Smooth, Low Friction Mandrels and Stylets

Merit mandrels provide the consistent diameters, tight tolerances, and smooth, low friction surfaces you need to design and deliver catheter tube ID solutions with ideal characteristics and superior release properties. Merit mandrels are available in a variety of diameters and base materials, including stainless steel, Nitinol, and copper. Our unique continuous spool-to-spool precoating process makes it possible to apply PTFE coatings to Nitinol and other materials without compromising their elastic properties. We can deliver your coated mandrel wires in a variety of ways including on-spool, straightened, or cut to specific lengths. And we can apply a variety of final manufacturing and finishing processes, including laser ablation and laser-cut rounded and tapered ends.
