PTFE lined catheter shaft builds with braid or coil reinforcement, jacket reflow, and lumen-focused process control for low-friction delivery systems.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Liner ID control | Defined by guidewire/device clearance | Small ID drift can cause friction, delivery failure, or unacceptable clinical device feel. |
| Jacket bonding | Validated by peel, bend, and visual criteria | Weak bonding causes delamination, ballooning, and unpredictable shaft behavior. |
| Surface quality | No exposed reinforcement or reflow defects | Outer surface defects can compromise device trackability and regulatory acceptance. |
Yes. We can quote a preliminary process path from ID/OD, device clearance, and reinforcement requirements, then finalize after liner selection.
Yes. Lumen pass-through, visual surface inspection, concentricity, and bend testing should be agreed before sample release.
