Important considerations
Medical devices are classified according to the level of harm they may pose to users or patients.
The following tool will assist in determining the classification of a medical device that is not an In Vitro Diagnostic device.
There are separate classification rules for IVD devices.
Medical Device Classification | Level of potential harm |
---|---|
Class I | Lowest |
Class Is, Class Im | Low |
Class IIa | Low to Moderate |
Class IIb | Moderate to High |
Class III | High |
Some things to note before you start
- Medical devices are classified according to their intended purpose, as specified by the manufacturer.
- Where a device has more than one specified purpose, the correct result will be based on the purpose with the highest classification. For example, a catheter that is intended to be used short-term in peripheral arteries would be a Class IIa device. One that is intended to be used in the central circulatory system, would be a Class III device. If a manufacturer produced a catheter that was intended to be used in both the peripheral and central circulatory systems, it would be Class III because this is the highest classification for the device's intended purpose.
- Where more than one classification rule applies to the device, the correct classification is the highest classification. For example, a device used in surgery that depends on a source of energy would be covered by both 'invasive' device rules and 'active' device rules.
- Where a device is used in combination with another medical device, the classification rules must be applied separately to each device. This includes any accessories to the medical device.
- Where a medical device is driven or influenced by an item of software that is not embedded in the device, the software has the same classification as the medical device. This includes Apps on a mobile device like a smart phone or tablet.

Which group does your medical device belong to?
Is your device invasive or non-invasive?
Non-invasive devices
May come into contact with a patient or they may not, but they do not penetrate the body of a patient.
This means they do not enter any body orifices such as the mouth or nostrils; they do not touch the eyes; and even though they may come into contact with injured skin, they do not pierce the skin in any way.
Invasive medical device
Is intended by the manufacturer to be used, in whole or in part, inside the body of a human being.
This includes devices that enter a body orifice or that penetrate the surface of the body, or that enter the body in the context of a surgical operation.
A medical device that touches the surface of the eye, such as a contact lens, is in a body orifice.
Based on the above definition, what type of device do you think you have?
Non-invasive devices
Non-invasive medical devices can be grouped into the following:
- devices that are intended to channel, store or modify blood, liquids or gases, or that are intended to store body tissues or organs, that will be introduced into the body
- devices that are intended to contact injured skin such as bandages or wound dressings
- other non-invasive devices
Based on the intended purpose of your non-invasive device, which category is appropriate?
Non-invasive - Other
Other purposes for non-invasive devices include collecting body liquid for liquids that won't be re-infused, immobilising or supporting body parts, providing physical support for patients, assisting in diagnosing a patient or providing patient treatment.
Examples of other non-invasive devices
Urine collection bottles, ostomy pouches, incontinence pads or collectors used with wound drainage devices, bandages used to aid the healing of a sprain, casts for fractured limbs, cervical collars, gravity traction devices, compression hosiery, patient hoists, walking aids, wheelchairs, stretchers, corrective glasses, stethoscopes, surgical drapes, conductive gels and electrodes for EEG or ECG.
Supplied sterile
A medical device that is sterilised before it is released by the manufacturer is 'supplied sterile'.
Some medical devices must be sterilised before they are used, even though they are new from the manufacturer. These are not supplied sterile.
Is your non-invasive medical device supplied sterile?
Non-invasive - In contact with injured skin
Medical devices that are intended to be in contact with injured skin may be intended to:
- provide a mechanical barrier, or compression, or absorb exudates from a wound
- manage the micro-environment of a wound, for example by keeping it moist
- be used for wounds that have breached the dermis and can only heal by secondary intent
Examples of devices in this category include gauze pads, adhesive bandages, elastic bandages, hydrogels, and barrier creams.
Devices which replace injured skin and remain in place after the procedure are implantable. If this applies to your device, you should go back and select 'invasive device'.
Which of the above purposes is your device intended for?
- Purpose 1- Mechanical barrier, compression, absorption and is NOT supplied sterile
- Purpose 1 - Mechanical barrier, compression, absorption and IS supplied sterile
- Purpose 2 - Managing the micro-environment of a wound
- Purpose 3 - To be used on wounds that have breached the dermis
- Another purpose not specified above
Non-invasive - Handle or modify substances for administration to a patient
Devices in this category are primarily intended to:
- channel or store blood or body liquids that will be infused, administered, or introduced into a patient, or
- store an organ, part of an organ or body tissue that is to be later introduced into a patient (this includes containers and any liquids, gels, or other storage media), or
- channel or store a liquid or gas that is to be infused, administered, or introduced into a patient (this includes devices that may be connected to an active medical device that is Class IIa or higher), or
- modify the biological or chemical composition of blood, other body liquids, or other liquids intended to be infused into a patient, only by filtration, centrifugation or exchanges of gas or heat.
- modify the biological or chemical composition of blood, other body liquids, or other liquids intended to be infused into a patient, by any means other than filtration, centrifugation or exchanges of gas or heat.
Examples of devices in this category:
Drug delivery systems, breathing circuits, syringes for infusion pumps, devices intended for storage of organs or tissues for transplantation (this includes containers and any liquids, gels or other storage media), refrigerators intended for storing blood, hemodialysis machines, devices used for particulate filtration of blood in an extracorporeal circulation system, centrifugation of blood for transfusion or autotransfusion, removal of carbon dioxide from the blood and/or adding oxygen, and warming or cooling blood in the extracorporeal circulatory system.
Based on the above, what is the intended purpose of your device?
Invasive device
Invasive in a body orifice or surgically invasive?
Body orifice:
- means a natural opening, or a permanent artificial opening, in a human being's body; and
- includes the external surface of a human being's eyeball
This type of medical device only enters a natural orifice such as the nasal cavity or the mouth, or a permanent created orifice; it does not cut through the surface of the body or any surface of the orifice.
Surgically invasive:
These types of medical devices are intended to be used with the aid, or in the context, of a surgical operation; and includes devices that penetrate the body in any way other than by entering a body orifice.
Based on the above definitions, how is your device intended to be invasive?
Invasive in a body orifice - Connected to an active device
Some invasive devices that enter body orifices may be connected to an active medical device.
What is an active medical device?
An active medical device is one that is intended by the manufacturer to:
- depend for its operation on a source of electrical energy or other source of energy (other than a source of energy generated directly by a human being or gravity), and
- act by converting this energy.
Active medical devices do not include medical devices that are intended by the manufacturer to transmit energy, a substance, or any other element between an active medical device and a human being without any significant change in the energy, substance or other element being transmitted.
Class IIa or higher active devices include those that are intended to diagnose, treat, or monitor patients by delivering or exchanging energy with the patient, or that are intended to deliver or remove medicine or other liquids to or from a patient.
Invasive in a body orifice - location and duration
The classification of body orifice invasive devices depends on the duration of use and where they are used in the body.
Duration
Transient use
Intended to be used continuously for less than 60 minutes.
Short‑term use
Intended to be used continuously for at least 60 minutes but not more than 30 days.
Long-term use
Intended for continuous use for more than 30 days.
Based on the above, which is the correct combination of duration and location for your device's intended use?
- Transient use in any body orifice, or short-term use in the mouth, nasal cavity or ear canal
- Short-term use in any body orifice other than the mouth, the nasal cavity or the ear canal
- Long-term use in the mouth or ear canal
- Long-term use in the nasal cavity and not likely to be absorbed by the mucous membranes there
- Long-term use in the nasal cavity and may be absorbed by the mucous membranes there
- Long-term use in any body orifice other than the mouth, nasal cavity or ear canal
Surgically invasive - duration of use
Surgically invasive medical devices can be grouped according to the intended duration of use. The classification of a device is based on the longest duration of intended use for the device.
Duration of use
Transient use
Less than 60 minutes of continuous use
Short-term use
Continuous use from 60 minutes up to 30 days
Long-term use
Continuous use for more than 30 days

Active devices - Active implantable medical devices
Active implantable medical devices are active devices that are intended to be wholly or partially placed into the body, including a body orifice, and to remain there after the procedure.
Active devices - software and programmed devices
There are classification rules that apply to active medical devices that are:
- software (including Software as a Medical Device)
- programmed
- programmable.
The terms ‘programmed’ or ‘programmable’ are intended to capture hardware active medical devices incorporating software or any other form of software-type instruction set (such as field programmable gate arrays).
Active devices that are software and programmed - Is it for a relevant health professional only?
For software-based medical devices (including those that can be programmed) that provide a diagnosis or screen for a disease or condition, the classification depends on whether:
- the information is provided to a relevant health professional to decide, or
- the software makes the decision, or the information is provided to a person other than a relevant health professional to decide.
The term ‘relevant’ describes the health professional with the appropriate expertise intended to use the provided information to assist them in making a diagnosis. The information provided by a medical device under this classification rule is not to be solely relied upon for the diagnosis.
For example, a relevant health professional for diagnosis and treatment recommendations for certain forms of cancer would be an oncologist, whereas a general practitioner would not be considered to be a relevant health professional in that case.
A general practitioner could be a relevant health professional for diagnosing other sorts of diseases and conditions.
Active devices that are software and programmed

In some cases, the administration or removal of the medicine, body liquids or other substances is potentially hazardous to the patient, having regard to the nature of the substances involved, the part of the patient's body concerned, and the characteristics of the device.
Examples of active devices for administering medicine or other substances that could potentially be hazardous to the patient include infusion pumps, anaesthesia equipment, dialysis equipment, hyperbaric chambers and nebulisers where the failure to deliver the appropriate dosage characteristics could be hazardous.
Is your device likely to deliver or remove medicine or other substance to or from a patient in a potentially hazardous way?
Active devices for diagnosis
Active devices for diagnosis are intended to supply information for the purpose of detecting, diagnosing, monitoring, or treating physiological conditions, states of health, illnesses, or congenital deformities.
These devices may be intended to:
- illuminate a patient's body in the visible spectrum
- supply energy that will be absorbed by a patient's body
- image in vivo distribution of radiopharmaceuticals in a patient
- allow direct diagnosis or monitoring of vital physiological processes of a patient
- monitor vital physiological parameters of a patient, where the nature of any variations monitored are of a kind that could result in immediate danger to the patient (for example, variations in cardiac performance, respiration, activity of the central nervous system)
- emit ionising radiation and to be used for diagnostic radiology
- control or monitor, or directly influence, the performance of a device that emits ionising radiation for diagnosis.
Examples of active devices for diagnosis
Magnetic resonance imaging equipment, diagnostic ultrasound, evoked response stimulators, gamma cameras, electronic thermometers, stethoscopes and blood pressure monitors, electrocardiographs, monitors/alarms for intensive care, biological sensors, oxygen saturation monitors and apnoea monitors.
Which of the above intended purposes is relevant for your active device for diagnosis?
Active devices for therapy
Active devices for therapy are intended to support, modify, replace or restore biological functions or structures for the purpose of treating or alleviating an illness, injury or handicap.
These devices may be intended to:
- administer energy to a patient or exchange energy to or from a patient
- administer or exchange energy to or with a patient in a potentially hazardous way considering the nature, density and site of application of the energy
- control or monitor, or directly influence, the performance of a device that delivers or exchanges energy to or with a patient in a potentially hazardous way.
Some examples of active devices for therapy (non-hazardous energy delivery) include devices for therapeutic massage, muscle stimulators, powered dental hand pieces, hearing aids, neonatal phototherapy equipment and ultrasound equipment for physiotherapy.
Some examples of active devices for therapy (potentially hazardous energy delivery) include electrocautery devices, UV or laser light devices for corneal modification, baby incubators, external pacemakers and defibrillators, lithotriptors, therapeutic X-ray and other sources of ionizing radiation.
Which intended purpose is relevant for device?
Is your active device supplied sterile?
Supplied sterile
A medical device that is sterilised before it is released by the manufacturer is 'supplied sterile'.
Some medical devices must be sterilised before they are used, even though they are new from the manufacturer. These are not supplied sterile.
Active device - measuring function
Measuring function
A medical device has a measuring function if the device is intended by the manufacturer to measure:
- quantitatively a physiological or anatomical parameter; or
- a quantity, or a qualifiable characteristic, of energy or substances delivered to or removed from the human body.
Based on the above, does your medical device include a measuring function?
