Abstract
This invention is in the general field of surgical instruments and, in particular, catheters. Specifically, it relates to procedures for coating the interior surfaces of surgical devices with a cross-linkable lubricious polymer, preferably one which is hydrophilic. These catheters may be variously used in cardiovascular and endovascular procedures to deliver diagnostic, therapeutic, or vaso-occlusive agents or devices to a target site within a human or animal body and to catheters used to guide other catheters to a particular site in that body. The interior of the catheters are coated using the noted procedure in such a way that the interior is exceptionally slippery and very durable.
