Nexans: Micro-process technologies dedicated to medical applications

Nexans, France, Hall 8b, Stand G29

The development of minimally invasive surgery and the general miniaturization trend in healthcare equipment require even smaller medical devices and components. To answer market needs with its NEWSENSE™ medical range, Nexans has introduced new technologies to produce and control miniature cables down to AWG52 conductors (20 microns diameter). As a comparison, human hair diameter ranges from 50 to 100 microns!

Fine tension regulation system have been installed at each step of the cable production process (wire insulation, assembling, shielding, jacketing) to avoid any thin wires elongation or deformation and to provide consistent geometry.

"We can control the pull force over wires in line down to several grams, which makes possible the stranding of AWG52 conductors or the shielding by 15 microns wires diameter" explains Thierry MALVACHE, Nexans medical product manager.

Also, new jacketing technology using micro-extruder with material output less than 1g/min has been developed. "This process enables us to reduce our cable outer jacket thickness down to 15 microns which is prominent for space saving design" said Thierry MALVACHE.

Non destructive and contact-free measurement systems have been installed in production lines in order to detect micro defects (down to 5 microns size) and to control with perfect reliability, along 100% cable length, the dimensions, the geometry and the dielectric strength of insulation.
