Coil Reinforced Catheter

Coil reinforced catheter shaft OEM service for flexible, kink-resistant designs where continuous support and soft distal behavior are required.

Target Buyer:Best for device teams prioritizing smooth flexibility, lumen stability, and controlled distal support.

Capability Highlights

Metric	Typical Range	Why It Matters
Coil pitch	Application-specific tight or open pitch	Pitch determines support, flexibility, kink behavior, and jacket flow into the reinforcement layer.
Lumen retention	Defined by customer test fixture	Catheter performance depends on maintaining usable lumen under bending and compression.
Thermal process window	Validated per polymer stack	PTFE liner and jacket materials need controlled reflow to avoid delamination or deformation.

Coil pitch variation: Use controlled mandrel setup, tension control, and in-process visual measurement.
Liner wrinkling or ID loss: Validate mandrel surface, thermal profile, and post-process lumen inspection.

Coil reinforcement is often preferred when distal flexibility and continuous support matter more than maximum torque transfer.

Yes. Hybrid shafts can combine proximal braid with distal coil sections when the device needs both torque response and a soft distal path.
