    • Apparatus is provided, including a locking mechanism, an implant, and a flexible strip within the implant having a plurality of recesses. A perimeter of the strip shortens and expands when the first end of the strip is advanced bidirectionally with respect to a second end of the strip. The locking mechanism includes a moveable recess-engaging portion, a mechanical support removably coupled to the recess-engaging portion, and a force applicator which maintains the recess-engaging portion in a position in which the recess-engaging portion is not disposed in any of the recesses. Upon decoupling of the mechanical support from the recess-engaging portion, the force applicator restricts motion of the plurality of recesses of the strip with respect to the second end of the strip, by facilitating positioning of the recess-engaging portion in one of the plurality of recesses. Other embodiments are also described.
    • 提供了包括锁定机构,植入物和在植入体内的具有多个凹部的柔性条带的装置。 当带的第一端相对于带的第二端双向前进时,带的周边缩短并膨胀。 锁定机构包括可移动的凹入接合部分,可移除地联接到凹部接合部分的机械支撑件,以及将凹部接合部分保持在凹部接合部分不设置在凹部接合部分中的任一个 凹槽。 在机械支撑件与凹陷接合部分分离时,力施加器通过促进凹部接合部分在多个部分之一中的定位来限制条带的多个凹部相对于条带的第二端的运动 的凹陷。 还描述了其它实施例。
