    • A bone filler material delivery system comprising a longitudinal channel, wherein said channel incorporates a perforated segment at least partially along, at or substantially near its distal end, and wherein said channel is sealed at its distal end so the filler material may be delivered only by the lumen and through the perforated segment peripheral wall/s. Optionally, said system comprising an expandable-collapsible permeable bag capable of being inserted into a bone while in collapsed configuration and then to expand within the bone when filled with bone voids filler. The mesh structure is designed to allow such permeable bag to expand to a predetermined size or shape under certain pressures, and further allows exudation of said bone void filler through its walls. One satisfactory result is achieved by extracting the permeable bag out of treated body, thus promoting a flow of the bone void filler through its pores into the cancellous bone and/or cavity in the bone. The procedure described promotes height restoration of the bone while leaving only filler material inside the body, while introducing it in an enhanced controlled manner.
    • 一种骨填料输送系统,其包括纵向通道,其中所述通道至少部分地沿其远端处或远近远端结合穿孔段,并且其中所述通道在其远端处被密封,使得填充材料可以仅由 内腔和穿孔段周边壁。 任选地,所述系统包括可膨胀的可收缩的可渗透袋,其能够在塌陷构型时插入骨骼中,然后在充满骨空隙填充物时在骨内膨胀。 网状结构被设计成允许这种可渗透袋在一定压力下膨胀到预定尺寸或形状,并且还允许所述骨空隙填料通过其壁渗出。 通过将可渗透袋从处理体中提取,从而促进骨空隙填料通过其孔进入松质骨和/或骨中的空腔而实现令人满意的结果。 所描述的方法促进了骨骼的高度恢复,同时在体内只留下填充材料,同时以增强的受控方式引入。
