Therefore, medical devices are assigned to different categories dependent on the kind of contact and the contact time to the human body. Guidance for Industry and Food and Drug Administration Staff, Issued on June 16, 2016. Ideally, testing should be performed according to the standards recognized by the applicable regulatory bodies. For example, a change in the roughness of a surface change of morphology may directly influence the cytotoxicity of the material whereas a chemically safe material with rough edges or particulates that can physically harm patient causing irritation. Make checks payable to MetricStream Inc.
The test strategy should also take into account where the device will be submitted for registration and marketed, e. This can be done with testing or a documented justification. Information such as existing data, additional endpoint-specific testing, or rationales can be used. We apologize for any inconvenience this may have caused. Based upon the categorization of the device under evaluation, the manufacturer should develop an appropriate testing strategy. This standard is also available to be included in Standards Subscriptions.
For example, a pacemaker may include both a pulse generator that is implanted subcutaneously and leads that are implanted within the cardiovasculature. The biological safety of various categories of possible toxicological effects should be considered for a particular device. The manufacturer should consider if data are available which cover the marked biological effects. Any use, including reproduction requires our written permission. It is critical to understand this guidance when commercializing a medical device. No-shows will be charged the full amount.
For these materials, it is sufficient to show that removal of process related surface residues at the end of the manufacturing process has been performed. He has over 20 years of experience in the pre-clinical evaluation of medical devices for biological safety. This seminar will discuss the recent changes to regulatory documents and standards and how they will impact the overall biocompatibility assessment of medical devices. Special consideration should be paid to Attachment A of the guidance document which provides a framework for the development of a biocompatibility testing plan. Manufacturers are required to weigh risks and benefits of a device. After it is determined which biological effects are relevant and should be considered, the safety risk of each of these effects needs to be addressed. All device types all device categories, with all types of contact, and all durations of contact will require a chemical characterisation as a prerequisite for the risk assessment.

In case it is not available, we will send the material after the conference is over. Please first with a verified email before subscribing to alerts. .
Medical devices can be divided into different categories. If the document is revised or amended, you will be notified by email. Learn how to achieve more successful biocompatibility testing outcomes by attending this seminar. An additional alternative to testing is to use raw materials that are known to be biocompatible and have a long history of safe-use as a medical device material, i. It has a central location right in the heart of Copley Square, facing the Trinity Church, easily accessible by taking the Green Line to Copley station or also near to Orange Line Back Bay stop.
Please bring the pass to the venue of the event. To document these conclusions, the marketed device materials should be listed and the method of establishing equivalence identified i. Medical devices are an important tool in efforts to improve patient care and treatment outcomes. In order to completely evaluate the biological safety of a medical device, the nature and duration of body contact must be considered. The approach to biocompatibility is changing, moving towards an evaluation based upon review of relevant established scientific data, physico-chemical characterisation and in vitro testing, with in vivo testing only being carried out to fill gaps in our understanding. New materials used in a device might require additional evaluations beyond those mentioned in Attachment A, and devices with multiple types of exposure should include information to address each exposure category.
All copyright requests should be addressed to. However, when the device polymerizes in-situ or is biodegradable, the interim reaction and degradation products must also be investigated for potential biological risk. Also, before starting in vivo tests results of in vitro tests should be available. The following part s of the standard is are not recognized Clause 5. Subscription pricing is determined by: the specific standard s or collections of standards, the number of locations accessing the standards, and the number of employees that need access.
Some topics and speakers may be subject to change without notice. Understand what tests to select and how to choose among various options. Based on the contact and the contact time in the human body, the necessary tests can be determined for the biological evaluation of the medical product. The evaluation of possible interactions and potential secondary effects of medical devices in contact with the human body is required by the regulatory authorities.

Testing of Medical Devices Medical devices that come into contact with the human body are required by the regulatory authorities to be tested on possible interactions and potential unwanted side effects.
