The Terumo Neuro HydroFrame 18 Coil (REF 181850HFRM-V) is a hydrogel-coated framing coil engineered for endovascular embolization of intracranial aneurysms and other neurovascular lesions. With a 18 mm primary diameter and 50 cm working length, this 0.018 in class framing coil is designed to establish a stable basket within the aneurysm sac, supporting subsequent filling and finishing steps.

Key Features
Hydrogel-coated platinum coil platform that expands after deployment to increase volumetric filling versus bare platinum.
Framing geometry intended to conform to the aneurysm wall and create a stable scaffold for follow-on coils.
0.018 in coil class compatible with commonly used neurovascular microcatheters with a 0.0165 in or larger inner lumen (verify with the microcatheter IFU).
Detachment via the manufacturer's electrolytic / mechanical detachment system as specified in the current IFU.
Supplied sterile for single use in a protective introducer hoop.

Clinical Applications
Endovascular embolization of intracranial saccular aneurysms.
Framing of large and wide-necked aneurysms where enhanced volumetric occlusion is desired.
Embolization of other peripheral neurovascular lesions when deemed appropriate by the treating physician, in accordance with the product IFU.
