Biological evaluation plan (BEP)

ISO 10993-1
A biological evaluation plan (BEP) is a critical part of assessing the safety of a medical device. It involves a detailed examination of various aspects such as the device's design & structure, its material composition, manufacturing process & potential contaminants, the intended use, existing test results, and clinical history. The BEP ensures that the device undergoes sufficient biocompatibility testing, with parameters selected from the ISO 10993-1 standard. As a manufacturer, you will need to have a BEP during the regulatory approval process to demonstrate the safety of your medical device. The BEP should be developed during the initial design phase of the medical device. At this stage, manufacturers can identify potential biological risks associated with the device's intended use, materials, and components. A new BEP or updates to the existing one may also be needed if changes are made to the device's design or material composition at a later point. At Measurlabs, we can provide a BEP for a range of medical devices while also guiding manufacturers throughout the process. Do not hesitate to contact us if you are developing a new device, seeking regulatory approval, making changes to an existing product, conducting post-market surveillance, or performing preclinical testing.  We are also happy to create an offer for biocompatibility testing according to the BEP, as well as a biological evaluation report (BER) to summarize the results of the biological evaluation.

Ethylene oxide (EO) sterilization and sterilization residues by ISO 10993-7

ISO 10993-7
Sterilization residue testing according to ISO 10993-7 is a crucial part of the biocompatibility assessment for medical devices that have been sterilized with ethylene oxide. During the assessment, harmful compounds originating from ethylene oxide sterilization are analyzed to ensure that the device is safe to use after sterilization. Testing is required for the regulatory approval of applicable new medical devices in the EU (under the MDR) and the US (510(k) submission to the FDA). Ethylene oxide sterilization can be used when steam sterilization is not appropriate for the device. Ethylene oxide (EO) and ethylene chlorohydrin (ECH) are irritating and toxic chemicals, and for this reason, it has to be ensured that residue levels cause minimal risk to the patient during normal product use. ISO 10993-7 sets the maximum daily doses for EO and ECH in mg/d, based on the device's exposure duration category (limited, prolonged, or permanent). Residual amounts shall not exceed these maximums. During the assessment, the product is extracted with water and the amount of ethylene oxide and ethylene chlorohydrin is determined chromatographically. Extractions are made until the cumulative exposure does not increase. The displayed example price covers both ethylene oxide sterilization and analysis of sterilization residues (EO and ECH). Price includes a 6-hour sterilization cycle for one euro pallet (80x120x190cm) with 3 extractions. Please ask for a quote for your medical device.

Accelerated aging of medical device sterile barrier systems by ASTM F1980

ASTM F1980
ASTM F1980 establishes a standardized approach for accelerated aging of medical device sterile barrier systems (SBS), either with or without devices. Accelerated aging studies help manufacturers assess the shelf life of the product more rapidly than real-time aging studies. The results may be used as a preliminary indication of a product’s stability and packaging integrity until real-time aging results become available. This approach aligns with regulatory expectations, including FDA guidance (21 CFR - Process Validation) and ISO 11607-1. In accelerated aging studies, materials are exposed to elevated temperatures for a shorter period, simulating the effects of real-time aging. Based on the results, manufacturers can estimate how long the packaging will maintain its protective properties under real-world storage and transportation conditions. Product stability can be evaluated both upon completion and throughout the aging process using various methods. The assessed properties are selected based on the manufacturer’s specific requirements and regulatory considerations, and they may include the following: Sterility, Mechanical performance (e.g. shear, tensile, and compression strength), Chemical properties (e.g. product degradation). Measurlabs can provide accelerated and real-time aging in parallel. We can also help with stability and integrity testing during and after the aging period.

Systemic toxicity studies for medical devices by ISO 10993-11

As part of a medical device's biocompatibility evaluation, systemic toxicity tests following ISO 10993-11 assess the risk of the device or its components causing harmful effects throughout the body. Systemic toxicity refers to effects that may be observed when the device or its particles enter the body and affect multiple organs or systems, rather than a specific contact site. Systemic toxicity can be evaluated through studies of: Acute systemic toxicity (exposure up to 24 hours), Subacute systemic toxicity (exposure >24 hours up to 28 days), Subchronic systemic toxicity (exposure for part of the lifespan), Chronic systemic toxicity (exposure for a major part of the lifespan). The most appropriate study type depends on factors like administration route, exposure time, and frequency, which should be justified according to the device's intended use. All the tests are typically in vivo animal studies, and samples should be prepared following ISO 10993-12. Implantation studies may be combined with systemic toxicity testing, ask more about the possibilities from our expert. In toxicity studies, the tested device or its extract is administered or injected into the animal via the most clinically relevant route (dermal, implantation, inhalation, intradermal, intramuscular, intraperitoneal, intravenous, oral, or subcutaneous administration). Exposed animals are then evaluated through clinical pathology, histopathology, and/or gross pathology. Acute systemic toxicity tests assess the effects of single, multiple, or continuous exposures up to 24 hours and are often conducted on rodents (mice, rats)., Subacute, subchronic, and chronic systemic toxicity are relevant when the device is expected to be in contact with the body for prolonged periods, and testing is typically conducted on rats or rabbits..
