Antimicrobial, fluoropolymer, hydrophilic, and anodic coatings are some of the popular coatings. Medical Device Manufacturers (MDMs) are also employing Physical Vapor Deposition (PVD) to create long-lasting, serviceable coatings for surgical instruments, dental implants, knee replacements, and other specialty items.

FREMONT, CA: There is a rise in the demand for complex medical devices, particularly for implants and minimally invasive and robotic surgical procedures. With this growth, there is also an augmented demand for high-performance, biocompatible specialty coatings that meet the engineering, clinical, and operational (cost, quality, delivery) needs for these devices.

Medical coatings range from antimicrobials to lubrications to water-repellent polymers and can be tailored to the kind of application or device to enhance patient outcomes. They can also perk up the efficiency of the equipment and extend their functional life.

Despite the type of coating needed, surface preparation is always required for creating a strong bond with the substrate (characteristics can be as small as 20-50 nm). Manufacturers persist in extending more inclusive specifications and new processes for producing dependable surfaces before coating.

Latest Trends

A more considerable assortment of coating materials, with highly detailed engineered properties, is being developed to meet the multifunctionality of superior medical devices. Sometimes different coatings are even needed for diverse surfaces on the same device. Contemporary substrate materials are being deployed in innovative ways, comprising nitinol, cast aluminum, titanium, and polyetheretherketone (PEEK). Besides, Additive Manufacturing (AM) creates new material textures and structures that dare the efficacy of conventional coating methods.

Hydrophilic coatings are in high demand, in particular, for lower-cost medical devices. According to research, cardiovascular devices accounted for the leading share of the coatings market in 2015—about 35 percent. This part is expected to rise at a Compound Annual Growth (CAGR) rate of 3.22 percent from 2016 to 2021. Orthopedics was the second-largest application market capturing 21.84 percent volume share, increasing at a slightly faster pace of five percent.
