purposes by chemical action or
by being metabolized.
- As simple as a tongue depressor
or a thermometer
- As complex as robotic surgery devices

Notified Bodies
Designated and monitored by competent authorities
Assessment of QMS and design dossier (class III) or
technical file (class IIa, IIb: sampling)
Prior assessment of changes to QMS or MD design
Periodic surveillance inspections of manufacturer
Certificates with limited validity / renewal
Basic Principle
• Labeling
- Label
- Instructions for use
- CE-marking
• Registration and Listing
- Manufacturers / authorized representatives
- MD of class I
9
28/09/2012
Where to adjust the balance
between both necessities?
• Pre-market control
- risk related classification
- fast introduction of innovation
• Post-market control
- surveillance
- vigilance
Post-market safety
• Obligations of manufacturers
- Post-market surveillance plan, incl. post-market
clinical follow-up
- Reporting of serious incidents to CA
- Application of Field Safety Corrective Actions
(FSCA)
- Communication of FSCA to users by means of
Field Safety Notice (FSN)
10
28/09/2012
Post-market safety
• Responsibilities of competent authorities
- Central recording and evaluation of reported
incidents and FSCA
- Information sharing between competent
authorities (NCAR system)
- Market surveillance
◦ Measures against non-compliant MD
◦ Measures against dangerous products
Strengths
• Flexibility
• Timeliness
• Cost-effectiveness
• Balance between pre- and post-market
control
• Manageable for SMEs
11
28/09/2012

Overview and status
of GHTF
Global Harmonization Task Force
Call for Harmonization
The call for harmonization of regulatory
approaches is coming from many sectors :
• Governments
• Industry
• Public
14
28/09/2012
Why Harmonize?
• Regulatory harmonization should :
• Provide consistent application of regulatory
principles and approaches
• Improve regulatory system effectiveness
and efficiency
• Reduce duplication
• Rationalize time and costs
• Allow new products/technologies to enter
the market place
• Create transparent regulatory processes
Potential Challenges to
harmonization
• Differences in delegation of regulatory
authorities between levers of government
within a country
• Geo-political issues
• Consistency in the degree of
implementation
15
28/09/2012
Harmonization of
Medical Device Regulations
• Harmonization is consistent with the
policies of many regulatory authorities
• Regulatory programs are expected to :
• use available international
standards/guidelines as basis for technical
regulations
• proactively influence their development, as
appropriate
• Consult with stakeholders/public
Overview
• GHTF(Global Harmonization Task Force)
• Informal grouping of medical device
regulators and industry
• Began in 1992 with Canada, European Union,
Japan, USA and Australia as founding
members
• Currently consists of a Steering Committee, 5
Study Groups and several Ad Hoc Groups
• Has links with several partners, including :
ISO, IEC, WHO, PAHO, AHWP
16
28/09/2012
Overview
• Working to reduce or eliminate technical
differences in regulatory requirements and
practices
• GHTF conferences and commenting on draft
guidance documents
• Participation is broadening
• “Participating members”
• “Observers”
Purpose
• To encourage convergence in regulatory
practices related to ensuring the safety,
effectiveness / performance, and quality of
medical devices, promoting technological
innovation and facilitating international trade
and
• To serve as an information exchange forum through
which countries with medical device regulatory
systems can benefit from the experience of other
members.
17
28/09/2012
Basic Principles
• Serves as an information exchange forum
• Countries with medical device regulatory
systems under development can benefit
from others’ experience
• May pattern their practices upon those of
GHTF founding members
• Avoid unnecessary (new) regulatory
requirements
• Wasteful for governments and industry
• Delays technologies to the patient bedside
