ZNG Medical
Engineered for precise anatomical navigation, torque responsiveness, and low-friction pushability inside hemodynamics laboratories.
Paraguay's health sector is undergoing a rapid modernization phase, propelled by joint initiatives of the Ministerio de Salud Pública y Bienestar Social (MSPBS) and the Instituto de Previsión Social (IPS). Historically, complex interventional procedures were concentrated heavily in the capital city of Asunción. Today, hospitals in Alto Paraná (Ciudad del Este) and Itapúa (Encarnación) are aggressively expanding their hemodynamics units to address the growing burden of cardiovascular diseases, which remain the leading cause of mortality in the country.
For local procurement entities, medical distributors, and hospital administrators, securing a reliable pipeline of high-quality diagnostic and therapeutic catheters is paramount. In particular, angiography catheters, which serve as the vascular conduit for radiopaque contrast agents and guide interventional equipment, must deliver exceptional mechanical performance.
Due to the structural constraints of regional healthcare budgets in South America, Paraguay's market demands a delicate balance: devices must deliver premium surgical accuracy matching European design paradigms while maintaining sustainable unit economics. High-performance catheters with high radiopacity, kink resistance, and torque transmission (1:1 control) minimize fluoroscopy and procedure times, protecting both patients and clinical staff from unnecessary radiation exposure.
Modern coronary and peripheral angiography demands specialized polymers and complex mechanical layups. At the core of our manufacturing processes at Zhejiang ZNG Medical is a commitment to advanced catheter architecture. Each catheter consists of three distinct layers integrated through co-extrusion and heat-reflow processes:
From preliminary configuration drawings to local shipping document verification, we manage the entire supply chain workflow with precision.
Analysis of customer specification drawings, dimensional tolerances, and mechanical requirements.
Preparation of unit cost structures, packaging options, and initial batch production estimates.
Fabrication of prototypes and clinical evaluation samples sent for testing confirmation.
Formal registration of Purchase Order details, quantities, and delivery milestones.
Issuing Proforma Invoice detailing commercial parameters and bank processing data.
Receipt of initial transaction deposit triggers production scheduling in cleanroom units.
High-precision medical grade extrusion, braiding, shaping, assembly and quality testing.
Visual validation records of manufacturing batches and package labels shared with clients.
Finalizing commercial balance transactions following successful quality control reports.
Scheduling air freight routes or ocean voyages destined for Paraguayan entry hubs.
Consignment dispatch to logistics companies with live location tracking features.
Dispatch of Bill of Lading (B/L), invoice, packing lists, and certificates for customs clearance.
Under strict compliance with medical manufacturing methodologies, our manufacturing floor houses cleanrooms and advanced quality check apparatus.
Established in 1996, Zhejiang ZNG Medical Co., Ltd. has grown to become a benchmark manufacturer of sterile medical consumables, leveraging advanced polymer extrusion and precision metal-tip sharpening machinery. With cleanrooms built to international standards, we execute rigorous quality control methodologies under ISO 9001 and CE frameworks to supply interventional radiology suites, hospitals, and primary health clinics around the globe.
Our Mission: ZNG Medical is firmly committed to addressing global healthcare and public health needs. By actively listening to clinical feedback from surgeons and procurement managers, we optimize current catheter profiles, develop specialized interventional shapes, and elevate overall patient safety levels.
Beyond our advanced angiography catheter series, our automated factory specializes in producing a comprehensive range of sterile medical needles and delivery vectors, including:
We also provide comprehensive injection mold design, mold fabrication, and automated assembly services to satisfy custom engineering requirements. Tell us your design parameters to start creating custom needle configurations.

One of the primary markers of clinical efficacy in hemodynamics is the ease of visibility of the catheter under fluoroscopy. ZNG Medical incorporates a specific concentration of Bismuth Subcarbonate and Tungsten inside the polyurethane raw materials of our outer jacket. This configuration offers clear visibility of the catheter body and distal tip, allowing surgical operators to verify the exact positioning within the coronary ostium or peripheral vasculature before injecting contrast.
Furthermore, catheter shape retention remains crucial. If a catheter loses its shape during a procedure due to body heat, the operator may find it difficult to cannulate the vessel, leading to prolonged vascular access times. We address this issue by thermal-setting the tips utilizing customized stainless-steel mandrels. Our Judkins (JL/JR), Amplatz (AL/AR), Pigtail, and Cobra (C2/C3) curves retain their structural memory even during extended diagnostic sessions, ensuring reliable vascular access.
Our catheter selection features optimized transition structures. The wall thickness transition from the rigid proximal segment to the extremely soft distal tip is engineered to prevent kinks. This design prevents catheter collapses under tension, offering smooth contrast media delivery.

Answers to technical, regulatory, and logistics queries for medical buyers in Paraguay.
Yes. We coordinate shipping logistics directly from our factories. We ship via ocean freight to the port of Villeta or San Antonio (using river barge connections via Buenos Aires or Montevideo ports), or via air freight directly to Silvio Pettirossi International Airport (ASU) in Luque/Asunción. We provide complete customs documentation, including B/L, Certificate of Origin, and packing lists.
We provide full regulatory support for your registration with the Dirección Nacional de Vigilancia Sanitaria (DINAVISA). Our document dossier includes CE certificates under MDR/MDD, ISO 13485 quality management certification, Certificates of Free Sale (FSC), biological safety validation data (ISO 10993), pyrogenicity evaluations, and EO sterilization validation records.
Yes. Zhejiang ZNG Medical offers comprehensive OEM/ODM customization. We can adjust the catheter shaft length (e.g., 65cm, 80cm, 100cm, 110cm, 125cm), modify the outer durometer configuration, and shape specialized tips like Cobra, Judkins, Amplatz, Pigtail, Multipurpose, or custom curves to match your clinical requirements.
Our hydrophilic coatings are applied using specialized UV curing chambers, ensuring a chemical bond with the catheter's outer jacket. We perform friction coefficient testing and durability testing to ensure the catheter maintains its lubricious state throughout vascular navigation, minimizing vessel irritation and vasospasms.
For standard configurations with existing mold shapes, the MOQ is low to support local clinical evaluations. For custom configurations, the MOQ varies depending on the extrusion setup and material requirements. Please contact our sales team with your specifications to receive a custom quote.
Standard production takes approximately 30 to 45 days after deposit confirmation and sample approval. Air cargo transit to Asunción takes 7 to 10 days, while ocean shipping to river ports near Asunción takes around 45 to 60 days. We provide updates at every stage of the shipment.
