Reprocessing Validation for Reusable Medical Devices
Ensure the safety of your reusable medical devices. We validate your Instructions for Use (IFU) to prove that your cleaning, disinfection, and sterilization protocols are effective and regulatory-compliant.
For reusable medical devices, the manufacturer is responsible for providing the Instructions for Use (IFU) – either finalized or in draft form – which we then validate through rigorous analysis to ensure the device can be safely reprocessed between patients. Reprocessing validation is a critical regulatory requirement under ISO 17664 and FDA Guidance, ensuring that every trace of biological soil and microbial life is removed or destroyed. At EBI, we provide the technical data required to guarantee patient safety throughout the device’s lifecycle.
Cleaning Validation (Manual & Automated)
Objective: To verify that clinical soil can be effectively removed from the device.
Cleaning is the most important step in reprocessing; if a device is not clean, it cannot be effectively disinfected or sterilized. We validate both Manual (hand-washing/ultrasonic) and Automated (washer-disinfector) protocols.
- Methodology: We „stress” the device by soiling it with a standardized test soil (simulating blood, proteins, and lipids). We then follow your IFU precisely to clean the device.
- Residual Analysis: We perform exhaustive recovery to quantify remaining contaminants, including Protein and Hemoglobin.
- Compliance: ANSI/AAMI ST98 (formerly TIR30), ISO 15883, and ASTM 2314.
- Sample Requirements: At least 5 samples.
Disinfection Validation
Objective: To demonstrate a specific log-reduction of microorganisms when sterilization is not possible.
Disinfection is required for „semi-critical” devices that cannot withstand high-heat sterilization. We validate three levels of disinfection based on the device’s intended use (Spaulding Classification):
- High-Level Disinfection (HLD): Targets all vegetative microorganisms and a 6-log10 reduction of Mycobacterium spp.
- Intermediate-Level Disinfection: Targets a 6-log10 reduction of vegetative bacteria (e.g., S. aureus, P. aeruginosa) and a 3-log10 reduction of Mycobacterium spp.
- Low-Level Disinfection: Targets a 6-log10 reduction of standard vegetative bacteria.
- Compliance: AAMI TIR12, ISO 15883, and FDA Reprocessing Guidance.
- Sample Requirements: At least 7 samples.
Steam Sterilization Validation
Objective: To confirm a Sterility Assurance Level (SAL) of $10^{-6}$ using heat and pressure.
The goal of this study is to validate the specific sterilization parameters (time, temperature, drying time) described in your IFU. This ensures that healthcare facilities can achieve total sterility every time.
- Methodology: We challenge the most difficult-to-reach areas of the device with a suspension of highly resistant bacterial spores (Geobacillus stearothermophilus) or calibrated Biological Indicators (BI).
- Modalities: We specialize in Steam/Heat (Autoclave) and Ethylene Oxide (EO) validations.
- Compliance: ISO 17665 (Steam), ISO 11135 (EO), and AAMI ST79.
- Sample Requirements: At least 5 samples.
Why Reprocessing Validation is Critical
- FDA & MDR Compliance: Regulators require rigorous evidence that a device can be reprocessed without degrading or harboring pathogens.
- IFU Reliability: We ensure your instructions are clear, practical, and effective for hospital staff.
- Liability & Safety: Validated protocols minimize the risk of healthcare-associated infections (HAIs) and cross-contamination.

FAQ: Frequently Asked Questions
What is „Test Soil” in cleaning validation?
Test soil is a specialized mixture of proteins, carbohydrates, and fats designed to mimic the most difficult clinical contaminants found on a device after surgery.
Why is visual inspection not enough?
While visual inspection is a part of the process, it cannot detect microscopic protein residues or bacterial endotoxins. In washing validation studies, visual assessment of cycle effectiveness is only possible if the material being tested has been classified as ‘non-critical’. Quantitative analysis (like TOC or Protein assays) is required to prove a device is truly „clean.”
Does a change in device material require a new validation?
Often, yes. New materials may have different „stickiness” for soils or different heat-transfer properties during sterilization, which could impact the effectiveness of your existing IFU.
