Guidewire Finish Types

Modern Grinding offers the following types of guidewire finishes:

  • Electropolish - Electropolish will provide your wire with a nice professional shine. It can also be referred to as electrochemical polishing or electrolytic polishing. The process of electro polishing is used to polish, deburr and passivate metal parts. Typical examples are electropolished stainless steel surgical devices.

  • Passivation - Passivation is a chemical process that is used to help restore contaminated stainless steel to original corrosion specifications.

  • PTFE Coating- PTFE is a thin, smooth coating which can be applied to medical wire devices. It is used to achieve optimum release or slip properties. Modern Grinding uses this technology to coat stainless steel or nitinol forming wires for use in catheters or stand alone wires.

  • Threaded - Modern Grinding uses subtractive grinding to achieve threading on ultra fine wires. We can create custom threads to spec on full length wires or across partial sections of wires.

  • Smooth - Smooth is the standard finish. Modern Grinding can manufacture medical part finishes within very small tolerances.

  • Herapin Coating - Heparin is a sulfated glycosaminoglycan used commonly in hydrophilic coatings because it is anti-thrombogenic. Heparin Coating is among the best in biocompatible coatings on the market. Heparin has been used as a hydrophilic coating in medical devices for nearly three decades.
