A method of manufacturing a coated low-friction medical device, such as low-friction medical tubing, including applying a coating to one or more selected portions of a surface of low-friction medical tubing to indicate at least one marking formed along the surface of the low-friction medical tubing,
A method of manufacturing a coated low-friction medical device, such as low-friction medical tubing, including applying a coating to one or more selected portions of a surface of low-friction medical tubing to indicate at least one marking formed along the surface of the low-friction medical tubing, and simultaneously or substantially simultaneously: (a) curing the applied coating to a designated temperature (which is above the temperature at which the low-friction medical tubing begins to decompose and shrink) to adhere the applied coating to the surface of the low-friction medical tubing, (b) utilizing one or more anti-shrinking devices to counteract or otherwise inhibit the shrinking of the low-friction medical tubing, and (c) exhausting any harmful byproducts resulting from curing the low-friction medical tubing to a temperate above the temperature at which the low-friction medical tubing begins to decompose.

1. A method of manufacturing a coated shrinkable tube, said method comprising: (a) applying a designated amount of a coating to an outer surface of a section of a body of the shrinkable tube, said section of the body of the shrinkable tube having a first outer diameter, said coating including: (i) a
1. A method of manufacturing a coated shrinkable tube, said method comprising: (a) applying a designated amount of a coating to an outer surface of a section of a body of the shrinkable tube, said section of the body of the shrinkable 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 shrinkable tube to indicate at least one marking formed along the body of the shrinkable tube, wherein the curing causes the section of the body of the shrinkable tube to shrink such that after curing, the section of the body of the shrinkable tube has a second outer diameter less than the first outer diameter and the section of the body of the shrinkable tube with the cured coating has a third outer diameter approximately equal to the first outer diameter. 2. The method of claim 1, wherein the binder is selected from the group consisting of: an epoxy, a phenolic, a phenoxy, a polyimide, a polyamide, a polyamide-amide, a polyphenylene sulfide, a polyarylsulfone, polyethylene, a polytetrafluoroethylene, a fluorinated ethylene propylene, a perfluoroalkoxy, tetrafluoroethylene-hexafluoropropylene, a polyetheretherketone, a polyetherketone, and a tetrafluoroethylene perfluoromethyl vinyl ether copolymer. 3. The method of claim 1, wherein the shrinkable tube is selected from the group consisting of: a solid polytetrafluoroethylene tube, a non-solid polytetrafluroethylene tube, a cellular polytetrafluoroethylene tube, a porous polytetrafluoroethylene tube, and an expanded polytetrafluoroethylene tube. 4. The method of claim 1, which includes rotating the body of the shrinkable tube and applying the designated amount of the coating to the section of the outer surface of the body of the rotating shrinkable tube. 5. The method of claim 1, wherein the curing of said coating includes curing the coating to a designated temperature of 650° F. for a designated period of time. 6. The method of claim 1, wherein the curing of said coating includes curing the coating to a designated temperature of greater than 500° F. for a designated period of time. 7. The method of claim 1, which includes curing said coating in a controlled environment with at least one effluent filtration system. 8. The method of claim 1, which includes further curing said coating using an energy source selected from the group consisting of: a radiant heat, induction energy, hot air, open flame, at least one electric filament, at least one magnet, and at least one laser. 9. The method of claim 1, wherein the first pigment is selected from the group consisting of: an organic pigment, an inorganic pigment, an extender pigment, a magnetic receptive pigment and a laser excitable pigment. 10. The method of claim 1, wherein the first pigment is selected from a group consisting of: a phthalocyanine blue, a phthalocyanine green, a diarylide yellow, a diarylide orange, a quanacridone, a naphthol, a toluidine red, a carbizole violet, a carbon black, an iron oxide red, an iron oxide yellow, a chrome oxide green, a titanium oxide white, a cadmium red, a ultramarine blue, a moly orange, a lead chromate yellow, a mixed metal oxide, a talc, a calcium carbonate, a silicate and sulfate, a silica, a mica, an aluminum hydrate and silicate, a barium sulfate, a pearl pigment, a kaolin, an aluminum silicate derivative, an antomony trioxide, a metallic pigment, an aluminum flake pigment, and an iron oxide. 11. The method of claim 1, wherein the coating includes a plurality of interspersed anti-microbial particles. 12. The method of claim 11, wherein the anti-microbial particles are selected from the group consisting of: silver particles, glass-silver particles, silver-ceramic particles, and ceramic particles. 13. The method of claim 1, wherein the at least one marking is selected from the group consisting of: at least one line parallel to a longitudinal direction of the shrinkable tube, at least one line perpendicular to the longitudinal direction of the shrinkable tube, at least one line transverse to the longitudinal direction of the shrinkable tube, at least one line substantially transverse to the longitudinal direction of the shrinkable tube, at least one spiral patterned line along the length of the shrinkable tube, at least one spiral patterned line along the width of the shrinkable tube, a plurality of parallel lines, a distance, a number, a letter, a bar code, a directional arrow, a size of the shrinkable tube, a type of the shrinkable tube, a material of the shrinkable tube, a part number of the shrinkable tube, a serial number of the shrinkable tube, a lot number of the shrinkable tube, a manufacturing date of the shrinkable tube, a plurality of instructions for use of the shrinkable tube, at least one warning associated with the use of the shrinkable tube, and a manufacturer of the shrinkable tube. 14. The method of claim 1, wherein the third outer diameter is equal to the first outer diameter. 15. The method of claim 1, which includes blocking at least another section of the body of the shrinkable tube to apply the coating to the section of the body of the shrinkable tube. 16. The method of claim 1, which includes not applying the coating to any outer surface of another section of the body of the shrinkable tube. 17. The method of claim 16, wherein the outer surface of the other section of the body of the shrinkable tube has a fourth outer diameter approximately equal to the third outer diameter. 18. A method of manufacturing a coated shrinkable tube, said method comprising: (a) applying a designated amount of a coating to an outer surface of a section of a body of the shrinkable tube, said section of the body of the shrinkable tube having a first outer diameter and a first outer radius, said applied coating including: (i) a first pigment of a first color, and (ii) a binder, said applied coating defining a first coating radial thickness; and(b) curing the applied coating to cause the applied coating to bond to the outer surface of the section of the body of the shrinkable tube to indicate at least one marking formed along the body of the shrinkable tube;wherein the curing causes (i) the section of the body of the shrinkable tube to shrink such that after curing, the section of the body of the shrinkable tube has a second outer diameter and a second outer radius respectively less than the first outer diameter and the first outer radius, (ii) the first coating radial thickness to shrink to a second coating radial thickness;the first coating radial thickness being sized such that after the curing: (x) the section of the body of the shrinkable tube with the cured coating has a third outer diameter approximately equal to the first outer diameter, and (y) a sum of the second outer radius and the second coating radial thickness is approximately equal to the first outer radius.
