Coils have a number of applications in medical devices, and Duke Empirical has the technology to provide the right coil for your application.  Coiled wires are commonly used to reinforce tubing, providing excellent kink resistance without lhoss of flexibility.  Spring loaded devices, vascular implants, and radiopaque catheters also commonly employ coil technology.   Duke Empirical has built custom computer controlled coiling equipment machine allowing us to build to  vary and control the pitch, diameter, and tension of  each custom coil. Our capabilities range from small coils (down to 0.002" I.D. with 0.001" diameter wire micro coils), to larger coils up to 0.50" I.D. and more. Examples of materials which we commonly coil include:

• Stainless Steel
• Nitinol
• Platinum/Iridium

Duke has the capability to build multiple braid configurations, using round or flat wire in a wide range of sizes. We operate 48-carrier, 24-carrier and 16-carrier braiding machines, on which we can run up to 4 ends each. Interwoven axial fibers can be added to the braid to increase tensile strength or provide additional lumens.

• Stainless Steel
• Nitinol
• Polymer
• PLA/PGA bioresorcbable threads
