Abstract
A metal article has a coating of a noncuring polar lubricant. Preferred articles are of stainless steel and may be cutting devices such as needles, lancets and cannulas or sliding devices such as stylets and guidewires. Preferred noncuring polar lubricants are polysiloxanes terminated with a polar group. Particularly preferred lubricants are aminoalkyl or carboxyalkyl polysiloxanes. The lubricated metal article may be in a sliding relationship with a plastic article such as a catheter-guidewire or a catheter-cannula assembly. The plastic portion of the assembly may also include a lubricant.
