Any object put inside the human body brings risks with it, but recent technological advances in the coating have proved to be as essential as the medical devices they cover.
FREMONT, CA:Medical device manufacturers should contend with several challenges to differentiate products in today's competitive market, placing a greater focus on functional coatings applied to medical devices like implants. This makes it clear that the performance of medical devices is critical because an object put inside a human body brings many risks with it. The coatings applied to these devices to reduce potential health risks, guard the body, or enhance the body's acceptance of an outside object is as important as the device's design itself. With this comes an increased demand for high-performance, biocompatible speciality coatings that match with the clinical, engineering, and operational demands for these devices. Read on to know more.
Surface treatment methods and techniques are continually evolving to keep up with enhancements to existing substrates and newly developed substrates and polymers. A vast selection of coating materials with specific engineered properties is being created to meet advanced medical devices' multifunctionality. Sometimes multiple coatings are needed for different surfaces on the same device. Existing substrate materials are being harnessed in innovative ways, such as nitinol, titanium, cast aluminum, and polyetheretherketone. Additionally, additive manufacturing creates new material structures and textures that challenge the effectiveness of conventional coating methods.
There is also emerging emphasis on surface texturing of medical devices on the nanoscale to improve tissue attachment and growth and inhibit bacterial colonization. There is also a noticeable progression of minimally invasive and robotic procedures in insulative and abrasion-resistant coatings. Well-established, off-the-shelf coatings and materials are selected because they are low risk and have an established cost. However, expensive proprietary coating formulas specific to a single medical device or application are often needed for medical devices.
As medical devices become smaller and more complex and use advanced materials, the need for specialized coatings and advanced surface treatments will grow. This, combined with continuing improvements in material advancements, will continue to create growth opportunities and market demand for an increasing number of coating options.
