可膨胀椎间植入物及其使用方法
摘要：
一种椎间植入物，包括第一部件和第二部件。第二部件包括致动件，第三部件包括第一斜部和与第一斜部轴向间隔开的第二斜部。第三部件包括多个导轨，这些导轨包括各斜部的至少一部分。设置有第一导轨的斜部的部分中的至少一个具有第一高度，而设置有第二导轨的斜部的部分中的至少一个具有第二高度。第一高度大于所述第二高度。致动件能够与第三部件接合，以实现轴向平移，使得在第一构造和第二构造之间所述斜部接合至少一个部件。公开了使用的方法。
摘要（英）：

An intervertebral implant comprises a first component and a second component. The second component includes an actuator and a third component comprises a first ramp and a second ramp axially spaced apart from the first ramp. The third component comprises rails including at least a portion of the ramps. At least one of the ramp portions disposed with the first rail has a first height and at least one of the ramp portions disposed with the second rail has a second height. The first height is greater than the second height. The actuator is engageable with the third component to effect axial translation such that the ramps engage at least one of the components between a first configuration and a second configuration. Methods of use are disclosed.
