Shenzhen, July 2, 2026 — Amisco Automation Components (Shenzhen) Co., Ltd., a wholly-owned subsidiary of Italy-based Amisco, a global leader in precision electromagnetic components, officially launched its fully mass-producible 5D (5DOF, 5 Degrees of Freedom) miniature medical magnetic positioning sensor. Drawing on over seven decades of accumulated expertise in micron-level coil winding technology and local dust-free intelligent manufacturing production lines in Shenzhen, the product achieves three major technological breakthroughs: submillimeter outer diameter, millimeter-level positioning accuracy, and biocompatible medical-grade encapsulation. It is fully compatible with minimally invasive devices including cardiac electrophysiology ablation systems, neurointerventional instruments, and magnetically navigated bronchoscopes. The sensor delivers a domestically mass-producible high-precision core magnetic navigation sensing solution for Chinese medical device manufacturers, effectively cutting radiation exposure during clinical operations and lowering barriers for device integration.
I. Industry Background: Explosive Growth of Magnetically Navigated Minimally Invasive Medicine, Miniature Sensors Become a Key Bottleneck Technology
Ionizing-radiation-free magnetically navigated surgery has emerged as a core development direction for interventional medicine in recent years. Compared with traditional DSA fluoroscopy, magnetic positioning technology outputs real-time 3D coordinates and posture angles of catheter tips, drastically reducing X-ray exposure for both physicians and patients. It serves as an essential core component for atrial fibrillation mapping and ablation, cerebral vascular intervention, and pulmonary nodule biopsy equipment.
The high-end miniature magnetic positioning sensor market has long been dominated by overseas manufacturers. Conventional sensors suffer from widespread pain points such as oversized outer diameters, weak anti-RF interference performance, incompatibility with ultra-fine catheters, and lengthy customized delivery cycles. As domestic electrophysiology and neurointerventional equipment undergo accelerated innovative iteration, new products including 3F/5F ultra-fine catheters, pulsed field ablation systems, and miniature magnetic navigation robots keep rolling out. The industry is in urgent need of local component suppliers capable of delivering miniaturized, high-precision, medically compliant sensors in mass quantities.
5 Degrees of Freedom (5D) magnetic positioning technology simultaneously outputs 3D spatial coordinates (X/Y/Z) as well as pitch and yaw angular posture data. It acts as a critical benchmark distinguishing basic positioning from high-end clinical navigation, directly determining tracking stability inside complex blood vessels and lumens as well as surgical safety.
II. Core Groundbreaking Technologies of Amisco 5D Magnetic Positioning Sensor
As a multinational enterprise with 70 years of experience in precision electromagnetic coil R&D and manufacturing, Amisco’s Italian headquarters R&D center has collaborated with its dedicated medical sensing laboratory in Shenzhen to overhaul the full-process manufacturing chain targeting clinical pain points in minimally invasive intervention. Its core technical advantages fall into four categories:
1.Ultra-fine Micron Winding Process for Ultimate Miniaturization Compatible with Thin Catheters Custom self-developed micro-winding equipment stably processes ultra-fine wires ranging from 0.008 mm to 0.2 mm in mass production, with winding tolerance controlled at ±2 μm. The minimum encapsulated outer diameter of finished sensors reaches 0.41 mm, perfectly fitting the inner lumens of 3F and 5F ultra-fine interventional catheters. This resolves the longstanding industry issue where bulky traditional sensors cannot access tiny distal blood vessels.
2.High-precision 5DOF Positioning for Stable Real-time Intraoperative Tracking Verified mass production specifications: spatial positioning error ≤ 1 mm, angular posture error ≤ 1°, with real-time pose data output at a high refresh rate of 20 Hz. The low-power coil design cuts power consumption by 60% compared with conventional alternatives, supporting synchronous parallel tracking of multiple probes and compatibility with all domestic and imported magnetic navigation host systems.
3.Full-process Medically Compliant Encapsulation for Short-term In-vivo Intervention The entire sensor adopts FDA implant-grade biocompatible transparent PI (polyimide) sleeves and high-temperature resistant insulating coatings, capable of withstanding disinfection at 200 °C. Compliant with the IEC60601 medical EMC standard, it boasts robust resistance to radiofrequency ablation interference and can be directly integrated with RF and pulsed field ablation catheters. Complete material biocompatibility reports are provided to support customers’ medical device registration applications.
4.Integrated OEM/ODM Customization to Shorten Equipment R&D Cycles The Shenzhen base delivers one-stop customized services covering magnetic cores, miniature coils, leads, medical encapsulation and signal matching. Parameters including winding turns, outer diameter and lead length can be adjusted to match customers’ catheter structures. Sample delivery takes only 7–15 days. An in-house comprehensive reliability laboratory conducts full testing including high/low temperature cycling, repeated bending, electromagnetic interference and biocompatibility, alongside complete technical documentation to facilitate registration and certification.
III. Full-scenario Clinical Applications Covering Major Minimally Invasive Interventional Tracks
Amisco 5D magnetic positioning sensors have been deployed in supporting clinical devices across four core segments:
- Cardiac Electrophysiology: 3D mapping catheters for atrial fibrillation, radiofrequency/pulsed field ablation catheters, and left atrial appendage occlusion navigation instruments, improving localization accuracy for complex arrhythmia lesions.
- Neurointervention: Cerebral vascular microcatheters, deep brain stimulation electrodes, and embolization guidewires for intracranial aneurysm navigation.
- Respiratory Intervention: Magnetically navigated bronchoscopes and miniature probes for pulmonary nodule biopsy, enabling radiation-free precise lung tissue sampling.
- General Minimally Invasive Tracks: Otolaryngology interventional instruments, gastrointestinal endoscopes, and terminal positioning sensing units for compact interventional surgical robots.
