Scepter™ C Balloon Microcatheter: Compliant Intracranial Balloon for Remodelling, PHIL Delivery, and Test Occlusion
Автор: Modern Medical Solutions Editorial Team
The Scepter™ C from MicroVention Terumo is a compliant dual-lumen balloon microcatheter with a 0.027 in working lumen in 4 mm and 7 mm diameters, used for balloon-assisted coil embolization of wide-neck aneurysms, selective vessel flow arrest during PHIL liquid embolic delivery, and intracranial test occlusion procedures.
What Is Scepter™ C?
The Scepter™ C is a compliant dual-lumen balloon microcatheter from MicroVention Terumo whose dual-lumen architecture — a central 0.027 in working channel running coaxially through the balloon catheter — keeps the working channel patent during balloon inflation. This allows contrast injection, guidewire navigation, or device delivery while the balloon is simultaneously inflated, enabling real-time angiographic assessment of occlusion completeness without deflating the balloon.
Catalog: SC4x11 (4 mm balloon, 11 mm length), SC4x20 (4 mm, 20 mm), SC7x20 (7 mm, 20 mm). The 4 mm variants serve MCA M1, basilar artery, and posterior circulation vessels; the 7 mm variant covers the supraclinoid ICA and proximal basilar trunk. The compliant balloon conforms to a range of vessel diameters with controlled fill volumes.
Three Clinical Roles
Balloon-assisted coil embolization: Scepter C is positioned across the aneurysm neck in the parent artery. The balloon is inflated during each coil delivery to prevent herniation, then deflated between deliveries. Higher packing densities are achievable than with primary coiling, without DAPT. Preferred for ruptured aneurysms, patients with high bleeding risk, and those requiring early surgery.
PHIL liquid embolic delivery: Scepter C is positioned proximal to the target AVM feeding pedicle and inflated to arrest flow during PHIL injection, preventing proximal reflux. The working lumen carries the Headway DUO to the target territory. Test occlusion: the 0.027 in working lumen allows continuous angiographic monitoring of intracranial perfusion while the balloon is inflated, without needing balloon deflation for each run.
Scepter™ C vs. Scepter XC and BOBBY
Scepter C provides reliable occlusion at characterised fill volumes for vessels with well-defined diameters — it is the first choice for straightforward wide-neck aneurysm neck remodelling. Scepter XC is preferred for wider-neck geometries spanning variable vessel diameters where the extra compliance bridges a broader range. BOBBY is an alternative balloon remodelling catheter within the MicroVention Terumo portfolio; operators should choose based on balloon compliance match to their anatomy and personal preference.
The Scepter C’s dual-lumen contrast injection capability during inflation distinguishes it from single-lumen competitors (HyperGlide, HyperForm) by enabling simultaneous angiographic assessment without balloon deflation.
Technique Tips
Inflate Scepter C slowly using dilute contrast (1:4 contrast:saline) for fluoroscopic visualisation. Stop at the first sign of complete vessel occlusion on road-map — do not inflate to a preset volume. Deflate the balloon between coil deliveries to allow brief flow restoration and assessment.
For PHIL delivery: pre-inflate to arrest flow, inject PHIL through the coaxially positioned Headway DUO under continuous fluoroscopy. Stop injection if PHIL approaches the balloon face. Wait 60–90 seconds after injection before deflating to allow the cast to solidify proximally.
