InterMag

What InterMag does

InterMag Inc., founded in 2008 and headquartered in Seoul, South Korea, is a privately held medical device company that develops magnetically navigated micro-robot and catheter systems for endovascular intervention and capsule endoscopy. Its core platform is the RAMAN (Robotically Assisted MAgnetic Navigation) system, which generates external magnetic fields (electromagnetic coils or permanent magnets) to remotely steer micro-robots and the distal ends of magnetic catheters or guidewires. The portfolio splits into two clinical product lines: the I-RAMAN System for endovascular intervention (targeting occlusive vascular disease treatment) and the C-RAMAN System for capsule endoscopy of the upper gastrointestinal tract, along with Feeding Robot, Micro-robot Type A (≤3 Fr), Micro-robot Type B (6-7 Fr), and a 3D Vascular Mapping Technology. Notable technical components include 8 electromagnetic coils generating a 110 mT ultra-strong magnetic field, a 7 DoF robot stage, X-ray machine compatibility, and modular architecture allowing use of conventional catheters and guidewires.

The company operates an enterprise field-sales go-to-market targeting hospitals and healthcare institutions directly, with clinical validation conducted through partnerships with Korean university hospitals including Hanyang University Hospital and Dongguk University Hospital. Revenue model is hardware sales of capital medical equipment (navigation systems, micro-robots, feeding robots) with quote-based enterprise pricing; revenue figures are not publicly disclosed. Manufacturing is supported by 2024 GMP certification, and the exploratory clinical trial plan for the magnetic navigation system and feeding robot was approved in 2024, indicating transition toward commercialization. Component manufacturing partnerships with CV Bio (peripheral guiding catheters and stents), OSY med (3Fr micro-catheters), and Intromedic (capsule endoscope with global sales network) anchor the supply chain, and selection into the MedTech Innovator Asia Pacific Accelerator 2024 provides visibility and potential non-dilutive funding. Founded by Gunhee Jang, Distinguished Professor at Hanyang University, the company has built its technology base on 16 years of university-led research with publications in IEEE Transactions journals (Mechatronics, Industrial Electronics).

Core offering

InterMag manufactures and sells the RAMAN (Robotically Assisted MAgnetic Navigation) platform of medical devices for hospitals and healthcare institutions. The I-RAMAN System enables remote, X-ray radiation-free endovascular intervention by controlling external magnetic fields to steer micro-robots and magnetic catheters/guidewires, while the C-RAMAN System performs automated capsule endoscopy of the upper gastrointestinal tract using dual permanent magnet control. Supporting components include the Magnetic Navigation System (MNS), Feeding Robot, Micro-robot Type A (3 Fr), Micro-robot Type B (6-7 Fr), and Guiding Catheter.

Product overview

InterMag develops the RAMAN (Robotically Assisted MAgnetic Navigation System) platform consisting of two main product lines: I-RAMAN for endovascular intervention and C-RAMAN for capsule endoscopy. The I-RAMAN System provides magnetic navigation for vascular procedures with a core Magnetic Navigation System (MNS), Feeding Robot, and Micro-robots (Type A and Type B) that enable remote control of catheters and guidewires without X-ray radiation exposure. The C-RAMAN System provides full-automatic magnetic navigation for capsule endoscopy to examine the GI tract. Both systems use external magnetic fields generated by electromagnets or permanent magnets to control magnetic medical devices, offering a modular platform architecture where the navigation system serves as the core component and specialized robots provide therapeutic and delivery functions.

Expansion highlights6 records

Broad incumbents

• Medtronic: Diversified medical device leader with major franchises in interventional cardiology (including the Hugo robotic-assisted surgery system) and endoscopy. Operates in both core target markets of InterMag with deeper regulatory and commercial infrastructure.
• Olympus: Global leader in endoscopic imaging systems and therapeutic endoscopy devices. Comparable to the C-RAMAN side of InterMag, although Olympus's portfolio does not currently include magnetically steered capsule endoscopy.
• Intuitive Surgical: Dominant surgical robotics company (da Vinci, Ion) with broad minimally invasive surgery and image-guided bronchoscopy platforms. Comparable as a medical robotics incumbent that increasingly competes in catheter/endoluminal procedures adjacent to InterMag's I-RAMAN.
• Boston Scientific: Major player in endoscopy, interventional cardiology, and peripheral vascular devices. Relevant because its existing cardiology, endovascular, and endoscopy franchises overlap with InterMag's I-RAMAN and C-RAMAN target markets.
• Johnson & Johnson (Auris Health / Monarch): Through Auris Health's Monarch platform, J&J offers robotic bronchoscopy; broadly applies robotic endoluminal navigation to lung procedures, a closely adjacent indication family to InterMag's GI capsule and endovascular interventions.

Direct peers

• Stereotaxis: US-listed developer of magnetic navigation systems (Niobe/Genesis) for cardiac ablation and endovascular procedures. Directly comparable because both companies use externally generated magnetic fields to steer interventional devices inside the body.
• CapsoVision: Developer of CapsoCam, a small-bowel capsule endoscopy system. Competes with InterMag in the capsule endoscopy space, albeit without magnetic steering, but targets the same gastroenterology use case.
• Microbot Medical: Israel-based company developing the LIBERTY endovascular robotic system and self-disaggregating micro-robots for neurovascular and peripheral vascular interventions. Directly overlaps InterMag on remotely controlled micro-robots for endovascular use.
• AnX Robotica: Developer of magnetically controlled capsule endoscopy systems (Navicam) for GI examination. Directly comparable to InterMag's C-RAMAN product line, both relying on external magnets to maneuver capsule endoscopes through the GI tract.

Others

• Hanyang University Medical Center / Korean hospital networks: InterMag's clinical R&D partners (Hanyang University Hospital and Dongguk University Hospital). They are not commercial peers but represent the hospital-side ecosystem where comparable clinical validation studies for magnetic navigation and capsule endoscopy occur.
