices) and take into account the device's intended use. If two separate devices are used together, they are both classified under the same risk class.
Use of Classification of Medical Devices
These classes are used in the application form to get a manufacturing licence for medical devices in India. Different forms are used to apply for medical devices of different classes. The process can be completed online through the CDSCO portal. A certificate is provided for the license of manufacturing these medical devices for separate classes after the successful completion of the process.
