    • A needle or puncture guard that has inherent probe directing features for use in an in-line configured shunt valve is provided. The guard comprises a base member configured for mounting within the domed reservoir of the shunt valve, and a guide wall seated on the base member. The guide wall is defined by a top wall, an inner side wall, and an opposed outer side wall. The inner side wall has an indented section with an aperture extending through the indented section. The inner side wall can be concavely curved, while the indented section has a curvature that directs instruments that are pressed against the guide wall towards the aperture. A method for performing catheter revisions on a shunt system having a guard within the shunt valve is provided as well. Also provided is a method for placement of an intracranial pressure sensor percutaneously into a ventricular catheter for determining intracranial pressure.
    • 提供具有固有探针引导特征的针或穿刺保护装置,用于在线配置的分流阀中。 护罩包括构造成用于安装在分流阀的圆顶形容器内的基座构件和安置在基座构件上的引导壁。 引导壁由顶壁,内侧壁和相对的外侧壁限定。 内侧壁具有凹口部分,其具有延伸穿过凹入部分的孔。 内侧壁可以是凹形弯曲的,而凹进部分具有将朝向孔径压靠在引导壁上的工具引导的曲率。 还提供了在具有分流阀内的防护件的分流系统上执行导管修正的方法。 还提供了用于将颅内压力传感器经皮放置到心室导管中用于确定颅内压的方法。

    • A trocar apparatus and method for introducing a drainage catheter into a drainage area of the body. The trocar includes a hollow cannula and a rod. The rod has a closed distal end and is longer than the cannula so that it can slide into the cannula and, when fully inserted, project a predetermined distance past the distal end of the cannula. The proximal ends of the cannula and the rod have respective supports which will contact one another to limit the forward motion of the rod into the cannula and an interfitting device cooperatively disposed on the supports to permit the user to hold the rod and the cannula in fixed relationship during insertion of the trocar. A catheter holder is placed on the cannula support. The projecting end of the rod is inserted into a drainage opening in the distal tip of the catheter, and a proximal portion of the catheter is held in the catheter holder, so that prior to insertion the catheter is aligned generally along the outside of the cannula. The flexible tip of the rod aligns itself generally along the axis of the catheter, so that during insertion the catheter presents a small cross-section to the tissue through which it is advancing. After the catheter is advanced to its desired position in the body, the rod is withdrawn into the cannula to free the distal tip of the catheter, the proximal portion of the catheter is released from the catheter holder, and then the cannula and the rod are removed from the body leaving the catheter in place.
    • 一种用于将引流导管引入体内排泄区域的套针针装置和方法。 套针包括一个中空插管和一根杆。 杆具有封闭的远端并且比套管长,使得其可以滑入插管中,并且当完全插入时突出超过套管远端的预定距离。 套管和杆的近端具有相应的支撑件,其将彼此接触以限制杆进入套管的向前运动,并且配合装置协作地设置在支撑件上,以允许使用者将杆和套管固定在固定 插入套管针期间的关系。 导管支架放置在套管支架上。 杆的突出端插入到导管的远端中的排水开口中,并且导管的近端部分被保持在导管保持器中,使得在插入之前,导管大致沿套管的外侧排列 。 杆的柔性尖端本身一般沿着导管的轴线对准,使得在插入期间,导管向其前进的组织呈现小的横截面。 在导管前进到其体内所需的位置之后,杆被拉出到插管中以释放导管的远端,导管的近端部分从导管保持器释放,然后套管和杆是 从体内取出导管就位。
