Coil Winding and Reinforcement
Precision coil winding process support for medical catheter shafts requiring continuous support and high distal flexibility.
Best Fit For:For R&D and process engineers needing precise, repeatable coil pitch control without investing in internal winding equipment.
Capability Highlights
- Round and flat wire coil winding on mandrel
- Variable pitch control for flexibility gradients
- Integration with PTFE liners and polymer jackets
Typical Engagement Scope
- Flexible microcatheters
- Endovascular delivery shafts
- Introducer sheath sections
Execution Focus
- Wire tension and springback control
- Pitch consistency across long shaft sections
- Transitioning from proximal braid to distal coil
Program Evaluation Matrix
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Pitch consistency | Application specific | Inconsistent pitch causes variable stiffness and unpredictable kink behavior during clinical use. |
Risk and Mitigation
- Coil unwinding during reflow: Control wire tension, anchoring methods, and jacket shrink pressure during thermal processing.

Buyer FAQ
Can you wind over a custom PTFE liner?
Yes, provided the liner and mandrel combination can withstand the winding tension without deformation.
