Medical Device Notes

Ireland is a major exporter of medical devices in the EU and globally.
The Irish Medical Device Association (IMDA) represents the medical technology industry in Ireland.
There are over 300 medtech companies in Ireland, employing around 25,000 people.
Annual value of Irish medtech exports is significant.

A medical device includes any product (excluding medicines) used in healthcare for diagnosis, prevention, monitoring, or treatment of illness or disability.
EU Definition:
- Includes instruments, apparatus, software, implants, reagents, etc., intended for medical purposes like diagnosis, treatment, or modification of anatomy.
- Does not achieve its primary action through pharmacological, immunological, or metabolic means.
- Includes devices for conception control and products for cleaning/sterilization of devices.
US Definition:
- Similar to the EU definition, covering instruments, apparatus, implants, reagents, etc.
- Intended for use in diagnosing, treating, or preventing disease, or affecting the body's structure/function.
- Does not achieve its primary purpose through chemical action or metabolism.

EU Definition:
- Includes reagents, kits, instruments, software, or systems used in vitro for examining specimens from the human body.
- Provides information on physiological/pathological states, congenital impairments, predisposition to diseases, safety/compatibility with recipients, treatment response, or therapeutic measures.
US Definition:
- Reagents, instruments, and systems for diagnosing diseases or determining health states.
- Used for collecting, preparing, and examining specimens from the human body.

Implants, dressings, patient monitoring equipment, X-ray systems, wheelchairs, hearing aids, and blood glucose measurement devices.

Software with a medical purpose that is not incorporated into another medical device.
Examples include mental health apps, medical imaging software, stand-alone software for segmentation and 3D printing, heart rate measurements and cloud-based ECG interpretation.
Decision-making process:
- If the software program performs an action on data for the benefit of an individual patient, it may be considered a medical device.

Medical Devices Regulation (MDR EU) 2017/745
In Vitro Diagnostic Medical Devices Regulation (EU) 2017/746
These regulations govern the clinical investigation, production, and distribution of medical devices in Europe.

Improved performance of notified bodies.
Clearer requirements for clinical data.
More specific product requirements (including Unique Device Identifier - UDI).
Improved pre-market assessment of high-risk devices.
Enhanced market surveillance.
Improved governance, coordination, and cooperation through EUDAMED (European Database on Medical Devices).

Devices are grouped into four classes based on risk:
- Class I: Low risk.
- Class IIa: Medium risk (short-term use).
- Class IIb: Medium risk (long-term use).
- Class III: High risk.

Class Is (sterile): sterile gauze, personal protection kits, stethoscopes, examination gloves, colostomy bags, or oxygen masks
Class Im (measuring): thermometers, droppers, and non-evasive blood pressure measuring devices
Class Ir (reusable): surgical instruments, endoscope
Class I (non-sterile, nonmeasuring, or non-reusable surgical instrument): bandages, compression hosiery, walking aids, wheelchair, hospital beds
Class IIa devices: hearing-aids, blood transfusion tubes, and catheters
Class IIb Devices: ventilators and intensive care monitoring equipment
Class III Devices: balloon catheters, prosthetic heart valves, pacemakers, etc.

Class I: Low risk, general controls.
Class II: Moderate/controlled risk, may require 510(k) clearance (substantially equivalent to a predicate device).
Class III: High risk, requires PMA (premarket approval) with reasonable assurance of safety and efficacy.

The European and U.S. medical device markets are substantial, with significant annual values.
Figures for 2018-2025 (projected) show the market size in USD billion for various countries and the U.S.

Manufacturers, importers, and device user facilities (e.g., hospitals) have requirements for reporting adverse events related to medical devices to the FDA.
