Abstract
A plastic medical article, such as a catheter or blood collection tube, is coated with a crosslinked hydrogel permanently bound to the inside wall of the tube. The hydrophilic surface provided by the hydrogel prevents adherence of blood components to the surface, and the permanent adherence of the hydrogel prevents its removal by blood.
