GMDN Term Definition:
A mains electricity (AC-powered) bedside
device designed to continuously detect,
measure, and display a patient's
electrocardiogram (ECG) through leads and
sensors attached to the patient; it also
typically displays heart rate. The device is
typically equipped with audible and/or
visual alarms that are triggered when the
patient's parameters drop below or exceed
pre-set limits.

By clinical application (e.g., cardiovascular devices)
By name (e.g., prosthesis, scissors, catheter)
By attribute (e.g., Material, Invasiveness,
sterility, Use frequency)

GMDN Agency working with the FDA
Leverage of UDI data for device registries
Started with “RAPID project” (Pilot study MDEpiNet)
Trial project for peripheral vascular intervention
(PVI) registry
Focus on peripheral stents
FDA have now created a “Learning UDI Community”
initiative with a focus on GMDN led device
categorisation
Helping to improve GMDN definitions and user assignment of terms.

Golden rule
Every device (that is placed on the market separately)
should be assigned to a single GMDN term that
represents that device explicitly
![Page 36: Global Medical Device Nomenclature (GMDN)70 national Medical Device Regulators 4000+ Manufacturers worldwide US FDA implementation of UDI Rule All medical devices sold in the US will](https://reader035.fdocuments.in/reader035/viewer/2022062505/5eba2efa6ff66511171bce8e/html5/thumbnails/36.jpg)

Common mistake 2
Multiple terms assigned to a device ( often with kits, systems or implant sets)
Example (in GUDID):
![Page 38: Global Medical Device Nomenclature (GMDN)70 national Medical Device Regulators 4000+ Manufacturers worldwide US FDA implementation of UDI Rule All medical devices sold in the US will](https://reader035.fdocuments.in/reader035/viewer/2022062505/5eba2efa6ff66511171bce8e/html5/thumbnails/38.jpg)
Common mistake 2
56284
Drug-eluting coronary artery
stent, non-bioabsorbable-
polymer-coated A sterile non-bioabsorbable metal tubular mesh structure covered with a non-bioabsorbable polymer and a drug coating that is designed to be implanted, via a delivery catheter, into a coronary artery (or saphenous vein graft) to maintain its patency typically in a patient with symptomatic atherosclerotic heart disease. The drug coating is slowly released and intended to inhibit restenosis by reducing vessel
smooth muscle cell proliferation. Disposable
devices associated with
implantation may be included.
Multiple terms assigned to a device ( often with kits, systems or implant sets)

Common mistake 3
Judging the term by the name without review of the definition
Ophthalmic use
33961
General surgical procedure kit,
non-medicated, single-use A general-purpose collection of various sterile surgical
instruments, dressings, and materials intended to
be used to assist a range of
surgical procedures across
multiple clinical specialities. It does
not contain pharmaceuticals. This is a single-use device.
Is this term more appropriate?
Ophthalmic surgical procedure kit, non-
medicated, single-use

Search first – if cant find suitable term use Enquiry.
Enquiry is the only way to get help from the GMDN Agency
for assigning Terms to products. The outcome will be:
An appropriate existing Term.
Modification of an existing Term to include the new product’s
characteristics.
A new GMDN Term is created.
