Nexans introduces 15 micron thickness micro cable to open up new medical fields

Modern medicine constantly pursues the development of minimally invasive surgical and diagnostic procedures
.
This presents a major and ongoing challenge for medical device manufacturers to increase the miniaturization
of their components.
Providing these tiny devices with significant power and data connections is driving the development of a new generation of miniature cables with diameters of
only 0.
1 mm or less.

Nexans introduces 15 micron thickness micro cable to open up new medical fields

RECENTLY, THE MARKET IS CHANGING WITH THE INTRODUCTION OF NEXANS' NEWSENSE® SERIES OF MINIATURE CABLES, WHICH HAVE AN INSULATION SHEATH THICKNESS OF ONLY 15 MICRONS
.

Although medical miniature cables must ensure the performance, reliability and safety necessary for any medical application, their size also plays a decisive role
in reducing the effects of invasive operation.
One of the main limiting factors in cable miniaturization is the thickness
of the insulation sheath.
Until now, with the "standard" extrusion process, it was not possible to reach a thickness
of 30 microns.
Although at this size, the insulation is slightly thinner than the finest human hair (75-125 microns), it still occupies 84%
of the entire cross-section of a 0.
1 mm diameter cable.

With its new extrusion process, Nexans was able to reduce the insulation thickness of its NEWSENSE® cables to 15 microns
.
This allows for the manufacture of smaller diameter cables, providing various advantages
for invasive procedures.
They are easier to insert into catheters, for example in transcatheter applications
in cardiovascular electrophysiology and neurology.
When used for direct insertion into the body, such as pacemakers, they are also less
traumatic to the patient.

Another benefit of the new design is that it can integrate more cables within the same cross-section, improving performance
.
The extruded layer is also smoother, regular and aesthetically pleasing, as well as easier to terminate peeling
.

One of the first NEWSENSE® designs was a new space-saving cable
for transcatheter applications.
This design uses two AWG52 (20 micron diameter copper diameter) insulated wires stranded together
as twisted pairs.
Shielding against external electromagnetic interference is provided
by 15 micron diameter wires in a silver-plated copper alloy.
Externally, the cable has a biocompatible, low-friction fluoropolymer sheath with a final outer diameter of 0.
14 mm
.

"The medical cable market is growing by about 5-10% year-on-year and the development of new microcables will allow Nexans to strengthen its already strong position and open up some exciting possibilities
for new applications.
" Product Manager T?? Hierry Malvache said, "This project really promotes the development of extrusion technology, and its success is an affirmation
of the high level of cooperation between our medical cable factory and the Nexans Research Center in Lyon.
”

NEWSENSE® miniature cables and other medical cables will be manufactured
at Nexans' specialized facility in Texas, France.
