摘要： An improved catheter having a closed distal end and a valve adjacent the distal end which communicates the lumen of the catheter with the exterior of the catheter to permit the infusion or aspiration of fluids between the catheter and the vessel in which the catheter is positioned. The valve is preferably in a plane which is oriented at an angle to the longitudinal axis of the catheter, and is preferably in an area of reduced wall thickness to facilitate opening and closing.

摘要： The present disclosure relates to a valve or seal of the type adapted to allow the introduction of an instrument or object therethrough. In particular, the valve disclosed herein is adapted to maintain a substantially fluid-tight seal with a surgical instrument and is used during a minimally invasive surgical procedure. The valve disclosed herein incorporates one or more bladder members adapted to retain a fluid therein that are associated by one or more interstitial members.
摘要翻译： 本公开涉及适于允许通过其引入仪器或物体的类型的阀或密封件。 特别地，本文公开的阀适合于保持与外科器械的基本上不透液体的密封并且在微创手术过程中使用。 本文公开的阀结合了一个或多个适于在其中保持流体的气囊构件，其中一个或多个间隙构件相关联。

摘要： A reusable cannula for use in minimally invasive surgical procedures is fabricated from a material such as a thermotropic liquid crystal polymer (LCP), e.g., a polymer synthesized from p-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid monomers. The cannula is electrically non-conductive, radiolucent, and experiences an appearance change in response to sterilization by autoclaving. The cannula is fixedly or removably attached to a cannula housing which may have a valve system and/or desufflation port.
摘要翻译： 用于微创外科手术的可重复使用的套管由诸如热致液晶聚合物（LCP）的材料制成，例如由对羟基苯甲酸和6-羟基-2-萘甲酸单体合成的聚合物。 插管是非导电的，可透射的，并且经由高压灭菌对灭菌的反应的外观变化。 套管固定地或可移除地附接到可具有阀系统和/或脱泡端口的套管壳体。
