Explore our foundational range of hospital-validated single-use instruments, manufactured in class 100,000 cleanrooms and supplied to top distributors across 40+ countries.
Endoscopic Retrograde Cholangiopancreatography demands high kink resistance, distinct radiopaque visibility, and rapid balloon deflation. Discover how custom tooling resolves cross-talk between inflation, wire, and contrast channels.
Unlike compromised bi-lumen catheters, our tri-lumen profile maintains a distinct 0.035" guidewire channel, a low-viscosity contrast injection lumen, and an independent micro-balloon inflation conduit. This eliminates fluid back-pressure while reducing biliary procedural duration by 28%.
Balloon sleeves are blow-molded utilizing non-compliant medical grade elastomers that resist sudden bursting across lithiasis calcifications. The balloon holds three definite clinical outer diameters (8.5mm, 12mm, 15mm) across controlled incremental atmospheres without radial distortion.
Engineered with precisely centered platinum-iridium radiopaque marker bands stationed at the distal and proximal margins of the balloon shoulders. Guarantees real-time fluoroscopic placement inside the common bile duct (CBD) and the Ampulla of Vater.
Direct supply contracts with hospital systems demand precise catheter pushability, lumen tolerances, and trace certifications. Below is our OEM multi-lumen technical baseline engineered for global tenders.
| Evaluation Parameter | ZhuoRuiHua Multi-Lumen Standard | Conventional Bi-Lumen OEM | Clinical Advantage for GPO / Importers |
|---|---|---|---|
| Catheter Shaft Configuration | Tri-lumen co-extruded Pebax® / Polyurethane composite | Dual-lumen PVC or basic HDPE extrusion | 100% torque response, eliminating loop twisting inside duodenoscope elevators. |
| Guidewire Compatibility | 0.035" and 0.025" with PTFE internal low-friction lining | Unlined wire channel prone to galling | Effortless wire exchange even under tortuous cystic duct angles. |
| Biliary Contrast Delivery | Independent dedicated lumen; injection above or below balloon | Shared guidewire-contrast lumen | Allows contrast cholangiography without removing guidewire access. |
| Outer Diameter / Working Length | 7.0 Fr / 7.5 Fr, 2000 mm standard (Customizable) | 8.0 Fr+ rigid profiles | Fits smoothly inside 3.2 mm or larger therapeutic duodenoscope channels. |
| Regulatory Dossier Ready | ISO 13485:2016, CE MDR Class IIa, FDA 510(k) pathway data | Regional domestic clearances only | Accelerates importer registration in the EU, Middle East, and Latin America. |
How our vertically integrated Jiangxi manufacturing facility solves global distributor bottlenecks: from mold fabrication to destination customs documentation and private labeling.
Over 10,000 m² of automated injection molding, precision laser-welding, and ISO 11135 Ethylene Oxide (EO) sterilization chambers ensuring zero bacterial endotoxin loads.
Rapid tooling turnaround for private label branding, customized balloon printing bands, localized color codes on Luer ports, and bilingual blister packaging.
We provide full technical documentation—including ISO 10993 biocompatibility testing, accelerated aging reports, and stability data—to fast-track local ministry approvals.
Consolidated multi-SKU export shipments directly out of Shanghai/Shenzhen maritime hubs, maintaining sterile Tyvek barrier integrity across transcontinental shipping.
Engineered to adapt across high-difficulty therapeutic biliary procedures, offering physicians smooth tactility and minimal duodenoscope channel resistance.
Post-sphincterotomy removal of solitary or multiple stones from the common bile duct. The balloon's tapered distended geometry sweeps cleanly along the biliary wall without mucosal scraping or traumatic laceration.
Low-pressure balloon adjustments allow complete ductal clearance of fine biliary sludge, preventing recurrent post-procedure pancreatitis or bile duct bacterial colonization.
Used to seal the papilla during injection of radiopaque media, providing intense contrast visualization of hilar strictures, Klatskin tumors, and anomalous pancreaticobiliary duct junctions.
