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。
