HyperSoft® Helical: Ultra-Soft Helical Finishing Coil for Final Aneurysm Void Filling
By Modern Medical Solutions Editorial Team
The HyperSoft® Helical from MicroVention Terumo is an ultra-soft helical bare-platinum finishing coil that complements the HyperSoft 3D by providing efficient filling of more uniform residual void geometries in cerebral aneurysm embolization, using a simple helix shape to achieve maximum coil density in the final packing phase.
What Is HyperSoft® Helical?
HyperSoft® Helical is the helical-shaped variant in MicroVention Terumo’s ultra-soft finishing coil family, used alongside HyperSoft 3D for the final packing phase of cerebral aneurysm embolization. The helical configuration provides a predictable, uniform coil shape that fills cylindrical or spherical residual void spaces efficiently — complementing the complex 3D shape of HyperSoft 3D, which is better suited for irregular or multi-lobed residual voids.
Like HyperSoft 3D, the Helical variant uses an ultra-soft platinum wire formulation with the lowest packing modulus in the MicroVention Terumo coil range. This ultra-low modulus means the coil can fill tight residual spaces between adjacent coil loops without building up tension that could compress the established framing basket or cause coil herniation into the parent artery.
Technical Specifications and Role
HyperSoft Helical is delivered via Headway 17 microcatheter and is available in a range of small diameters appropriate for final-phase filling. The helix geometry occupies a single plane within the deployed space, making the coil path predictable and the deployment mechanics consistent from case to case. The ultra-soft platinum wire is the same formulation as HyperSoft 3D.
The practical difference between HyperSoft 3D and HyperSoft Helical is in the shape of the residual void being filled: choose HyperSoft 3D for irregular, asymmetric, or multi-lobed voids where a three-dimensional shape provides better void coverage; choose HyperSoft Helical for more symmetric, roughly spherical or cylindrical residual voids where a helical coil fills the space efficiently and predictably.
Clinical Applications
HyperSoft Helical is used in the final phase of aneurysm coiling after framing, secondary framing, and bulk filling are complete. It is the preferred finishing coil when the remaining residual void is roughly spherical or cylindrical, as the helical geometry maps naturally to these void shapes. For larger spherical final voids, a HyperSoft 3D may be used first, followed by Helical for the last remaining space.
In very small aneurysms (3–5 mm) where the entire embolization is performed with small-calibre coils, HyperSoft Helical may be used as the final one or two coils after a Cosmos 10 framing sequence, adding the final volume without the risk of overloading the small sac with a complex 3D shape.
Technique Tips
The helical geometry of HyperSoft Helical creates a predictable coil path during deployment — once the first loop is established in the residual space, subsequent loops will stack in a consistent helical pattern. Use this predictability to anticipate the coil path and stop deployment when the loop count matches the estimated remaining void volume.
If the HyperSoft Helical deploys with immediately high resistance, the void is too small for the selected coil diameter. Switch to a one-size-smaller HyperSoft Helical rather than pushing through the resistance, which risks microcoil fracture in the ultra-soft wire.
