What Terumo Neuro does

Terumo Neuro (formerly MicroVention) is a neurovascular medical device company headquartered in Aliso Viejo, California, and a wholly-owned subsidiary of Terumo Corporation (TSE:4543), the Japanese medical technology group founded in 1921. Operating as the Neurovascular Division within Terumo's Cardiac and Vascular Company, the company develops and commercializes endovascular devices used to treat hemorrhagic stroke (intracranial aneurysms, AVMs, dAVFs) and ischemic stroke (large vessel occlusion, carotid disease). Its product portfolio spans two categories — therapeutic devices and access products — covering the full procedural workflow from guidewire navigation through coil embolization, flow diversion, liquid embolization, and mechanical thrombectomy.

The core technology base includes proprietary platforms such as the HydroCoil hydrogel embolic system, the WovenEndoBridge (WEB) intrasaccular embolization device, FRED and CASPER flow diverters, the PHIL liquid embolic system, the SOFIA aspiration catheter family, the ERIC stent retriever, the BOBBY balloon guide catheter, and a broad microcatheter/guidewire access portfolio (Headway, Scepter, Traxcess, Chaperon). These devices are backed by an extensive clinical evidence program of more than 50 studies and a deep US patent portfolio covering each product family. Manufacturing occurs at the Aliso Viejo innovation center and at a dedicated facility in Costa Rica (Zona Franca Coyol).

The business model is direct enterprise hardware sales to hospitals, stroke centers, and neurosurgeons, with regional commercial offices in North America, EMEA (France, Germany, Italy, UK, Switzerland), China/APAC, and LATAM. Products are quote-based, ordered by phone, fax, or direct sales contact, and delivered through the company's own field sales and customer service teams. The company also reaches physicians through medical conferences (ESMINT, SVIN, SNIS, WSC), clinical education content, and a dedicated clinical studies platform launched in June 2026. Terumo Corporation's footprint across 160+ countries provides distribution and capital backing.

Core offering

Terumo Neuro develops and manufactures endovascular medical devices for the treatment of hemorrhagic and ischemic stroke, including embolization coils (HES/HydroCoil family), intrasaccular devices (WEB/WovenEndoBridge), flow diverters (FRED, CASPER), liquid embolics (PHIL), aspiration catheters (SOFIA), stent retrievers (ERIC), balloon guide catheters (BOBBY), and access products (microcatheters, guidewires, guiding catheters). These devices are sold to hospitals and neurointerventionalists for the treatment of intracranial aneurysms, arteriovenous malformations, and acute ischemic stroke caused by large vessel occlusion.

Product overview

Terumo Neuro (formerly MicroVention) develops a comprehensive portfolio of medical devices for the endovascular treatment of neurovascular diseases, primarily hemorrhagic and ischemic stroke. The portfolio is organized across two disease categories — Hemorrhagic (including intracranial aneurysms and neurovascular malformations) and Ischemic (including acute ischemic stroke and carotid artery disease) — and two solution types: Therapeutic devices and Access products. The therapeutic hemorrhagic portfolio includes the HES™ Coil family (HydroCoil, HydroSoft, HydroSoft 3D, HydroFrame, HyperSoft 3D/Helical, Complex coils), the WEB™ Intrasaccular Embolization System including WovenEndoBridge™ 17, the PHIL™ Liquid Embolic System, and flow diverters (FRED™/FRED Jr./FRED X, CASPER™). The therapeutic ischemic portfolio includes SOFIA™ Aspiration Catheter family (SOFIA, SOFIA EX, SOFIA Flow 88, SOFIA Flow Plus), the BOBBY™ Balloon Guide Catheter, and the ERIC™ Stent Retriever. Access products include Headway™ Microcatheters (including Headway Duo), Chaperon™ Guiding Catheters, Scepter™ C/XC/Mini Balloon Microcatheters, Traxcess™ Guidewires (including Traxcess Mini), VIA™ Microcatheter, WEDGE™ Delivery Catheter, and aspiration accessory kits. LVIS™/LVIS Jr./LVIS EVO™ Coil Assist Stents bridge both therapeutic categories. The company operates globally with manufacturing in Costa Rica and headquarters in Aliso Viejo, California, and is a subsidiary of Terumo Corporation.

Products and services

• HES Coil (HydroCoil Embolic System) A hydrogel-based embolic coil system for the endovascular treatment of intracranial aneurysms. The HES family includes HydroCoil, HydroSoft, HydroSoft 3D, HydroFrame, HyperSoft 3D, HyperSoft Helical, and Complex coil variants. Hydrogel-coated coils swell on contact with blood to promote aneurysm occlusion. Used by neurointerventionalists for treating ruptured and unruptured aneurysms. Demonstrated 4.4% aneurysm recurrence rate vs 15.4% with bare platinum coils.
• WEB Embolization System (WovenEndoBridge) An intrasaccular aneurysm embolization device placed within the aneurysm sac to achieve occlusion. Includes WEB-SL and WEB-SLS variants. Used for both ruptured and unruptured aneurysms. The WovenEndoBridge 17 variant received regulatory approval in Japan in May 2026. Backed by more than 15 years of clinical evidence.
• FRED Flow Diverter (and FRED Jr., FRED X) A self-expanding flow diversion stent placed across the neck of an intracranial aneurysm to redirect blood flow and promote aneurysm occlusion. FRED Jr. is a smaller version for smaller vessels; FRED X is a newer variant. Used by neurointerventionalists for intracranial aneurysm treatment.
• LVIS Coil Assist Stent (and LVIS Jr., LVIS EVO) A low-profile visualized intraluminal support stent used to assist coil embolization of intracranial aneurysms by providing scaffolding to prevent coil migration. LVIS Jr. is a smaller-profile variant; LVIS EVO is a newer iteration.
• PHIL Liquid Embolic System A liquid embolic agent injected into abnormal blood vessels to embolize (occlude) them from within. Used for the endovascular treatment of intracranial dural arteriovenous fistulas (dAVFs) and other vascular malformations. Demonstrated 86.9% complete angiographic cure rate for dAVF treatment.
• CASPER Flow Diverter A flow diversion stent designed to treat intracranial aneurysms by diverting blood flow away from the aneurysm sac.
• SOFIA Aspiration Catheter (SOFIA, SOFIA EX, SOFIA Flow, SOFIA Flow Plus, SOFIA Flow 88) A family of intermediate/aspiration catheters designed for use in mechanical thrombectomy to remove blood clots from cerebral arteries in acute ischemic stroke patients. Includes SOFIA (standard), SOFIA EX, SOFIA Flow 88, and SOFIA Flow Plus variants. Demonstrated 97.2% mTICI≥2b recanalization rate as first-line aspiration therapy.
• BOBBY Balloon Guide Catheter A balloon guide catheter used in mechanical thrombectomy procedures for acute ischemic stroke. The balloon inflates to temporarily halt blood flow and stabilize the catheter during clot retrieval.
• ERIC Stent Retriever A stent-based clot retrieval device deployed across an intracranial occlusion to engage and retrieve the thrombus in acute ischemic stroke mechanical thrombectomy procedures.
• Headway Microcatheters (including Headway Duo) Microcatheters used to navigate the neurovascular anatomy to deliver therapeutic devices (coils, stents, flow diverters) to target lesions. Includes Headway Duo variant for dual-lumen applications.
• Chaperon Guiding Catheters Large-bore guiding catheters that provide stable access and support within the neurovascular system during interventional procedures.
• Scepter Balloon Microcatheters (Scepter C, Scepter XC, Scepter Mini) Dual-lumen balloon microcatheters that enable balloon inflation for vessel remodeling or protection during coil or liquid embolic delivery. Scepter C and XC are standard variants; Scepter Mini is a lower-profile version.
• Traxcess Guidewires (including Traxcess Mini) Neurovascular guidewires designed to navigate tortuous intracranial vessels to reach target lesions. Traxcess Mini is a smaller-profile variant.
• VIA Microcatheter A microcatheter used for device delivery in neurovascular interventions.
• WEDGE Delivery Catheter A delivery catheter designed to facilitate the placement of therapeutic devices in the neurovascular system.
• EmPro Embolic Protection Device An embolic protection device used during neurovascular procedures to prevent the migration of embolic material.
• Aspiration Syringe Kit and Aspiration Tubing Kit Aspiration accessories used during endovascular procedures to apply suction for clot removal or vessel preparation.
