Braided Catheter Shaft

OEM braided catheter shaft manufacturing for torque response, kink resistance, and controlled pushability in interventional catheter programs.

Target Buyer:Best for catheter R&D, process engineering, and sourcing teams that need a custom reinforced shaft instead of commodity tubing.

Capability Highlights

Stainless steel, nitinol, and flat wire braid reinforcement options
Pitch, pick count, braid angle, and transition-zone tuning
Multi-layer shaft stackups with PTFE liner, braid layer, and Pebax or nylon jacket
Prototype-to-production support for catheter OEM and CDMO teams

Typical Applications

Neurovascular microcatheters
Peripheral vascular access catheters
Structural heart delivery shafts
Steerable and deflectable catheter assemblies

Engineering Focus

Braid wire material, diameter, flatness, and tensile behavior
Braid density versus flexibility, torque transmission, and collapse resistance
Transition from hypotube proximal support to distal braided polymer shaft
Reflow window control to prevent liner damage, ovality, and jacket voids

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Typical shaft OD	0.6 mm to 5.0 mm project-dependent	OD drives braid equipment setup, liner choice, reflow tooling, and downstream device compatibility.
Braid reinforcement	Round wire, flat wire, stainless steel, nitinol	Material and geometry define torque transfer, kink resistance, radiopacity strategy, and fatigue risk.
Zone architecture	Single-zone, multi-zone, distal soft tip transition	Most high-value catheter shafts fail or win at the transition between pushability and atraumatic flexibility.

RFQ Checklist

Target catheter OD/ID, usable length, and shaft-zone drawing
Braid material, wire size, braid angle, and desired pitch if known
PTFE liner specification and outer jacket polymer preference
Required flexibility zones, torque response target, and kink test method
Prototype quantity, annual forecast, validation documents, and destination

Risk Controls

Braid wire imprint or jacket voids: Tune heat-shrink, reflow profile, jacket wall, and pull speed before pilot release.
Torque lag or distal whip: Review braid angle, pick count, polymer durometer sequence, and shaft-zone stiffness map together.
Prototype cannot scale: Lock equipment recipe, tooling ID, inspection method, and material lot traceability during sample build.

Buyer FAQ

Can you support custom braid patterns?

Yes. RFQs can specify wire count, braid angle, pitch, wire material, and shaft zones. If those are not frozen, we can start from application and OD/ID targets.

Is braided catheter shaft different from hypotube?

Yes. Hypotube is commonly used for proximal push sections, while braided polymer shaft is often used where flexibility, torque, and kink resistance must be balanced.
