Always One Step Ahead –
Medical Product Testing

As an accredited and recognised test laboratory for medical products, we support manufacturers,
doctors and expert assessors in the field of certification testing, failure and damage analysis as well
as research and development for medical products.

Our main focus is, among others, in strength, resistance and wear tests of joint endoprosthesis, osteosynthesis products, trauma products, surgical instruments and skin adhesive and patch products in accordance with the standard or special test procedures.

At IMA Dresden, materials and models are extensively tested: artificial ageing, particulate measurement, strength calculations and damage analysis enhance the range of services.

Furthermore, we will be pleased to advise you on the required test series for your product on the way to approval. And one thing is for sure, should there not be a standardised test standard yet, then we will support you with the development of test requirements and specifications, based on scientific studies and databases.

Flexible accreditation from DAkks (German Accreditation Body) and recognition from ZLG (Central Body of the States for Health Protection) enables us to test materials and components according to different standards, as well as developing new testing procedures. The appendix to our accreditation certificate includes a comprehensive overview of the scope of validity for our accreditation.

Hip joint implants

The technical documentation for hip joint implants requires the verification of varied, different product characteristics on the basis of standardised test procedures. Our laboratory facilities make it possible for us to implement the tests in accordance with the relevant directives and guidelines. In the case of polyethylene components, we recommend a particle analysis (shape, size and number of wear particles).

Osteosynthesis implants / bone plates / bone screw / Intramedullary nails

Among other things, bone screws must resist defined torsional stress. The assessment of the flexural strength is of particular importance for bone plates. In there should be a case of failure, then a metallographic examination in our materialography laboratory is not only very instructive for this but also for all other implants.

Wound or tissue adhesives provide a painless alternative to wound closure using surgical sutures. The mechanical properties of the materials, and in particular the adhesive properties, are important parameters in evaluating their fitness for use. Prior to clinical use, these adhesive properties must be determined and the wound closure strength must be demonstrated. For the required tests we are accredited as laboratory according to guideline 93/42/ EWG and DIN EN ISO/IEC 17025.

materials and material combinations

In addition to the design, the utilisation of the suitable material and/or the suitable material combination is the basis for the long-term success after implantation. Material selection tests and analysis on material samples as well as finished implants ensure increased reliability for the patient application. Age is an ever increasing influence on the functional capability of the implants and is therefore of particular interest. We can provide you with artificial ageing in accordance with international standards. Our engineers will be pleased to provide you with more detailed information.

In the economic demands for shorter production development times and innovative and high-quality designs with better material efficiency and weight-optimized structures for optimal power flow.

We support you with the versatile simulation tasks, which are pending in the product development up to the virtual test bench. This challenge includes, for example, the simulation of contact situations, interference fit assembly, hyperelastic materials, plastics, and lifetime estimation of the structure. In addition, we identify worst case geometry variants (e.g. according to ASTM F2996, ASTM F3161-16) that lead to shortening of test times and cost reduction in the experimental evidence.

Our goal is the structural and cost optimization of your medical product already in the development stage.
