Abstract:
A system for forming an implant to stabilize an interior of a vertebral body is provided. The system includes a delivery cannula. A plurality of elements are disposed adjacent to one another in the delivery cannula with void spaces defined between the elements. A fluent material, capable of setting to a hardened condition, is disposed within at least a portion of the void space in the delivery cannula. A push rod is movably disposed within the delivery cannula to apply a force to move the elements through the delivery cannula and into the interior of the vertebral body. Upon application of the force, the elements simultaneously carry the fluent material through the delivery cannula and into vertebral body to delivery the fluent material at a low pressure. The fluent material sets to the hardened condition to secure the elements and form the implant.
