Tensile Testing of Soft Biological Tissues

With continued growth in the biomaterials market, characterization of the mechanical properties of soft tissues has become a rising interest. These properties allow for the understanding of tissue function and injury mechanisms, aiding engineers and researchers in the development of bio-engineered tissues, computer assisted and remote robotic surgical methods, and injury prevention recommendations. One of the challenges in testing soft tissues arises in gripping of the specimens. Biological tissues are often times wet, slippery or delicate. Any combination of these characteristics leaves the existing test methods far below the ideal gripping solution. The ultimate goal lies in the fixation of soft biological tissues without causing premature failure or slippage.

Tensile Testing of Hydrogels In a Temperature-Controlled Bath

Hydrogels are widely used in the biomedical industry for applications such as coatings for catheters, contact lenses, scaffolds, and wound dressings because these materials have the ability to absorb fluids and swell up to 2000 times their original size. Hydrogels are often implanted into the body to provide medical benefits and therefore

Advanced Video Extensometer (AVE) Marking Techniques for Soft Tissue Testing

Extensometers are often used to accurately measure the deformation of a material under mechanical loading. Due to the fragile nature of biological soft tissues, such as fascia, skin, and intestinal lining, a non-contacting extensometer is the ideal solution for measuring tensile strain in these specimens.

Testing of Medical Adhesives using a Variable Angle Peel Fixture

Medical adhesives are widely used in the biomedical industry for applications such as bandages, secondary dressings, and wound closure. The adhesive strength of these products must be clearly defined before put to use in a clinical setting. If the adhesive is not strong enough, the product may lead to infection or poor healing. If the adhesive is too strong, the underlying tissue may become damaged upon removal.

Mechanical Testing of Medical Implants

Implants and the materials used for their production undergo extensive tests, which include the evaluation of the static and dynamic mechanical properties of the raw materials, components and systems. Many of these tests are internationally standardized, other testing proceduresare specific to a given application.
