Abstract
A medical device including a plasma-treated porous substrate that is functionalized to provide a hydrophilic surface, and a process for preparing such a medical device, are disclosed. The method includes plasma treating at least a portion of a surface of a porous substrate with a gas species selected from oxygen, nitrogen, argon, and combination thereof. The gas species is configured to functionalize the surface of the medical device and form a hydrophilic surface.
