Application Evaluation Matrix
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Wall thickness | Ultra-thin | Maximizes inner lumen for device passage. |
| Flexibility control | Nitinol tube, spiral cut, slot pattern, or thin-wall SS | Determines whether the component can navigate tortuous neurovascular anatomy. |
| Surface and burr control | Microscopy, electropolish, passivation, cleaning | Small defects can dominate risk in microcatheter and coil delivery components. |
Buyer Decision Points Before RFQ
| Decision Factor | Confirm Before Quote | Buyer Impact |
|---|---|---|
| Anatomy-driven flexibility | Target vessel path, bend radius, distal softness, and kink-resistance expectation. | Connects material and laser pattern choices to the access path instead of using generic tube sizes. |
| Lumen preservation | OD/ID/wall stack, concentricity, ovality, and guidewire or device passage requirement. | Protects usable lumen in microcatheters where every micron affects flow or device passage. |
| Defect sensitivity | Burr limit, edge radius, HAZ/recast tolerance, inspection magnification, and cleaning route. | Reduces the chance that a small feature defect becomes a validation failure. |
Risk and Mitigation
- Wall collapse: Rigorous concentricity and thickness inspection.
- Traumatic edge condition: Treat cut-edge inspection, burr limits, and surface finishing as release criteria.
Application Build and Release Flow
- Clinical path translation: Translate neurovascular access needs into bend, flexibility, OD, ID, and surface requirements.
- Material and feature review: Evaluate nitinol, stainless, laser cuts, thin-wall tubing, and marker interfaces against the drawing.
- Micro finishing: Control burrs, surface condition, and cleanliness using electropolishing, passivation, or targeted cleaning.
- Inspection package: Release samples with CTQ dimensional data and visual evidence for high-risk micro features.
Quality Evidence Buyers Can Request
- Concentricity, wall, OD/ID, and ovality checks for ultra-thin features
- Microscopic edge and slot inspection for burr, recast, and bridge integrity
- Surface finish and cleaning confirmation when specified
- Material traceability for stainless, nitinol, or radiopaque components

Buyer FAQ
What is the minimum wall thickness?
Depends on material, often down to 0.001".
Is nitinol or stainless better for neurovascular components?
Nitinol is preferred when superelastic recovery and extreme flexibility are central; stainless steel can fit support sections where pushability and predictable tube dimensions matter more.
