Advancement in the design of medical devices such as catheters, guide wires and stents has improved the quality of medical care to great extent. However, these devices are made up of materials which when coming in contact with external environment can cause undesirable complications such as bacterial infection, blood clots and tissue trauma. Medical device coating is used to alleviate such short comings. Medical device coating technology uses organic solvent or UV curing for the purpose of coating the medical device. Dry or water-based formulations are used as coating technology which allows solvent-free processing.
Medical device coatings help in reducing the friction between medical devices and tissues, provide surface coverage, wetting, uniform adhesion, wear-resistance and coating homogeneity. Depending on the nature of formulation global medical device coating market can be bifurcated into dry lubricants coating, adhesive coating and super-hydrophilic coatings. Dry lubricants coating has the largest market share for medical device coating. However, super-hydrophilic coating is expected to witness highest growth in coming future owing to its increasing demand from medical devices that require excellent water attraction and optical clarity.
