Wire Improves Cardiovascular Catheter Manufacturing

This Teflon coated extrusion wire is fabricated using a proprietary etching process that eliminates flaking and permits over 25% elongation to keep the catheter's inside diameter clean. Supplied spooled or cut to length, this fine extrusion wire features a 0.05 coefficient of friction that prevents sticking and simplifies its removal from the catheter. Providing a slippery, anti-stick surface, the wire can be produced using stainless steel, nitinol, platinum, and silver-plated copper core wire. Sizes can range from 0.001? to 0.07? dia. with a 0.0001? per side Teflon coating. Applications include cardiovascular and epidural catheters, formed balloons, and other biocompatible devices.
