摘要： A cranial bolt secured to a skull of a patient includes a threaded portion and a lumen portion. Threaded portion has an inner surface forming a central passageway which extends throughout the threaded portion. The inner surface includes a connector mating with the lumen portion. The lumen portion includes a stem portion that enters the central passageway and engages the mating connector. A fluid tight seal is formed between the inner surface of the threaded portion and the stem portion. At least two lumens are disposed through the stem portion and the base portion. The lumens have a proximal end opening outside the skull and a distal end opening inside the skull. One embodiment includes sensor lumens diverging from the centerline and another allows the lumen portion to rotate independent of the threaded portion.

摘要： A shunt includes a housing having an inlet, an outlet and a flow control mechanism disposed within the housing. A ventricular catheter is connected to the inlet of the housing. The catheter has a longitudinal length, a proximal end, a distal end, and an inner lumen extending therethrough. The inner lumen of the catheter includes at least two lumens at the distal end and has only one lumen at the proximal end. The catheter has one slit and aperture corresponding to each of the at least two lumens located at the distal end of the catheter.

摘要： A system for reaming a cavity in bone for implantation of a prosthetic component, such as an oblong acetabular cup having an outer surface formed by adjacent hemispheres. In one embodiment, the reaming system is useful to form a second cavity in relation to an already formed first cavity. The reaming system includes an instrument with an elongate handle and a drive member coupled to a bearing plate with a locator member removably and replaceably mountable to the bearing plate. The drive member has a distal reamer mating end and a proximal end for coupling with a drill mechanism. The distal reamer mating end is axially movable toward and away from the bearing plate to ream the cavity corresponding to the secondary hemisphere of the acetabular cup to be implanted. In another embodiment, the reaming system includes a plurality of reamers each having different outer dimensions and being matable to the drive member. In a further embodiment, the system includes a plurality of locator members for positioning a respective one of the reamers to form the second cavity at a desired location.
摘要翻译： 一种用于铰接骨中腔的植入物的系统，用于植入假体组件，例如具有由相邻半球形成的外表面的长方形髋臼杯。 在一个实施例中，铰孔系统可用于相对于已经形成的第一腔形成第二腔。 扩孔系统包括具有细长手柄的仪器和联接到支承板的驱动构件，其具有可移除地且可替换地安装到支承板的定位构件。 驱动构件具有远端扩孔器配合端和用于与钻机构联接的近端。 远端扩孔器配合端可以朝向和远离支承板轴向移动，以对应于待植入的髋臼杯的次半球对应的腔。 在另一个实施例中，铰孔系统包括多个铰刀，每个铰刀具有不同的外部尺寸并且可与驱动构件配合。 在另一实施例中，系统包括多个定位器构件，用于定位相应的一个铰刀以在期望位置处形成第二腔。
