Abstract
Disclosed herein are sterilized medical coiled tubing and process for producing the same. One process comprises: helically winding a length of the medical tubing along a mandrel such that adjacent turns of the medical tubing are in contact with each other; applying solvent where the turns of the medical tubing contact each other to produce coiled medical tubing; allowing the solvent to dry; removing the medical tubing from the mandrel after the solvent has dried; and subjecting the medical tubing to a sterilization process using ethylene oxide with in-chamber aeration.

A process for producing a sterilized medical tubing coil, comprising:
- helically winding a length of the medical tubing along a mandrel such that adjacent turns of the medical tubing are in contact with each other;
- applying solvent where the turns of the medical tubing contact each other to produce coiled medical tubing;
- allowing the solvent to dry;
- removing the medical tubing from the mandrel after the solvent has dried;
- and
- subjecting the medical tubing to a sterilization process using ethylene oxide with in-chamber aeration.
An apparatus for producing a medical tubing coil, comprising:
- a mandrel configured to helically wind a length of the medical tubing along the mandrel such that adjacent turns of the medical tubing are in contact with each other;
- and
- a pin configured to apply solvent where the turns of the medical tubing contact each other to produce coiled medical tubing.
- wherein the solvent is allowed to dry before removing the medical tubing from the mandrel;
- and
- wherein the coiled medical tubing is subjected to a sterilization process using ethylene oxide with in-chamber aeration.
A product made by a process comprising:
- helically winding a length of medical tubing along a mandrel such that adjacent turns of the medical tubing are in contact with each other;
- applying solvent where the turns of the medical tubing contact each other to produce coiled medical tubing;
- allowing the solvent to dry;
- removing the medical tubing from the mandrel after the solvent has dried;
