摘要：
An expandable intervertebral implant, including a superior and inferior members configured to engage a superior and inferior intervertebral body, and an expansion mechanism disposed between the members to selectively adjust separation between them. The expansion mechanism includes a proximal wedge structure and a distal wedge structure that are relatively translated between the superior and inferior members. The wedge structures are coupled to the superior and inferior members by a plurality of track structures and rail structures. The superior and inferior members are configured to mate vertically when the expansion mechanism is undeployed via conformal protruding and recessed features.
摘要（中）：
一种可扩展的椎间植入物，包括构造成接合上下椎间体的上下构件，以及设置在构件之间的膨胀机构，以选择性地调节它们之间的间隔。 膨胀机构包括在上部和下部构件之间相对平移的近端楔形结构和远侧楔形结构。 楔形结构通过多个轨道结构和轨道结构联接到上部和下部构件。 上下构件在膨胀机构通过共形凸出和凹陷特征取消部署时垂直配合。
