Claim:
1. A method of manufacturing a coated polytetrafluoroethylene tube, said method comprising: (a) applying a designated amount of a coating to an outer surface of a section of a body of the polytetrafluoroethylene tube, said section of the body of the polytetrafluoroethylene tube having a first outer diameter, said coating including: (i) a first pigment of a first color, and (ii) a binder; and (b) curing the applied coating to cause the coating to bond to the outer surface of the section of the body of the polytetrafluoroethylene tube to indicate at least one marking formed along the body of the polytetrafluoroethylene tube, wherein the curing causes the section of the body of the polytetrafluoroethylene tube to shrink such that after curing, the section of the body of the polytetrafluoroethylene tube has a second outer diameter less than the first outer diameter and the section of the body of the polytetrafluoroethylene tube with the cured coating has a third outer diameter approximately equal to the first outer diameter.
