BDC Laboratories? SLIC? coating treatment for
Silicone-based anatomical models and mock vessels have long been
BDC Laboratories developed
To quantify the static and kinetic frictional forces, a sledbased test method derived from ASTM D1894 was utilized; whereby, a sled of known weight was pulled across the luminal surface of each test article while the associated force was continually measured.
Testing was performed on untreated silicone vessels, silicone vessels treated with BDC?s SLIC coating treatment and excised, wetted bovine aortas as a control. Multiple test runs were performed on each test article and the data averaged for analysis.
The use of silicone for manufacturing complex anatomical models and simple arterial/venous vessels is common and advantageous for its transparency, stability and durability. However, the inherent tackiness of the final product causes challenges in the models? use when tracking catheters, delivery systems and similar technologies.
A common manner to overcome this drawback has been to add a lubricating agent such as dish soap to the test solution; however, the presence of soap bubbles and other byproducts can present a problematic test environment. This is no longer required for silicone models manufactured by BDC Laboratories with their proprietary SLIC coating treatment.
BDC developed the SLIC treatment for their silicone anatomical models to significantly reduce the inherent friction of the luminal surface and result in a lubricity representative of in situ vessels. Therefore, the use of silicone models treated with BDC Laboratories? SLIC processes for bench testing and physician training will not require the addition of a lubricating agent to the test solution to present a clinically relevant environment. Moreover, BDC?s SLIC treatment will present comparable performance whether used in a wet or dry environment and maintain its performance for numerous
