An apparatus for and method of manufacturing an improved wire-reinforced plastic tubing for medical and other applications is disclosed. A plurality of spaced-apart wire segments may be wound onto successive portions of a long segment of plastic tubing which portions are supported for rotation to wind coil wire thereon by rotating the plastic tubing while a supply of coil wire is wound onto the plastic tubing. When multiple winding segments have been wound on the long segment of plastic tubing, the segments may be separated into individual wire-reinforced tubing products each having one or more wire windings thereupon.

A method as defined in claim 6, wherein the securing step is performed by welding the first and second opposite ends of the at least one wire winding. 8. A method as defined in claim 6, wherein the securing step is performed by adhesively securing the first and second opposite ends of the at least one wire winding. 9. A method as defined in claim 1, wherein the rotating step is performed to helically wind at least two spaced-apart wire windings onto the portion of the plastic tubing located intermediate the air chucks. 10. A method as defined in claim 1, wherein the installing step comprises: spraying a plastic coating onto the extended length segment of plastic tubing with multiple sets of wire windings thereupon. 11. A method as defined in claim 1, wherein the installing step comprises: passing the extended length segment of plastic tubing with multiple sets of wire windings thereupon through a container having a coating material therein to apply an outer coating onto the extended length segment of plastic tubing with multiple sets of wire windings thereupon. 12. A method as defined in claim 1, wherein the installing step comprises: feeding the extended length segment of plastic tubing with multiple sets of wire windings thereupon through an extruder to extrude an outer coating onto the extended length segment of plastic tubing with multiple sets of wire windings thereupon. 13. A method of manufacturing wire-reinforced plastic tubing segments, comprising: supplying an extended length segment of plastic tubing having an extended length segment of plastic support tubing located inside the extended length segment of plastic tubing from a supply reel;supporting a portion of the plastic tubing/plastic support tubing supplied from the supply reel intermediate two spaced-apart air chucks, the portion of the plastic tubing/plastic support tubing located intermediate the air chucks defining an axis of rotation;taking up the plastic tubing/plastic support tubing onto a take-up reel;simultaneously rotating the supply reel, the air chucks, and the take-up reel about the axis of rotation while supplying a reinforcing wire to the portion of the plastic tubing/plastic support tubing located intermediate the air chucks to helically wind at least one wire winding onto the portion of the plastic tubing/plastic support tubing located intermediate the air chucks;welding first and second opposite ends of the at least one wire winding that is helically wound onto the portion of the plastic tubing/plastic support tubing located intermediate the air chucks;releasing the air chucks and advancing the plastic tubing/plastic support tubing from the supply reel to the take-up reel to advance a subsequent portion of the plastic tubing/plastic support tubing to the location between the air chucks and supporting the subsequent portion of the plastic tubing/plastic support tubing with the air chucks;repeating the rotating, welding, and releasing steps;installing an outer plastic layer over the exterior of the plastic tubing and the wire windings thereupon;cutting the plastic tubing into segments each having at least one wire winding; andremoving the plastic support tubing from the segments of plastic tubing. 14. A method of manufacturing wire-reinforced plastic tubing segments, comprising: providing an extended length segment of plastic tubing;supporting a portion of the plastic tubing intermediate two spaced-apart air chucks, the portion of the plastic tubing located intermediate the air chucks defining an axis of rotation;simultaneously rotating the air chucks about the axis of rotation while helically winding a wire winding onto the portion of the plastic tubing located intermediate the air chucks;releasing the air chucks and advancing the plastic tubing to provide a subsequent portion of the plastic tubing to the location between the air chucks and supporting the subsequent portion of the plastic tubing with the air chucks;repeating the rotating and releasing steps;installing an outer plastic layer over the exterior of the plastic tubing and the wire windings thereupon; andcutting the plastic tubing into segments each having at least one wire winding. 15.
