Introduction/Purpose The Kaneka i-ED coil system offers 5 coil types of varying softness (standard, medium, soft, extra soft, and silky soft) and 3 different shapes from low-memory to a high-volumetric filling coil (i-ED Complex coil, i-ED Complex-Infini coil and i-ED 14-Infini). Some of the coils can be delivered and detached through a 0.013-inch microcatheter. The monopolar detachment system indicates with a light and sound signal when the best detachment position for the coil is reached, eliminating the need for a 2-marker microcatheter. We here present our initial experience with use of the Kaneka coils for treatment of intracranial aneurysms.

Materials and Methods We reviewed our neurointerventional database and identified all patients who underwent coil embolization for intracranial aneurysm treatment Between January and February 2023. We then reviewed the procedural data and included all patients in whom Kaneka i-ED coils were used. Patient characteristics and procedural data were collected.

Results The Kaneka i-ED coils were used in 4 patients (1 female) with mean age of 65 years (range 49 - 69 years). The aneurysms were unruptured and located at the MCA bifurcation (n=2), anterior communicating artery (n=1) and basilar tip (n=1). Mean largest aneurysm diameter was 4.2 mm (range 3.3 mm to 5.8 mm). Two aneurysms were previously treated (Y-stent coil and coiling) requiring re-treatment. Y-stenting in combination with Kaneka coils was performed in one case given the wide neck of the aneurysm. Coil systems used included the Complex SilkySoft coils in 3 cases and Complex Infini coil in 1 case. All coils were delivered and deployed with a Headway Duo microcatheter (Microvention) either 156 cm length with 2 marker tips or 167 cm length with 1 marker tip. Coil deployment and detachment was successful in all cases. In previously treated cases, the coils found open space within the aneurysm without moving/dislodging existing coil loops.

Conclusion The Kaneka i-ED coil system offers a versatile portfolio of different coil types, lengths, and profiles to treat and re-treat a large variety of intracranial aneurysms. Our initial experience with these coils has been very promising. Patient follow-up and additional cases are needed to further evaluate this new coil system.
