Elastomeric coatings offer numerous functional benefits for implantable devices. The most obvious application is to create a blood impermeable barrier, which restricts blood flow to key locations. The barrier can also eliminate tissue adhesion to an implant, or contain material, such as thrombus, emboli or ureteral stone fragments, for example. Coatings can be extremely low profile and yet durable enough to be applied to almost any underlying implant surface, such as laser cut stents, braided devices or textiles. Aran Biomedical’s experience working with a diverse range of implantable elastomeric materials, such as silicones, polyurethanes and co-polymers, facilitates selection of appropriate material grades for an underlying application, taking into consideration mechanical properties such as: shore hardness, flexural modulus, ultimate tensile strength, tear resistance and ultimate elongation.
