  4. 4. 4 Component Selection & Testing •Shape Memory Alloys (SMAs) are known for their large recoverable strains and are an ideal material for biomedical applications •Nitinol (NiTi), the most popular SMA, employed primarily for vascular stents, are studied extensively in tension •ASTM F2516 requires the materials to be loaded and unloaded in a cyclic test (as shown in the graph to the lower right) •Solutions: •Contacting or non-contacting extensometry to measure specimen strain (point to point) •Digital Image Correlation (DIC) to develop a full field strain map ASTM F2516 test method for NiTi in tension
  5. 5. 5 Component Selection & Testing •Radial compression and relaxation (crimping and uncrimping) of stents using RX fixture as an optional accessories on standard Instron® frames to simulate forces on stents during use RX fixture is an accessory on Instron frames
  6. 6. 6 Aortic Heart Valve Prototype Physiologic Testing A key factor for medical device success is biologic compatibility and physiologic function. Instron® bioreactor systems allow R&D teams to evaluate this criteria for new devices and replacement tissues on the bench before initiating expensive animal testing.
  7. 7. 7 •Fatigue testing (Simulate 10 years in vivo) •Tension •Compression •Torsion •Stent testing to match FEA Modeling •Tension, Torsion, Bending •Multiple Specimen Testing •Instron® actively involved in ASTM F04.30 committee •Fatigue systems that utilize linear electric technology (versus hydraulic oil) are the preferred solution for medical device labs: no oil, low noise, small footprint Final Product Durability Testing E10000 with 12-head accessory for durability testing of stents over millions of cycles
  8. 8. 8 Final Product Delivery Testing •Tortuous path represents vasculature •Usually glass or plastic fixture •Test stent deployment devices •Test friction of catheters (coatings) in a physiological environment •Machine can be used vertical or horizontal Tortuosity tester with custom grip control accessory to customize pressure (friction) at device opening
  9. 9. 9 3 Challenges in Biomedical QC Testing •Standards to follow and what others are doing in the market—what you test today may not be what you test tomorrow 1) Knowing How to Test •Best practices to ensure a highest level of product quality 2) Ensuring Quality of Results •Small investments to protect you for the future 3) Regulatory Compliance
  10. 10. 10 Knowing How to Test Standards to follow and what others are doing in the market—what you test today may not be what you test tomorrow 1
  11. 11. 11 Biomedical Applications: Orthopaedics Applications & Standards •Spinal Implants: ASTM F1717 •Intervertebral Discs: ASTM F2346 •Intervertebral Fusion: ASTM F2077 •Hip Replacements: ISO 7208 •Knee Replacements: ISO 14879 •Hip Screws: ASTM F384 Recommended solution for spinal implants testing Automated tuning wizard optimizes the system for a range of specimen stiffness. This allows for testing anything from hydrogels to bone on the same machine with optimal performance. Testing Tip
  12. 12. 12 Biomedical Applications: Dental •Dental implant fatigue to ISO 14801 •Fixture for testing endosseous dental implants •2-15 Hz depending on materials Testing Tip A 30º angle of the dental implant during testing is considered to simulate the “worse case” scenario of loading conditions.

See results from our demo lab:
  14. 14. 14 Biomedical Applications: Pharmaceuticals •Packaging: ASTM F88, ASTM D882, & ASTM D1894 •Caps for bottles, syringes, vials •Residual seal force Mean Max Load Testing Tip Testing packaging often requires a fast test and detection of quick events (e.g. first and average peaks). Setting the system data rate and bandwidth appropriately are important. Different Data Rate and Bandwidth Effect Results
  15. 15. 15 Biomedical Applications: Biomaterials •Biological Materials •Bone, tendons, ligaments, muscles, skin, etc. •Synthetic Materials to Mimic Biomaterials •Hydrogels, polymer scaffolds, etc. Tensile testing tissue with pneumatic grips Testing Tip Biomaterials are inherently slippery and difficult to grip. To get a better grip, without damaging the material, add friction. This can be done with surfalloy jaw faces or by simply using sandpaper between the grip faces. Also, using grips that can allow you to modify grip pressure, consistently (like a pneumatic style) can help significantly improve repeatability of results.
