Aquarius® Direct-Coat Hydrophilic Coating utilizes a proprietary coating process to apply hydrophilic chemistry directly to the metal substrate of a device. Unlike products that require a polymer substrate for coating application, Aquarius® Hydrophillic Coating can be applied directly to existing stainless steel or nitinol designs to improve guidewire-to-catheter interface with low durometer, small french size catheters or crossing performance on interventional designs.
