    摘要: Embodiments of the invention include medical device elements formed from polymers with lubricious properties. In an embodiment, a method of forming a medical device element is included. The method can include mixing a first polymeric component and a second polymeric component to form a polymer mixture. The method can further include forming the polymer mixture into the medical device element. The method can also include treating the polymer mixture with at least one of an acid or a base. In an embodiment, a medical device is included. The medical device can include a lubricious element, the lubricious element comprising a mixture of a first polymeric component and a second polymeric component. The second polymeric component can include a polymer that is treated with at least one of an acid or a base after formation of the element. Other embodiments are also included herein.
