Abstract
Disclosed here within is the method of manufacture of a reinforced and flexible tube or catheter that can be used in a variety of applications. The first method of embedding the metallic coil or braided wire comprises the steps of engaging the metallic structure over the outer surface of the tubular member, applying heat through an appropriately sized mold to the outer surface of the tubular member while creating a pressure differential between the inner lumen and the outside surface of the tubular member for a specified period of time. The second method of embedding the metallic coil or braided wire comprises the steps of engaging the metallic structure onto the outer surface of a mandrel, positioning the mandrel/metallic structure within the lumen of the tubular member, placing the tubular member within an appropriately sized mold, applying heat through the mold to the tubular member while creating a pressure differential between the inner lumen and the outside surface of the tubular member for a specified period of time.
