    • Apparatus and methods are provided for treating sleep apnea, snoring, and the like using an implant within an oropharyngeal region adjacent an anterior longitudinal ligament. The implant includes an endless loop defining a curved central region between first and second regions in a horizontal plane. The central region is vertically narrow relative to the first and second regions, and the first and second regions are compressible vertically to allow the first region to be directed through or behind the ligament adjacent the oropharyngeal region such that the central region is disposed within or behind the ligament. The first region is resiliently expandable after passing through or behind the ligament to contact tissue adjacent the oropharyngeal region. The first and second regions are compressible into a “C” shape within the horizontal plane, yet biased to expand and apply a force to dilate the tissue adjacent the oropharyngeal region.
    • 提供了使用邻近前纵韧带的口咽部区域内的植入物来治疗睡眠呼吸暂停,打鼾等的装置和方法。 植入物包括在水平面中限定第一和第二区域之间的弯曲中心区域的无限循环。 中心区域相对于第一和第二区域是垂直窄的,并且第一和第二区域是可垂直压缩的,以允许第一区域被引导通过毗邻口咽区域的韧带中或后面,使得中心区域位于或后面 韧带。 第一区域在通过或穿过韧带后可弹性膨胀以接触邻近口咽区域的组织。 第一和第二区域在水平面内可压缩成“C”形,但是被偏压以膨胀并且施加力以扩张毗邻口咽部区域的组织。

    • An apparatus and method for removing intervertebral disc material, particularly nucleus pulposus, from a patient is provided. The apparatus generally includes a handpiece and a tissue removal mechanism connected thereto. The tissue removal mechanism includes a cannula adapted to be inserted into an intervertebral disc and having an open distal tip and an outer diameter of less than about 5 mm, or less than about 2 mm. The mechanism further includes a rotatable element having a distal portion with helical threading. The distal portion of the rotatable element extends beyond the open distal tip of the cannula in order to allow tissue to prolapse between turns of the helical threading. The apparatus is designed to aspirate nucleus pulposus into the cannula upon rotation of the rotatable element and without the need for supplemental sources of aspiration. The invention further provides a method for monitoring intervertebral disc pressure before, during and/or after a treatment procedure.
    • 提供了一种用于从患者中去除椎间盘材料,特别是髓核的装置和方法。 该装置通常包括与其连接的手持件和组织移除机构。 组织移除机构包括适于插入椎间盘并且具有小于约5mm或小于约2mm的开放远侧末端和外径的套管。 该机构还包括具有螺旋螺纹的远侧部分的可旋转元件。 可旋转元件的远端部分延伸超过套管的开放的远侧末端,以便允许组织在螺旋螺纹的转动之间脱垂。 该装置设计成在旋转元件旋转时将髓核吸入套管中,而不需要补充吸入源。 本发明还提供了一种用于在治疗过程之前,期间和/或之后监测椎间盘压力的方法。
