Hydrophilic coatings have been in use for medical devices mainly as a means to improve maneuverability and reduce frictional forces between the devices and blood vessels. In specific, the adoption of these coatings in catheters, guide wires, and other intravascular medical devices has reached maturation globally. The various chemistries on which these coatings are based on include polyvinylpyrrolidone (PVP), polytetrafluoroethylene (PTFE), and silicone. Since the FDA warning at the end of 2015 regarding the risks associated with peeling, flaking, and delamination of widely used lubricious coatings, there has been a significant interest in identifying alternative solutions to improve bonding of flexibility of these coating when used in re-usable and disposable medical devices. In one account, there is a notification that since 2010, there has been 11 product recalls from device manufacturers due to flaking of coatings. In this issue, recent innovations and product upgrades, which have aimed to meet the un-met needs of the medical device industry, have been identified. An overview of the various technologies associated with new coatings are discussed with a strategic perspective of the impact that they can have in the short-term.
The Advanced Coating & Surface Technology TechVision Opportunity Engine (TOE) provides intelligence on technologies, products, processes, applications and strategic insights on various coatings across industries. This encompasses protective and functional coatings such as antimicrobial coatings, food coatings, energy-saving coatings, smart glazing, hydrophilic, hydrophobic and super hydrophobic coatings, corrosion protection coatings, barrier coatings and paints.
The Materials and Coatings cluster tracks research & innovation trends and developments across specialty chemicals, plastics, polymers, chemicals, bio-chemicals, metals, coatings, thin films, surface treatments, composites, alloys, oil and gas, fuel additives, fibers and several other related technologies and its impact and application across industries.
