    • A tissue tunneling device having a gripping mechanism for holding onto the body of the catheter. In one variation, the tissue tunneling device includes an elongate tunneler with a collet attached to the proximal end of the tunneler, and an oversleeve for providing compression to the collet to secure a distal or proximal portion of the catheter within the proximal end of the tunneling device. Internal ribs or surface profiles may be provided on an inner surface of the collet to prevent the catheter from moving when the collet is compressed onto the body of the catheter. The oversleeve may be configured such that over-sliding in the proximal direction is prevented. The collet may further be configured to receive the tips of a split-tip dialysis catheter.
    • 一种具有用于保持在导管的主体上的夹持机构的组织穿隧装置。 在一个实施例中,组织穿隧装置包括细长的隧道器,其具有连接到隧道器的近端的夹头,以及用于向夹头提供压缩以将导管的远侧或近端部分固定在隧道近端内的套筒 设备。 可以在夹头的内表面上设置内部肋或表面轮廓,以防止当夹头压缩在导管的主体上时导管移动。 套筒可以被配置成防止在近端方向上的过度滑动。 夹头还可以配置成接收分流式透析导管的尖端。
