Shanghai Yike to Showcase Mass-Production-Ready Cholangioscopy Octa-Lumen Catheter with End-to-End Certainty at CCME 2026

On July 22–23, 2026, the CCME2026 10th Endoscopy Conference & Global Medical Device Innovation Conference will be grandly held at the Yangtze River International Conference Center in Nanjing. ECO Polymer, specializing in precision medical catheters and polymer solutions, will make a prominent appearance at Booth B101 (Custom-Built Booth), showcasing on-site a one-stop, guaranteed mass production solution for core products such as the biliary cholangioscope eight-lumen catheter.

For choledochoscope manufacturers, although the eight-lumen tube is classified as "tubing," it is by no means merely a "conduit" for connecting components. It serves as: an instrument channel, an imaging channel, a four-way steering wire channel, and an integrated platform for irrigation, suction, and light transmission. More critically, it directly determines whether physicians can achieve three types of "predictable procedural experiences"—Precise Rotation(Handle rotation, synchronized distal response)、No Discount(kink-resistant and non-collapsible in tortuous bile ducts),“Passable”(Sufficiently small bend radius to access complex anatomy.)

However, the reality is that professionals who have overseen the product introduction or mass production ramp-up of biliary daughter scopes have likely encountered this pitfall: while prototypes appear flawless, issues suddenly multiply upon entering pilot production—torque transmission degrades across batches, kink resistance fluctuates, and tactile feedback becomes inconsistent... ultimately delaying validation progress and driving up rework costs.

The fundamental risk of procuring an eight-lumen catheter is: what you are purchasing is not "a good catheter," but a reproducible process window.

Three "Hidden Costs" of the Biliary Subscope 8-Lumen Tube

Pain Point 1: Excellent Samples, but Inconsistent Mass Production Batches (Most Common and Critical)

Despite identical engineering drawings and nominal specifications, inter-batch variations may still occur, manifesting as degraded torque transmission, fluctuating flexural resistance, or even an irreproducible "handling feel" for the same model. The root cause lies in the fact that most suppliers rely on the "craftsman's empirical skill" during the prototyping phase to achieve impressive results, yet the manufacturing process window has not been truly locked in.

Pain Point 2: Geometric deviations in the eight-lumen structure are "amplified" during assembly and clinical application.

In an eight-lumen structure, the functional requirements for the pull-wire lumen, imaging lumen, and instrument lumen are distinct. Any occurrence of lumen eccentricity, diameter fluctuation, or non-uniform wall thickness will trigger a chain reaction: deviations in the pull-wire lumen result in asymmetric deflection and increased friction; fluctuations in the imaging lumen cause assembly interference and positional drift; while drift in the instrument lumen compromises tight-fit assembly or sealing stability.

Pain Point 3: Segmented Hardness and Transition Zone Process Are the "Ceiling" for Yield Rates

The true yield challenge often lies not in the straight section, but in the "transition zone". Steps, necking, interfacial slippage, delamination risks, thermal damage... these issues may not surface during the prototyping phase, yet they tend to converge and trigger critical failures during bending cycles, fatigue testing, and mass production.

`ECO Polymer`

The "Definitive Base" of the Eight-Lumen Cholangioscope Catheter

ECO Polymer，Leveraging 16 years of deep expertise in the medical device industry, the company has established strategic partnerships with dozens of leading international manufacturers across Europe, the United States, the Middle East, India, and South Korea, and has developed a multi-site production network in China（Shanghai, Zhejiang）and Central America（Costa Rica）. The company operates a 2,000-square-meter R&D center in Lingang, Shanghai, a 1,500-square-meter facility in Zhangjiang, and a 7,000-square-meter Class 10,000 cleanroom manufacturing plant in Taizhou, Zhejiang, with an additional 13,000-square-meter cleanroom facility currently under construction. It has obtained medical-grade certifications including “National High-Tech Enterprise” and “BSI ISO 13485”, holds a cumulative total of 54 invention and utility model patents, and has secured over RMB 100 million in funding from renowned investment firms such as Genesis Capital, Qiming Venture Partners, and SDIC Innovation Capital.

Addressing the aforementioned industry pain points, ECO Polymer has established a comprehensive delivery system centered on "mass production certainty," rather than providing a service that merely ensures "satisfaction with a single sample":

Solution 1: Mass Production Consistency Solution — “Process Window Locking + Closed-Loop Batch Release”

Corresponding Pain Point: Excellent samples, but poor batch-to-batch consistency in mass production.

Procedure：Key CTQs are decomposed into controllable process parameters, reverse-mapping clinical terminology such as torque transmission, kink resistance/ovalization, and handling feel into controllable process elements including braiding angle/coverage, filament diameter and tension, and batch viscosity windows for inner liner/outer layer materials, thereby establishing upper/lower parameter limits and parameter linkage rules; small-batch OPQ verification identifies primary factors affecting performance to establish a "reproducible process window"; a traceability chain is maintained for each batch of materials and finished products (covering raw material batches, equipment IDs, key parameter records, in-line dimensional/appearance checks, and off-line performance sampling results), enabling abnormal batches to be rapidly traced to specific process nodes.

Solution 2: Geometric Precision Solution——"Eight-Cavity Alignment Control + Assembly-Guided Tolerance System"

Corresponding Pain Point: Eight-Chamber Geometric Deviation Amplified During Assembly and Clinical Application

Procedure：First, define the relative angle and maximum eccentricity of the pull-wire lumens, the straightness/roundness requirements of the imaging lumens, and the tolerance and sealing fit configuration of the instrument lumen, using the "functional lumen" as the reference baseline for eight-lumen alignment control; implement a "dual verification" system combining OD/wall thickness trend monitoring with quantitative cross-sectional geometric evaluation to intercept geometric deviations prior to factory release; and directly map the key geometric metrics of the eight-lumen structure to customer assembly CTQs (e.g., pull-wire channel friction, imaging component interference, instrument deliverability, and sealing performance), thereby eliminating the gray area where "the tube passes inspection but fails during assembly."

Solution 3: Transition Section Yield Optimization Solution —— "Segmented Hardness Engineering + Transition Interface Reliability Process"

Corresponding Pain Point: Segmented Hardness and Transition Zone Processing are the Yield Ceiling

Procedure：To address the mechanical requirements of proximal pushability, transitional support, and distal flexibility, specific hardness/braid density/wall thickness combinations are defined for different segments, with reproducible gradient transitions achieved through a robust manufacturing process; by optimizing the transition zone length, step profile, and heat treatment window (temperature zones, duration, and cooling method), interfacial stress concentration is minimized to control delamination risk; bending cycles, torsional cycles, and rebound consistency serve as release criteria to prevent “passing initial inspection but failing during use”.
