HyperSoft® 3D: Ultra-Soft Three-Dimensional Finishing Coil for Final Aneurysm Packing

HyperSoft® 3D is MicroVention Terumo’s ultra-soft finishing coil, representing the softest platinum coil in the MicroVention Terumo portfolio by packing modulus. The three-dimensional complex coil geometry allows HyperSoft 3D to conform to irregular, asymmetric, and multi-lobed residual void spaces within the aneurysm sac that simpler helical coils cannot fill efficiently. The ultra-low packing modulus means the coil exerts almost no outward force on the aneurysm wall or on previously placed coils, making it exceptionally safe to deploy as the final coil in a dense packing sequence.

The clinical role of HyperSoft 3D is exclusively in the finishing phase: after framing is complete (Cosmos 18 or HydroFrame 18), secondary framing (HydroFrame), and bulk filling (VFC or Cosmos 10), HyperSoft 3D is used to fill the last small irregular voids that remain. Its three-dimensional shape adapts to these voids precisely, maximising the final packing density achieved before the procedure is concluded.

HyperSoft 3D is available in a range of small diameters and lengths appropriate for finishing-phase deployment, where the remaining void spaces are smaller than the initial framing and bulk-filling phases. It is delivered via Headway 17 microcatheter. The ultra-soft platinum wire formulation is a distinct alloy from the Cosmos and VFC lines, calibrated to achieve the minimum packing modulus while maintaining sufficient structural integrity to hold its three-dimensional shape after deployment.

The 3D designation refers to the complex three-dimensional configuration of the deployed coil, which creates multiple contact points with adjacent coil loops and aneurysm wall in different planes. This multi-plane contact is the mechanism by which HyperSoft 3D fills irregular voids more completely than a helical coil, which occupies a single plane.

HyperSoft 3D is the final coil in a multi-coil embolization protocol. It should not be used for framing or bulk filling, as its ultra-soft modulus makes it unsuitable for creating or reinforcing a basket structure. Its role is specifically to fill the last irregular residual voids after all framing and bulk filling is complete.

In complex multi-lobed or irregularly shaped aneurysms where the framing basket has geometric irregularities matching the aneurysm morphology, HyperSoft 3D is particularly effective because its 3D shape adapts to irregular three-dimensional void spaces that a helical coil would leave partially unfilled. Post-procedure angiography should be performed with the HyperSoft 3D in place after 10 minutes to allow any HydroSoft or HydroFrame coils in the sac to reach full swelling before assessing final occlusion grade.

Introduce HyperSoft 3D only when the preceding coil fills with moderate resistance — indicating that the remaining space is small enough that the ultra-soft 3D coil will achieve dense contact. If the preceding coil fills freely with no resistance, the space is still large enough for a larger-diameter coil before switching to HyperSoft 3D.

Deploy HyperSoft 3D very slowly to allow the 3D shape to unfurl within the residual void space. The ultra-soft wire will not push against resistance — if deployment resistance is encountered early, the 3D coil is too large for the remaining space and a smaller diameter should be selected.
