Windings
Precision reinforcement and torque coils are engineered for strength, flexibility, and consistency in catheter systems, drive cables, and other minimally invasive devices.
EXCEPTIONAL CONTROL, FLEXIBILITY, AND TORQUE TRANSMISSION
Motion Dynamics manufactures precision reinforcement and torque coils designed to deliver exceptional control, flexibility, and torque transmission in the smallest-scale devices. Our coiling capabilities include variable-pitch windings and custom geometries optimized for specific mechanical or performance requirements. These coils are used in catheter shafts, delivery systems, and drive cables where smooth torque response, kink resistance, and dimensional stability are critical.
We control every process variable—from wire tension and pitch to coil diameter—to ensure repeatable geometry and mechanical uniformity across production lots. With expertise spanning stainless steel, Nitinol, tungsten, and platinum-based alloys, we provide reliable solutions for both prototyping and high-volume manufacturing. Our advanced forming and inspection systems ensure each coil meets the highest standards of precision and cleanliness required for critical applications.
Applications
- Reinforcement coils for catheter shafts and delivery systems requiring flexibility and kink resistance
- Torque coils for drive cables, steerable catheters, and powered device assemblies
- Variable-pitch coils engineered for controlled flexibility and mechanical response
- Micro-coiled wire structures for implantable or diagnostic applications
- Precision-wound coils for sensor, aerospace, and defense systems requiring repeatable mechanical and electrical properties
- Prototype-to-production coil programs with validated dimensional control and process traceability
Frequently Asked Questions
We produce precision reinforcement and torque coils used in catheter shafts, drive cables, and delivery systems that require flexibility, torque response, and dimensional stability at micro scales.
We manufacture coils using wire as fine as 0.001” (25 microns) in stainless steel, Nitinol, tungsten, and platinum-based alloys. Both round and flat or rectangular wire profiles are available to achieve specific mechanical, flexibility, or torque performance requirements.
Our coiling processes are tightly controlled for wire tension, pitch, and diameter using automated monitoring and in-process inspection. This ensures consistent mechanical properties and smooth torque transmission across all production lots.
Absolutely. We collaborate with OEM engineers to optimize coil geometry, mechanical performance, and manufacturability, supporting rapid prototyping and validated production with full traceability.
