What We Build for Medical OEMs
FROM PATIENT MONITOR
TO MRI ROOM.
XUDONG Cavite serves Class II and Class III medical device OEMs across the United States, Germany, Japan and Korea. Our medical cable portfolio includes patient-monitor cables (ECG, SpO2, NIBP, IBP, temperature), infusion pump harnesses, diagnostic-imaging signal cables (ultrasound transducer, endoscope camera), and equipment-side cables for surgical robots and dental imaging chairs.
All medical builds run inside a cleanroom carve-out with garment, glove and ESD-strap protocols. We maintain a Device Master Record (DMR) and Device History Record (DHR) per device family — engineering change orders flow through a documented design-control loop tied to ISO 13485 §7.3. Material library is biased toward USP Class VI TPU and PVC-free jackets, which we stock locally for sub-7-day repeat lead time.
Programs route through overmolded harness cells when patient-contacting strain reliefs are required, our custom wire harness workflow for diagnostic-imaging cables, and electromechanical assembly for cabinet-level diagnostic imaging modules.

Japan-Domiciled Client Support
For Japanese medical device OEMs, XUDONG operates a Tokyo-based subsidiary (Xudong Japan Co., Ltd., Fuchu-Shi) that supports Japanese-language pre-sales, drawing review, quality-document exchange, and on-site visit coordination. Wire harness production stays in Cavite, while program management can run end-to-end in Japanese — useful for ISO 13485 documentation, FDA submission support, PMDA stakeholder coordination, and IATF 16949 audits where Japanese-side communication needs to stay precise.

Buyer Pain Points
FOUR THINGS THAT
SLOW MEDICAL PROGRAMS.
Challenge #1
Biocompatibility evidence gaps after a material change
Your contract manufacturer swaps a PVC compound source mid-program; the existing ISO 10993-5 cytotoxicity report is now invalid against the new lot. Regulatory submission slips three months while you re-run animal testing.
How XUDONG addresses it
We lock biocompatible materials at PPAP-equivalent gate — every USP-VI TPU lot is sourced from the same compound supplier under a controlled material specification. ISO 10993-5/-10 / -11 reports stay valid because the formulation does not drift.
Challenge #2
DMR/DHR drift between supplier and device file
Your device master record references a 2021 cable revision; your supplier produces 2024 revision because they changed insulation supplier. FDA inspection finds the gap and your QMS opens a CAPA.
How XUDONG addresses it
Engineering change orders flow through a single ECO board. Cable revision is locked to BOM revision; revision label is printed on every harness. Supplier-side material changes trigger automatic DMR review before production.
Challenge #3
Cleanroom protocol violations from cross-trained operators
An operator who builds automotive harnesses on Tuesday and medical on Wednesday brings a contamination risk — fiber, oil, skin cells — into a Class 100K carve-out unless protocol is enforced.
How XUDONG addresses it
Medical operators are dedicated, not cross-trained from automotive lines. Garment, glove and ESD-strap protocol audited daily by quality cadre. Cleanroom carve-out has air-shower entry and dedicated tooling kit.
Challenge #4
Sterilization compatibility unknowns (EtO / gamma / autoclave)
Your device-level sterilization is gamma at 25 kGy. The cable jacket your supplier picked is rated to gamma but only at 15 kGy; resistance drift after sterilization fails functional test.
How XUDONG addresses it
Material library tagged by sterilization compatibility (EtO / gamma 25–50 kGy / steam autoclave). We pre-screen jacket and overmold compounds against your sterilization spec at DFM stage and flag any mismatches before quotation.

Anonymized Case Study
US TIER-1 PATIENT MONITOR OEM
(PUBLICLY HELD).
Customer: NYSE-listed US patient-monitoring OEM (Class II 510(k)-cleared device family). They needed to dual-source 8 SKUs of patient cable — ECG 3-lead, ECG 5-lead, SpO2 reusable, NIBP, IBP, temperature, defibrillator paddles, and pacing cable — out of an Asian site after their incumbent Mexican supplier missed two consecutive on-time targets.
We took over Q2 2023. Material library locked at USP-VI TPU. Cleanroom carve-out validated via on-site audit by customer quality. First production lot shipped week 9. Through 2024, we delivered 48,000 cables across the 8 SKUs with zero device-level field complaint and 99.6% on-time delivery to customer line.

Founder Note · Mr. Fei Bo Hu
“Medical cable work taught us that documentation is half the product. A patient-monitor cable is mechanically simpler than a 600 V EV harness, but the DMR + DHR + sterilization-compatibility paper trail takes more engineering hours than the assembly itself. We built our medical line around that reality — documentation engineers sit on the line, not in head office.”

A Build We Already Shipped In This Lane.
Scenario
A US electrical supply distributor required custom wire harnesses with specific Molex connectors, but a production batch had a dyeing/color deviation on the connector housings.
Challenge
Approximately 200 pieces of the wire harness assembly had connector coloring that did not match the strict aesthetic and technical requirements, risking rejection and project delay.
Outcome
Successfully reworked and delivered the batch without losing the client's trust; the client continued to place repeat orders in the following months without quality complaints.
