    摘要： An interspinous process spacer and method of implanting same is provided for maintaining separation between adjacent spinous processes of adjacent vertebrae. The spacer has two lateral portions and a medial portion therebetween, the medial portion adapted to reside between the adjacent superior and inferior spinous processes in the deployed configuration to maintain separation therebetween. The lateral portions each comprise a superior lateral portion and an inferior lateral portion adapted to reside on the lateral side of the respective superior and inferior spinous process in the deployed configuration to maintain positioning of the interspinous process spacer between the two adjacent vertebrae. The lateral portions each comprise an expandable lateral member that is expandable from an insertion configuration to the deployed configuration, and at least one of the lateral portions includes within it a lateral support member configured to be deformable for the insertion configuration and expanded in the deployed configuration. The method includes introducing the spacer through a tubular delivery device to the region between the spinous processes and positioning therein, followed by retraction of the delivery device and expansion of the expandable lateral members and lateral support members.

    摘要翻译： 提供棘突间间隔和植入方法，以保持相邻椎骨的相邻棘突之间的分离。 间隔件具有两个横向部分和其间的中间部分，中间部分适于驻留在展开构造中的相邻上部和下部棘突之间，以保持它们之间的分离。 侧面部分各自包括优选的侧向部分和适于在展开构造中位于相应的上部和下部棘突的横向侧上的下侧部分，以保持棘突间间隔物在两个相邻椎骨之间的定位。 横向部分各自包括可膨胀的侧向构件，其可从插入构型扩展到展开构型，并且至少一个横向部分在其内部包括侧向支撑构件，该侧向支撑构件被构造成可变形以用于插入构造并且在展开构型中展开 。 该方法包括将间隔件通过管状输送装置引入棘突之间的区域并定位在其中，随后递送装置缩回和可膨胀侧向构件和横向支撑构件的膨胀。
