Abstract
A catheter having a distal tip with an inner layer formed of a polymeric material having a coefficient of friction and surface energy which are relatively low, such that the inner layer has a lubricious, non-polar inner surface repulsive to polar liquids. As a result, blood coagulation in the distal tip, and adherence of the distal tip on the guidewire are prevented or minimized.
