HOTLINEPlated Radiopaque Wires Increase Functionality
Compared with welded units, the components offer greater flexibility and decreased profiles

Replacing welded units, plated radiopaque wires from Scilogy Corp. (Miami) can increase functionality in a variety
of medical applications. "Traditionally, radiopaque wire devices have been constructed by soldering a radiopaque and a nonradiopaque wire segment together end to end, but this results in a stiff joint that lacks flexibility and that can bend during use," explains president Frank Vellined. "Our LCX wires eliminate these problems because they consist of a nitinol or stainless-steel coil that is plated with, rather than welded to, gold or platinum for radiopacity," he says.
According to Vellined, this plated design also translates into cost savings for device manufacturers, as it requires less of the expensive radiopaque materials than welded models. "The LCX wires offer the same level of radiopacity as precious-metal wires, but at half the cost," he says. Other product benefits are said to include higher conductivity, greater flex life, and decreased device profiles.
LCX wires are supplied in diameters ranging from 0.001 to 0.062 in. and in lengths up to 80 in. Shipped in coils, the wires can be customized to produce different levels of stiffness and radiopacity. Multifilar, tapered, close-wound, and variable-pitch configurations are available. Product applications span guidewires, high-conductivity leads, stents, aneurysm coils, springs, catheter wires, and flexible endoscope shafts.
