Abstract
Coiled medical plastic tubing is set in the coil shape by exposing it to a radio-frequency field while it is subjected to slight radially inward pressure. The amount of pressure and the power of the RF field are so adjusted as to cause the rungs of the coil to lightly stick together without deforming or weakening the coil itself.
