    • The present invention is directed towards a side port for an introducer sheath which precludes the inadvertent excursion a guide wire (or other article or material) through a side port while advancing through the main lumen of an introducer sheath. To prevent inadvertent excursions of a guide wire, the introducer sheath has one or more non-circular side ports. The non-circular component of the side port has a minimum transverse dimension that is smaller than the diameter of the guide wire to be introduced through the lumen of the introducer sheath. Therefore, the small diameter of the non-circular component of the side port prevents a guide wire from inadvertently entering the side port.
    • 本发明涉及一种用于引导器护套的侧端口,其在通过引导器护套的主腔内前进时排除了通过侧端口的导丝(或其他物品或材料)的无意偏移。 为了防止引导线的意外偏移,引导器护套具有一个或多个非圆形侧端口。 侧端口的非圆形部件的最小横向尺寸小于通过引导器护套的内腔导入的导丝的直径。 因此,侧端口的非圆形部件的小直径防止导丝线不经意地进入侧端口。

    • A self-suturing anchor device includes rotatable ring adapted to automatically deploy sutures to secure a catheter. The rotatable ring is utilized in connection with a ratchet mechanism which allows movement of the rotatable ring in a first direction while preventing movement of the rotatable ring in the opposite direction. The rotatable ring is also utilized in connection with a bearing member to facilitate smooth and efficient rotation of the rotatable ring. An extension saddle is utilized to provide a desired amount of displacement between suture securement points to minimize pivotal movement of the catheter. The rotatable ring is wider than its height to minimize kinking of the catheter tube and to relieve pressure when pressed between the patient and a support surface. In another embodiment, a plurality of scallops or other gripping members are utilized to facilitate easy gripping and rotation of the rotatable ring.
    • 自缝合锚定装置包括适于自动部署缝线以固定导管的可旋转环。 可旋转环与棘轮机构结合使用,该棘轮机构允许可旋转环沿第一方向移动,同时防止可旋转环沿相反方向移动。 旋转环还与轴承构件结合使用,以便于可旋转环的平稳有效的旋转。 延伸鞍座用于在缝合线固定点之间提供期望量的位移以最小化导管的枢转运动。 可旋转环比其高度宽,以最小化导管的扭结,并且当在患者和支撑表面之间被按压时减轻压力。 在另一个实施例中,使用多个扇贝或其它夹持构件来促进可旋转环的容易抓握和旋转。

    • A valve apparatus comprising a tubular body having a lumen therethrough and which is adapted for accessing the cardiovascular or other intravenous system of a patient. The body includes a compression chamber communicating with the lumen and adapted to cooperate with a seal. The compressible seal being configured to selectively seal and unseal the lumen in response to a compressive force acting on the seal. The seal having a longitudinal passageway therethrough that communicates with the lumen and is selectively sealed and unsealed in response to changes in the compressive force generated by a plunger assembly. The plunger assembly is configured to apply a certain amount of compressive force on the seal via the engagement of a rotating member and an engagement member under the influence of a rotating end cap. A selecting mechanism comprising a selecting lever and a selecting assembly is movably coupled to the tubular body and communicates with the plunger assembly. The selecting mechanism is configured to selectively vary the compressive force applied by the plunger assembly on the compressible seal, thereby moving the seal from a selectively adjusted position or inactivated position and a sealed or activated position and maintaining the seal in the sealed or activated position.
