Abstract
A plastic catheter and a method for making the same, the catheter having radiopaque marker ring placed within a tube, whereby the radiopaque ring is inserted into the expanded section of the tube, followed by the relaxation of the tube to its original dimensions, such that there is no protusion of the ring on the tube inner-diameter, where the ring inner-diameter is equal or greater than the tube inner-diameter, and the ring outer-diameter protrudes a distance into the tube but not beyond the thickness of the tube; thereby, creating a smooth outer surface and an obstruction free inner surface.
