Component Supply offers a wide selection of in-stock medical device wires and mandrels, engineered for catheter design, minimally invasive devices, and medical device R&D. Our products support prototyping, benchtop testing, and production-scale projects, delivering tight tolerances, consistent materials, and reliable performance. Available materials include 304 and 316 stainless steel wire for mandrels, stylets, and catheter components, superelastic Nitinol wire for shape-memory applications, PTFE and GlideMed® coated mandrels for inner lumen protection, Music Wire for precision mechanical assemblies, and PTFE or stainless steel guidewire assemblies for ready-to-use prototyping and validation. We also offer 304 SS Medical Wire Lab Kits to test multiple mandrel diameters during R&D and catheter development.
All wires and mandrels ship in straight lengths without end forms, with standard lengths of 36″ or 72″, and custom lengths or fabrication available via our Quote Form. Click part numbers for technical drawings, specifications, and related products. This flexible ordering approach ensures engineers and designers have the materials they need for both R&D and production-scale catheter projects.
Component Supply wires and mandrels are widely used in medical device R&D, prototyping, and production, with a strong emphasis on catheter design, guidewire assemblies, and precision mandrels. Our products provide tight tolerances, consistent materials, and reliable performance for demanding medical applications.
Stainless Steel Mandrels & Straight Wires – Ideal for catheter mandrels, stylets, introducers, push-pull rods, and guidewire assemblies.
Guidewire Assemblies – Used across coronary, gastroenterology, renal, urology, obstetrics/gynecology, radiology, and peripheral vascular applications.
Actuators & Push-Rod Assemblies – Stainless steel and Nitinol wires are used in mechanical assemblies requiring precise movement and strength.
Superelastic Nitinol – Supports catheter mandrels, guidewires, mechanical switching devices, prosthetics, robotic actuators, stents, and superelastic needles.
Coated Mandrels – PTFE and GlideMed™ coated mandrels preserve catheter inner diameter (ID) integrity during reflow, bending, and assembly.
While Component Supply focuses on medical device development, our wires are also used in industrial applications:
304 Stainless Steel Wire – Spring-tempered for manufacturing springs and structural components
Music Wire – High-stress compression, extension, and torsion applications requiring repeatable performance
Component Supply provides comprehensive wire and mandrel fabrication capabilities for medical device R&D, catheter development, and production-scale applications. Our services support precision tolerances, complex geometries, and high-performance components across all commonly used medical wire materials, including 304 and 316 stainless steel, Nitinol, PTFE-coated wire, and GlideMed™ coated wire.
