DirectInject is a self-setting, calcium phosphate cement intended to repair neurosurgical burr holes, contiguous craniotomy cuts and other cranial defects not intrinsic to the stability of the bony structure. It is also intended for augmentation or restoration of bony contour in the craniofacial skeleton to include the cranial and zygomatic bones. DirectInject is intended to repair cranial defects with a surface area of 4 sq-cm or less. DirectInject is indicated for patients in whom skeletal growth is complete. It can be used in patients with surgically created bone defects. DirectInject is provided pre-filled in a double barrel delivery syringe system. Inside the delivery syringe are two pastes that are injected through a mixer-cannula which forms a homogenous cement. A second mixer-cannula is provided to give you the flexibility to pause implantation while you address other surgical needs.
