The Central Drugs Standard Control Organisation (CDSCO) is the regulatory authority for the medical device industry in India. On 13 September 2021, CDSCO specified 36 cardiovascular medical devices. This list includes devices such as Electrocardiographs (ECG), Cardiac monitors, and apexcardiographs, all of which fall under the purview of the Medical Device Rules 2017. Now, let’s look at how these devices are grouped.

CDSCO Classification and Regulation of Medical Devices

Medical devices are put into four classes: A, B, C, and D. These groups are based on how the device is used, the risk it might have, and other rules from the Medical Device Rules 2017. If someone wants to get a license to manufacture medical devices, or a license to import medical devices, they need to follow guidelines from the Ministry of Health & Family Welfare. These guidelines can change because of new technology or other updates in medical devices.

A medical device can be many things. It can be a tool, machine, implant, or even software. The main thing is that it’s used for medical purposes.

Types of Medical Devices

In India, medical devices are of two main types: Notified and Non-Notified. In the past, there were no strict rules for selling medical devices. Manufacturers could sell them without following any specific rules. But later, CDSCO made the Indian Medical Device Regulations (IMDR). With these rules, selling medical devices in India became more controlled. Now, only the notified medical devices need to follow CDSCO’s rules.

  • Notified Medical Devices: These devices require approval and oversight from CDSCO before they can be sold or used in India.
  • Non-Notified Medical Devices: These devices do not need CDSCO’s approval and can be sold without specific regulatory checks.

After 30 September 2022, all Class A & B Medical Devices become notified medical devices & after 30 September 2023, all Class C & D Medical devices will become notified medical devices. (Only applicable for devices that had been earlier classified as non-notified)

Notified Medical Devices Categories by CDSCO

There are 23 categories of Medical Devices notified by CDSCO. These are –

4Dermatological and Plastic surgery
7General Hospital/ Orthopaedic instruments
9Nephrology and Renal Care
11Obstetrical and Gynecological
15Pain Management
16Personal Protective Equipment
17Physical Support
23Non-sterile, Non-Powdered, Hand-Held, or Hand manipulated surgical instruments for general use in various surgical procedures

Classification of Cardiovascular Medical Devices by CDSCO

CDSCO has classified devices in the Cardiovascular category based on their intended use and risk class. There are a total of 36 cardiovascular medical devices classified by CDSCO. These are –

35External cardiac compressorAn external cardiac compressor is an externally applied prescription device that is electrically, pneumatically, or manually powered and is used to compress the chest periodically in the region of the heart to provide blood flow during cardiac arrest. External cardiac compressor devices are used as an adjunct to manual cardiopulmonary resuscitation (CPR) when effective manual CPR is not possible (e.g., during patient transport or extended CPR when fatigue may prohibit the delivery of effective/consistent compressions to the victim, or when insufficient EMS personnel are available to provide effective CPR).C
