Résumé : |
Over the years, the use of coatings for medical devices and drug delivery has gone though a paradigm shift from being a rarity to being an absolute necessity. The latest generations of coatings have become indispensable in augmenting the capabilities of medical devices and implants. Without these coatings, many medical devices would never reach their true potential in the intended application. They impart a wide variety of properties such as lubricity, biocompatibility, and antimicrobial action to device surfaces. In addition to the above mentioned properties, coatings for medical devices are also being used extensively to carry out specific local drug release and make medical implants more visible to imaging systems. With the introduction ofdrug-eluting stents (DES), treatment of coronary artery disease has gone through a radical change, which resulted in improved success rates of a minimally-invasive surgery-an alternative to open heart surgery known as percutaneous transluminal coronary angioplasty (PTCA). DES, are basically mesh tubes coated with a slow release drug that helps to prevent coronary renarrowing of coronary artery after coronary angioplasty. As medicine moves further along the spectrum from invasive to non-invasive, device manufacturers increasingly demand slippery or lubricious coatings. Non-invasive procedures require slippery maneuverable catheters that physicians can move easily through small blood vessels or delicate tissue. With lubricious coatings on an increasing number of medical devices, surgeons can perform procedures that were impossible a decade ago. |
