Presentation overview

• Introduction

• Purpose

• Overview of main points of Essential Principles guidance document



http://www.ghtf.org/index.html



Document history

“The GHTF has identified as a priority the need to harmonize essential safety and performance criteria for a medical device that allow the manufacturer to demonstrate its product is suitable for its intended use.

This goal was achieved through the publication of guidance on the subject entitled Essential Principles of Safety and Performance of Medical Devices (SG1/N020 of June 30, 1999) that applied to the majority of medical devices but not to in vitro diagnostic devices. …”



Document history

“…. This current document supersedes that earlier one. The major difference between them is the expanded scope; this document now includes medical devices for the in vitro examination of specimens derived from the human body.”



Rationale

“Consistent identification, selection and application of safety and performance principles to a medical device offers significant benefits to the manufacturer, user, patient or consumer, and to Regulatory Authorities since it allows its manufacturer to design, manufacture and demonstrate the device is suitable for its intended use. ...”



Rationale

“… Moreover, eliminating differences between jurisdictions decreases the cost of gaining regulatory compliance and allows patients earlier access to new technologies and treatments.”



Scope

“This document applies to all products that fall within the definition of a medical device that appears within the GHTF document Information Document Concerning the Definition of the Term “Medical Device”, including those used for the in vitro examination of specimens derived from the human body.”

Purpose

“To describe six general requirements of safety and performance that apply to all medical devices.

To provide a comprehensive list of design and manufacturing requirements of safety and performance, some of which are relevant to each medical device. …” [emphasis in original]



Purpose

“… These are grouped as:

• Chemical, physical and biological properties

• Infection and microbial contamination

• Manufacturing and environmental properties

• Devices with a diagnostic or measuring function

• Protection against radiation

• Requirements for medical devices connected to or equipped with an energy source

• Protection against mechanical risks …



Purpose

“… These are grouped as: (continued)

• Protection against the risks posed to the patient by supplied energy or substances

• Protection against the risks posed to the patient for devices for self-testing or self-administration

• Information supplied by the manufacturer

• Performance evaluation including, where appropriate, clinical evaluation”



Purpose

“The manufacturer selects which of the design and manufacturing requirements are relevant to a particular medical device, documenting the reasons for excluding the others.

The Regulatory Authority and/or Conformity Assessment Body may verify this decision during the conformity assessment process.” (or audit)

General requirement 1

“Medical devices should be designed and manufactured in such a way that, when used under the conditions and for the purposes intended and, where applicable, by virtue of the technical knowledge, experience, education or training of intended users, they will not compromise the clinical condition or the safety of patients, or the safety and health of users or, where applicable, other persons, …”



General requirement 1 (continued)

“… provided that any risks which may be associated with their use constitute acceptable risks when weighed against the benefits to the patient and are compatible with a high level of protection of health and safety.”




“The solutions adopted by the manufacturer for the design and manufacture of the devices should conform to safety principles, taking account of the generally acknowledged state of the art.

When risk reduction is required, the manufacturer should control the risk(s) so that the residual risk(s) associated with each hazard is judged acceptable. …”

Reference: ISO 14971:2001: Medical devices – Application of risk management to medical devices



General requirement 2 (continued)

“The manufacturer should apply the following principles in the priority order listed:

• identify known or foreseeable hazards and estimate the associated risks arising from the intended use and foreseeable misuse,

• eliminate risks as far as reasonably practicable through inherently safe design and manufacture

• reduce as far as is reasonably practicable the remaining risks by taking adequate protection measures, including alarms,

• inform users of any residual risks”




“Devices should achieve the performance intended by the manufacturer and be designed, manufactured and packaged in such a way that they are suitable for one or more of the functions within the scope of the definition of a medical device applicable in each jurisdiction.”




“The characteristics and performances …. should not be adversely affected to such a degree that the health or safety of the patient or the user and, where applicable, of other persons are compromised during the lifetime of the device, as indicated by the manufacturer, when the device is subjected to the stresses which can occur during normal conditions of use and has been properly maintained in accordance with the manufacturer’s instructions.”




“The devices should be designed, manufactured and packed in such a way that their characteristics and performances during their intended use will not be adversely affected under transport and storage conditions (for example, fluctuations of temperature and humidity) taking account of the instructions and information provided by the manufacturer.”




“The benefits must be determined to outweigh any undesirable side effects for the performances intended”



Conformity assessment

“Refer to … Principles of Conformity Assessment for Medical Devices and the work of GHTF Study Group 5 for further information on the use of clinical evaluation to demonstrate compliance with these Essential Principles.”



Summary

• Essential Principles form foundation of harmonised global regulatory model

• Comprehensive in scope

• Cover safety and performance

• Define design requirements

• Do not define methods of achieving, demonstrating, or documenting conformity

• Often covered by international standards



Summary

• Flexible to accommodate advances in the state of the art and new medical devices / technologies / intended uses

• Recognise risks and benefits associated with medical devices

• Are founded on risk management principles

• Intimately linked to manufacturer’s quality system for design, manufacture, and risk management

STED



Regulators and industry should jointly evaluate

progress towards harmonization and

adapt processes accordingly:

“continual improvement”

Regional tailoring


STED


Building blocks for harmonized regulatory processes

International Standards


Use of Standards in conformity assessment(another GHTF SG1 document)

• Compliance to “Recognized Standard” gives• “Presumption of compliance” with Essential

Principles• Voluntary except when deemed mandatory• Manufacturer is free to select alternative

solutions to demonstrate compliance– National and International standards– Industry standards– Internal SOP– Current state of art techniques related to

performance, material, design, processes


Standards in STED

• In STED, in lieu of technical doc. submission• Declarations, certificates, summary test

report• Retain documentation to demonstrate

device compliance to selected standard or other means to meet Essential Principles– How standard was applied with test results.– Deviations

• other means to compliance• when not applicable


Standards in development

• ISO, IEC, … are global bodies• Use defined consensus mechanism• All stakeholders involved• Stepwise development process:

NWIP / CD / CDV or DIS / FDIS / IS• Maturation process, usually > 3 years• Voting process includes national

committees• Great help in global convergence !!


Standards in development

A few well known examples:

• ISO 13485: Quality Mgt. System for medical device manufacturers

• ISO 14971: Risk Mgt. for medical devices

• IEC 60601-1: Safety & Essential Performance for medical electrical equipment


Revision or Replacement of Recognized Standards

• Updated standard becomes “recognized” too• Transition Period

– Should allow for manufactures to implement– Max < 5 years; unless exceptional circumstances

• During Transition Period– Both versions give presumption of conformity to EP– Unless safety implication, devices on market is OK

• After Transition Period– Superseded document may be withdrawn– Manufacturer using superseded version may do so

but should perform & document risk assessment on differences


Summary on standards

• Standards compliance is one means to demonstrate compliance to Essential Principles

• Transition to revised version important• Standards enforcement flexibility should be

allowed• International standards key in harmonization• Economies may want better participation in

development and use of international standards


STED

Final comments STED is a compilation of a subset of

documents normally generated during the design process

Size of the STED dossier is proportional to the risk class of the device

Some regional tailoring is still here …
