    • An embolic protection apparatus having a deflector tube and two expanders each having a plurality of circumferentially spaced, longitudinally oriented fingers. The fingers of each expander have radially constrained ends and radially expandable ends aligned opposite the fingers of the other expander. The deflector tube is disposed within one of the expanders that also has a flexible sleeve covering at least the fingers of the expander. The deflector and the expanders are engageable with each other using compound leverage to transform the apparatus between a collapsed configuration and an expanded configuration wherein the fingers of the covered expander are radially splayed to dilate the sleeve. Also disclosed are a catheter having the protection apparatus and a method of using the catheter.
    • 一种具有偏转管和两个膨胀器的栓塞保护装置,每个膨胀器具有多个周向间隔开的纵向定向的指状物。 每个膨胀器的指状物具有径向限定的端部和径向可扩张的端部与另一个膨胀器的指状物对准。 导流管设置在一个膨胀器内,该膨胀器还具有至少覆盖膨胀机的手指的柔性套管。 偏转器和膨胀器可以使用复合杠杆来彼此接合,以在折叠构型和膨胀构型之间转换装置,其中被覆盖的膨胀器的指状物被径向张开以扩张套筒。 还公开了具有保护装置的导管和使用该导管的方法。

    • An umbilical cord clip and applicator is disclosed for clamping a maternal side of an umbilical cord, applying an umbilical cord clip to a fetal side of the umbilical cord and severing the cord intermediate the clamped maternal and fetal sides of the umbilical cord. The applicator includes a first arm having a first clamping surface, a second arm movably affixed to the first arm and having a second clamping surface and structure associated with at least one the first and second arms for mounting an umbilical cord clip thereon. The applicator also includes a recessed severing mechanism operatively associated with the first and second arms and disposed intermediate the first and second clamping surfaces and the mounting structure. The severing mechanism is automatically actuable upon closure of the first and second arms about an umbilical cord to sever the cord at a location between the first and second clamping surfaces and the clip. The umbilical cord clip includes a first leg having a first clamping surface and a second leg movably affixed to the first leg and having a second clamping surface. A lock device is associated with the first and second legs for maintaining the first and second legs in a closed position about the umbilical cord. Attachment structure is also associated with at least one of the first and second legs. The attachment structure is releasably engagable with the mounting structure on the applicator to hold the umbilical cord clip on the applicator.
    • 公开了一种用于夹紧脐带的母体侧的脐带夹和施用器,将脐带夹施加到脐带的胎侧,并切断在脐带的母体和胎侧的中间的绳索。 施加器包括具有第一夹紧表面的第一臂,可移动地固定到第一臂的第二臂,并且具有与至少一个第一和第二臂相关联的第二夹紧表面和结构,用于在其上安装脐带夹。 施加器还包括与第一和第二臂可操作地相关联并设置在第一和第二夹紧表面和安装结构之间的凹入的切割机构。 当第一和第二臂围绕脐带关闭时,切断机构可以自动启动,以在第一和第二夹紧表面和夹子之间的位置切断绳索。 脐带夹包括具有第一夹紧表面的第一腿部和可移动地固定到第一腿部并且具有第二夹紧表面的第二腿部。 锁定装置与第一和第二腿相关联,用于将第一和第二腿保持在围绕脐带的关闭位置。 附接结构还与第一和第二腿中的至少一个相关联。 附接结构可释放地与施加器上的安装结构接合,以将脐带夹固定在施用器上。
