ABSTRACT:
This invention is in the general field of surgical instruments. It relates specifically to catheters which may be used in cardiovascular and endovascular procedures to deliver diagnostic, therapeutic, or vaso-occlusive agents to a target site within a human or animal body which is accessible by a system of natural passageways within that body. The catheters are coated in such a way that they are exceptionally slippery and the coating is very durable. The invention also relates to methods of coating the catheters and to methods of applying lubricious coatings by forming a sheet of the coating on the substrate and simultaneously drying and crosslinking through heat and radiation.
