Minimally invasive brain-computer interface (BCI) systems require highly reliable interventional catheters. The dual-lumen Pebax catheter is a key component for electrode delivery and auxiliary access in emerging neural interface platforms.
PT&C offers contract manufacturing services for BCI-specific dual-lumen Pebax catheters. We support the entire development cycle – from rapid prototyping to ISO 13485-certified volume production – using medical-grade, high-purity Pebax resin.
A dual-lumen Pebax catheter consists of a single tube with two independent, non-communicating lumens. These can be configured with equal or different diameters to suit your intended use.
Engineered Flexibility – Excellent kink resistance and torque transmission to navigate tortuous neurovascular routes.
Biocompatibility – Complies with ISO 10993 for short- or long-term interventional use.
Variable Durometer – Adjustable Shore D hardness options, allowing for a stiff proximal shaft for pushability and an ultra-soft distal tip to minimize tissue trauma.
We provide full-service customization across dimensions, material grades, and integrated features.
Outer diameter – Customized to your specific neurovascular access route.
Lumen sizes and ratios – Independently sized for main electrode delivery and auxiliary channels.
Length – Adapted to your specific BCI interventional procedure.
Cross-sectional profiles – Round, D-shaped, oval, or custom multi-lumen configurations.
Medical-grade Pebax available in a wide range of durometers (from soft 25D to rigid 72D).
Hydrophilic or smooth inner liners (such as PTFE or HDPE) to drastically reduce friction during electrode deployment.
Multi-segment durometer bonding along the shaft for optimal trackability and pushability.
· Radiopaque markers – Platinum-iridium or tantalum rings, or barium sulfate ($BaSO_4$) compounding for clear fluoroscopic visualization.
· Reinforcement layers – Braided or coil-reinforced shafts for superior kink resistance and torque response.
· Multi-lumen versions – Three-lumen or custom channels available on request.
Manufactured under ISO 13485:2016.
Each batch undergoes strict dimensional, visual, and flow-rate testing.
Pilot batches for R&D and regulatory testing; high-volume production for clinical trials and commercial supply.
Flexible lead times with rapid response.
Deep Pebax Extrusion Expertise – Years of precision co-extrusion, multi-durometer bonding, and tip forming experience.
End-to-end service – From tooling design to final catheter assembly, all in-house.
Regulatory support – We can supply Design History Files (DHF) and Device Master Records (DMR) for NMPA/FDA submissions.
IP protection – Strict NDAs and confidentiality agreements safeguard your proprietary designs.
Whether you are developing a novel endovascular BCI or upgrading an existing system, our engineering team is ready to translate your specifications into a manufacturable Pebax catheter.
