Why do we need regulation?
Australian doctor William McBride alerted
the world to the dangers of thalidomidein the 1960s which triggered the need for
an Australian regulator of therapeutic goods.
“In recent months I have
observed that the incidence of
multiple severe abnormalities
in babies delivered of women
who were given the drug
thalidomide (‘Distival’) during
pregnancy, as an anti-emetic
or as a sedative, to be almost 20%.”

What is a medical device?
Any instrument apparatus, appliance, material or other article
(whether used alone or in combination, and including the software
necessary for its proper application) intended to be used for human
beings for:
• diagnosis, prevention, monitoring, treatment or alleviation
of disease;
• diagnosis, monitoring, treatment, alleviation or
compensation for an injury or handicap;
• investigation, replacement or modification of the anatomy or
of a physiological process;
• control of conception; or
• an accessory to an instrument, apparatus, appliance,
material or other article mentioned above
It may not achieve its principal intended action by
pharmacological, immunological or metabolic means, but may be
assisted by such means
Bandages
Dental implant
Breast implant
Glucose monitor
Defined in s41BD of the Therapeutic Goods Act 1989
www.hydrix.com Commercial-in-Confidence
Articles declared not to be medical devices
Therapeutic Goods (Articles that are not Medical Devices) Order No. 1 of 2010
declares that the following are not medical devices:
� Chemical oxygen generators
� In-vivo imaging agents
� Product intended to deliver a medicine, where the medicine and device
are a single integral product (which is not reusable)
� Products incorporating tissues, cells, substances of human origin
� Products incorporating viable tissues, cells, substances of animal origin
� Hospital and household grade disinfectants
www.hydrix.com Commercial-in-Confidence
Software – is it a medical device?
A software product is a medical device if it meets the definition of a medical
device (s41BD of the Therapeutic Goods Act 1989)
Examples A software product that is
limited to managing and
presenting information
(e.g. records management
system or dosage
calculator) would not
normally meet the
definition unless it also
incorporates a therapeutic
or diagnostic function
• Mobile app used to measure blood glucose levels for
monitoring diabetes
• Software which analyses and interprets ECG signals
• Software running an infusion pump to control dose

Good design or bad design?
www.hydrix.com Commercial-in-Confidence
What is the cost of bad design?
A report by the FDA shows a 97% increase in recalls of medical devices between fiscal years 2003 and 2012.
FDA researchers found that software design failures accounted for the most common recall causes, making up about 15% of all device recalls between 2010 and 2012.
The cost of rework, re-design and re-submission can kill companies!
www.hydrix.com Commercial-in-Confidence
Technical documentation
Technical documentation for the design of the device must be
held by the manufacturer and may be reviewed by the TGA for
compliance with the Essential Principles
