Abstract: Methods of manufacturing a length of a flexible polymeric medical tubing of the kind comprising a tubing member defining a lumen, which tubing member is surrounded by spiral convolutions along at least a part of the length of the proximal section and/or the distal section, and which medical tubing has a proximal convoluted section and a distal convoluted section, is disclosed, as well as medical tubings obtained by the methods and their uses. One method comprises the steps of providing a medical tubing wherein the proximal section and the distal section have substantially uniform initial pitch (Pinitial) between adjacent convolutions, and modifying the initial pitch (Pinitial) of at least a part of the proximal section by stretching at least a part of the proximal section to achieve a modified proximal section with a proximal pitch (Pproximal) between adjacent convolutions that is larger than the initial pitch (Pinitial) between adjacent convolutions. In another method the medical tubing is manufactured in a molding process. The so obtained medical tubing is particularly suited for use in open surgical procedures that requires suction and/or irrigation during use of an electrosurgical instrument.

Abstract: The present invention relates to a device for shaping and cooling a smooth thin wall pipe, obtained from extrusion of a thermoplastic material, into a corrugated pipe shape.The most common technology to produce plastic corrugated pipe uses a series of split molds carried by two continuous chains, the split molds locking around an extruded smooth pipe which by means of a slight positive pressure is forced against the inside walls of the molds (which travel at extrusion speed) therefore shaping the hot plastic pipe into a corrugated shape. At the same time excessive heat is dissipated by a forced flow of air passing over the outside surface of the molds. This system requires a great number of molds and therefore machines of great encumberance.
