North American Science Associates, LLC 2022. Due to the difficulty in obtaining a priori information on all the constituents in finished devices, information generation strategies in the form of analytical chemistry testing are often used. The Food and Drug Administration (FDA) partially recognized the ISO 10993 guidance making it one of the most important for the chemical characterization testing of medical devices.1 ISO 10993 outlines all of the necessary steps for regulatory compliance to use new or existing materials in medical devices. Thus, characterization studies are ultimately performed in order to gain a more complete understanding of a device, and of the risk factors associated with using a device.

Biological safety evaluations are designed to assess whether a product is safe for its intended use depending on its composition. As defined by FDA 21 CFR Part 820, where the results of a process cannot be fully verified by subsequent inspection and test, the process shall be validated with a high degree of assurance and approved according to established procedures. During the formulation and manufacturing of polymeric materials for medical devices, the materials go through multiple stages and undergo many transformations. It may also include chemical characterization testing for worst-case chemical release scenarios. Of utmost importance is to determine the critical chemistry components have not changed with modifications to the process. This role of chemistry as the central science is very important to medical device evaluations and is noticeably evident in the ISO 10993 approach to the biological safety evaluation of medical devices and biomaterials. TurbidityThis method is designed to measure the turbidity by comparing the intensity of light scattered by an aqueous sample with the intensity of light scattered by a standard reference suspension under the same conditions. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. https://namsa.com/services/medical-device-testing/. Melting PointThe melting point of a chemical is the temperature at which a substance changes physical state from a solid to a liquid at normal atmospheric pressure. This can be evaluated through a comprehensive chemical comparative study to investigate the extractable profiles and/or surface chemistries. For instance, ISO 10993-13, section 5.2 (regarding polymeric materials) states: The initial material characterization shall address the bulk polymer and the residuals and additives present in the final device. We also urge the industry as a whole to do the same: to start open discussions on these topics to help achieve a more consistent and harmonized approach to chemical characterization. With the complexity and extensive requirements for chemical characterization testing for medical devices, turn to an expert partner for help. EAG Laboratories: Material Characterization Experts.

Chemical characterization testing for worst-case chemical release may also include testing for situations where the device is biodegradable or polymerizable in-situ.

Website Design, Hosting and Maintenance by MVP Marketing + Design. Historically, assessing the safety(or biocompatibility) of a new medical device has been done primarily through in vivo biocompatibility testing. Extractables testing is one approach to chemical characterization that employs combinations of non-targeted analysis, non-targeted screening, and/or targeted analysis to establish the identities and quantities of the various chemical constituents that can be released from a device.

We hope to see working groups, on hiatus for the last two years, meet with renewed vigor and express perspectives not yet considered. It is important to fully characterize the purity of the polymer and the additives used in the formulation.. Others might see it as an important way to reduce risk or liability. To address, and hopefully alleviate some of this confusion, well be delving into material and chemical characterization what these terms mean, what the ISO standards say, what the FDA requirements are, and when certain types of testing are necessary. We strive to offer the most effective business practices while employing a staff of technical experts. Purified Water, USPUSP requirements for purified water include water conductivity and total organic carbon. Total SolidsTotal solids is the term applied to the material residue left in a vessel after evaporation of the sample and its subsequent drying in an oven at a specified temperature, usually between 103C and 105C. This also explains why the FDA is placing a greater emphasis on these studies to better ensure patient safety. An essential part of establishing biological safety is the implementation of chemical and material characterization testing. Because it is likely that the majority of material characterization data will be obtained from the manufacturer, subsequent posts will focus more specifically on chemical characterization, how this data can best complement in vivo biocompatibility data to inform on the overall toxicity profile of a medical device, and how this data can be used to assess the potential impact of manufacturing or materials changes. Abstract All rights reserved. The FDA tries to incorporate these risks into the proposed chemical characterization tests as part of ISO 10993 by insisting on different biological endpoint tests depending on where and how long a medical device will be used. ISO 10993-18 Medical Device Chemical Characterization and Extractables and Leachables for Biocompatibility of Materials. Uncompromising Integrity. When you have questions about your materials chemistry, EAG Laboratories provides comprehensive data for FDA submissions, innovation and product improvement.

Calcium ResidualThis method is used to determine the residual calcium of demineralized bone and other tissue-based products. With todays devices that include polymers and plastics, LC-MS is an analytical method that tends to yield more chemicals what means the laboratories must tap into their experts to make the identification; a significant resource commitment. As mentioned previously, a user of the device may be exposed locally and/or systemically to these chemicals, and it is important for the safety of the potential user to know whether use of the device may produce harmful effects. During the design of chemical characterization studies, NAMSA strives to recommend the most scientifically-supported approaches.

Changes in manufacturing processes of medical devices are inevitable. The developers of medical devices evaluate the biocompatibility of their device prior to the FDAs review and subsequent introduction to the market. A leachable study can be performed using conditions to mimic real use scenarios to determine the potential for identified chemistries to leach out of the product. Copyright 2012 Woodhead Publishing Limited. Fourier Transform Infrared (FTIR) ScanThis test is a type of infrared spectroscopy in which the sample is subjected to all the wavelengths in the region of interest at all times, instead of only a small portion at a time. On February 17, 2022, the American Chemical Society released a publication on behalf of the U.S. Food and Drug Administration (FDA) describing the current state and opinion of the FDA regarding chemical characterization processes and ways in which to improve them. In accordance with ISO 10993-1:2018, every medical device must be evaluated and tested as part of a risk management strategy; and Chemical Characterization is the starting point. Moisture Determination Karl FischerThe Karl Fischer reaction uses a coulometric titration to determine the amount of water in a sample. Dr. Cabovska holds a research degree in analytical chemistry and has over 10 years of experience in extractables and migration application. ConductivityConductivity is a physical test that measures the ability of an aqueous solution to carry an electric current. In particular, the FDAs response is intended to examine specific topics to promote continuous discussion regarding the disparities between where the industry currently stands and how alignment and proper development may occur.
