    Abstract: An improved self-sealing gasket provides hemostasis while reducing the force required to move a catheter or guidewire positioned within the gasket. Slits formed on one surface of the gasket intersect with a central aperture formed on the opposite face of the gasket. An annular ring formed on the gasket assists in retaining the gasket within a catheter introducer. An annular shelf may be provided distally of the gasket to prevent dislodgement of the gasket if an instrument is inserted into the introducer off axially.

    Abstract translation: 改进的自密封衬垫提供止血，同时减少移动位于垫圈内的导管或导丝所需的力。 在垫圈的一个表面上形成的狭缝与形成在垫片的相对面上的中心孔相交。 形成在垫圈上的环形圈有助于将垫圈保持在导管引导器内。 如果将仪器从轴向插入引导器中，则可以在垫片的远侧设置环形搁架以防止垫圈的移位。

    Abstract: An improved self-lubricating catheter and guide wire introducer (2) is provided with a reservoir (30) containing lubrication fluid located proximally of a sealing gasket (8) in a modified end cap (14). An improved self-sealing gasket provides hemostatis while reducing the force required to move a catheter or guide wire positioned within the gasket.

    Abstract: A surgical instrument assembly has an endoscope with an instrument channel and a sheathed elongate tubular member inserted into the instrument channel. The sheath is provided with a distal end portion having at least one resiliently biased, curved portion tending to direct the tip of the distal end portion in a direction angularly offset from the axis of the body insertion tube at its distal end. The elongate tubular member is itself longitudinally slidably positioned within the sheath. The instrument channel exerts forces sufficient to straighten the curved portions of the sheath when the curved portions are positioned within the body insertion tube, proximal of the tube's distal end. An elongate flexible endoscopic instrument is mounted into the tubular member so that an operative tip is located at a distal end of the tubular member.
