Surmodics Launches Preside Medical Device Coating Technology

November 7, 2023—Surmodics, Inc. recently announced the commercial launch of its Preside hydrophilic medical device coating technology. Preside hydrophilic coatings are formulated to balance enhanced lubricity and coating durability for the next-generation neurovascular, coronary, and peripheral vascular devices.

According to the company, Preside complements Surmodics’ existing Serene hydrophilic coatings by providing a low-friction and low-particulate generation coating to enhance distal access for neurovascular applications, as well as improve crossing for challenging coronary lesions or chronic total occlusions.

Preside’s improved particulate reduction also addresses increasing regulatory requirements. Additionally, Preside hydrophilic coatings allow customers to leverage their existing coating processes resulting in easy implementation in a manufacturing environment.

Surmodics stated that Preside hydrophilic coatings bond to a wide variety of substrates present in market-leading neurovascular, coronary, and peripheral catheters.

Preside hydrophilic coatings are applied using Surmodics’ Photolink ultraviolet (UV) curing process, which covalently bonds surface treatments to substrates at ambient temperature. This flexible technology can easily be incorporated into existing manufacturing processes and can markedly reduce production time and reagent costs compared to both thermal-curing and alternative UV-based chemistries and processes, stated Surmodics.
