SPASY™ — Vertebral augmentation system for compression fractures (VCF)

SPASY™ is a complete cement vertebral augmentation system, developed by Seawon Meditech for the minimally invasive treatment of vertebral compression fractures (VCF). The system covers both common percutaneous techniques — balloon kyphoplasty (for restoring vertebral body height and creating a cavity) and vertebroplasty (bone cement injection) — through dedicated kits, assemblable for one or two levels.

The kyphoplasty component (SPASY™ Spinal Alignment System) comprises a balloon catheter available in three sizes (SWS10 / SWS15 / SWS20, with lengths of 10 / 15 / 20 mm and maximum volumes of 4–6 cm³), an inflation device (Balloon Expander, SWMP) with a manometer that indicates the balloon pressure, a release button, and a Lock/Unlock mechanism, plus the complete bone access set: a puncture needle (Bone Marrow Needle, SWMVP, with a slant, beveled, or trocar tip), a guide wire (SWM-1), a working cannula and trocar (SWM-2), a bone drill (SWM-3), and the cement filling device (SWM-4). The technique follows the standard steps: transpedicular access, cavity creation, balloon inflation under fluoroscopic control (C-arm), and cement injection.

The vertebroplasty component (SPASY™ Bone Cement Dispensing Kit) uses a cement dispensing device (SWDG-4A) with a piston, a push handle, and a trigger for fine control of the injection, fed through a hose from the bone access needle available in 11G and 13G (SWVP-11A / SWVP-13A, 125 mm length). The system is intended for vertebral compression fractures of osteoporotic, osteolytic, or metastatic origin.

• Vertebral compression fractures (VCF) of osteoporotic origin.
• Osteolytic fractures of the vertebral body.
• Metastatic (tumor) vertebral fractures.
