Lubricious coatings for medical devices and their uses are described. The coatings can be synthetic and durable and lubricious. In some embodiments, the coatings can be ultra-violet (UV) cured. Lubricious coatings can reduce and/or minimize frictional forces between a medical device, such as a catheter or microcatheter, and a vessel wall, thereby enhancing trackability of the medical device throughout the vasculature.
A polyglycerol composition contains diglycerol, triglycerol, and tetraglycerol each in a content of 5 percent by weight or more, has a total content of diglycerol, triglycerol, and tetraglycerol of 75 percent by weight or more, has a total content of higher polyglycerol components of 10 percent by weight or less, the higher polyglycerol components each having a degree of polymerization of 7 or higher, and is substantially free from chlorine atom. A process prepares a polyglycerol composition by reacting glycerol and/or a polyglycerol with glycidol in the presence of an activated carbon catalyst.
