75 Santiago de Chile, May 9 – 12, 2006 STED Risk analysis 7.5 Risk analysis The STED should summarize or reference or contain (as determined by need for a submission and the option selected by the manufacturer in Section 6.2) the results of the risk analysis. This risk analysis should be based upon international or other recognized standards, and be appropriate to the complexity and risk class of the device.

76 Santiago de Chile, May 9 – 12, 2006 STED Risk analysis Can you have full Risk Analysis (or Risk Management) details in STED ???

77 Santiago de Chile, May 9 – 12, 2006 STED Risk analysis Risk analysis/mgt dossier is BIG No prescribed format Links to many other documents Decisions made by manufacturer (How to) interpret all information?

78 Santiago de Chile, May 9 – 12, 2006 STED Risk analysis For the manufacturer Include process description in STED dossier Give actual RM process data for the device For the regulator Verify that RM process IS in place

79 Santiago de Chile, May 9 – 12, 2006 STED Risk analysis For the manufacturer Include process description in STED dossier Give actual RM process data for the device For the regulator Verify that RM process IS in place

80 Santiago de Chile, May 9 – 12, 2006 STED Summary documents of pre-clinical design verification and validation 7.3.1 General on design V&V declarations/certificates of conformity to the “recognized” standards listed as applied by the manufacturer and/or … summaries or reports of tests and evaluations based on other standards, manufacturer methods and tests, or alternative ways of demonstrating compliance

81 Santiago de Chile, May 9 – 12, 2006 STED engineering tests laboratory tests biocompatibility tests animal tests simulated use software validation Summary documents of pre-clinical design verification and validation

82 Santiago de Chile, May 9 – 12, 2006 STED 7.3.2 Clinical Evidence The STED should indicate how any applicable requirements of the Essential Principles for clinical evaluation of the device have been met. Where applicable, this evaluation may take the form of a systematic review of existing bibliography, clinical experience with the same or similar devices, or by clinical investigation Summary documents of (pre-)clinical design verification and validation

83 Santiago de Chile, May 9 – 12, 2006 STED Manufacturing information 7.6 Manufacturer information The STED should summarize or reference or contain documentation related to the manufacturing processes, including quality assurance measures, which is appropriate to the complexity and risk class of the device

84 Santiago de Chile, May 9 – 12, 2006 STED From 2.0: Regional tailoring As an interim measure until full global harmonization of documentation requirements is achieved, the precise content of the STED … will need to be augmented by documentation required by country-specific regulations and regulatory guidance USA - FDA / Canada - HC / Europe - NB’s / Australia - TGA / Japan - MHLW / other - ? Regional tailoring

85 Santiago de Chile, May 9 – 12, 2006 STED USA - FDA / Canada - HC / Europe - NB’s / Australia - TGA / Japan - MHLW / other - ?

87 Santiago de Chile, May 9 – 12, 2006 STED

88 Santiago de Chile, May 9 – 12, 2006 STED USA - FDA / Canada - HC / Europe - NB’s / Australia - TGA / Japan - MHLW / other - ? Regulators and industry should jointly evaluate progress towards harmonization and adapt processes accordingly: “continual improvement” Regional tailoring

89 Santiago de Chile, May 9 – 12, 2006 STED

90 Santiago de Chile, May 9 – 12, 2006 Building blocks for harmonized regulatory processes International Standards

91 Santiago de Chile, May 9 – 12, 2006 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

92 Santiago de Chile, May 9 – 12, 2006 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

93 Santiago de Chile, May 9 – 12, 2006 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 !!

94 Santiago de Chile, May 9 – 12, 2006 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

95 Santiago de Chile, May 9 – 12, 2006 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

96 Santiago de Chile, May 9 – 12, 2006 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

97 Santiago de Chile, May 9 – 12, 2006 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 …
