Medical-Grade Balloon Tubing: Precision Multi-Layer & Single-Lumen Extrusions
At Carewe Medical, we understand that the performance of an interventional catheter depends heavily on the quality of its foundation. Our premium medical balloon tubing is engineered to meet the strictest dimensional tolerances and burst pressure requirements in the industry.
Whether you are developing high-pressure PTCA dilation catheters, compliant PTA balloons, or complex delivery systems, our state-of-the-art co-extrusion technology ensures exceptional concentricity, optimal trackability, and reliable thermal bonding.

Key Features & Production Advantages
- Superior Concentricity: Utilizing continuous in-line laser measurement systems, we achieve a concentricity rating of over 95%, ensuring uniform wall expansion and eliminating weak points during balloon blowing.
- Optimized Co-Extrusion (Multi-Layer Technology): We can extrude specialized tri-layer tubing (e.g., HDPE inner layer for low-friction wire tracking, a tie-layer, and a Pebax outer layer for effortless thermal bonding to the catheter shaft).
- Enhanced Parison Performance: Our extrusion process minimizes molecular stress anisotropy, providing your R&D team with optimal parisons that translate to high burst pressures and low compliance profiles.
- Biocompatibility & Compliance: Manufactured in ISO Class 7 (Class 10,000) cleanrooms, fully compliant with ISO 13485 standards.
Applications
- Coronary (PTCA) and Peripheral (PTA) Intervention Balloons
- Transcatheter Aortic Valve Replacement (TAVR) / Structural Heart Delivery Systems
- Stent Delivery Systems (SDS Shafts)
- Endoscopic and Urological Dilation Catheters
Frequently Asked Questions (FAQ Section)
Q1: Can you provide custom blended or compounded Pebax materials for specific stiffness?
A1: Yes. We specialize in custom compounding. We can blend different durometers of Pebax (e.g., mixing 72D and 63D) or introduce additives to enhance trackability, kink resistance, or radiopacity, tailored to your precise balloon mold requirements.
Q2: What is your standard lead time for custom balloon tubing samples?
A2: For standard configurations and stocked resins (like Pebax 72D or PA12), we can dispatch prototyping samples within 1–2 weeks. Custom multi-layer co-extrusions typically take 3–4 weeks depending on tool customization.
