    • Embodiments of the present invention provide devices and methods for treating various target sites. For example, one exemplary device includes a tubular structure having proximal and distal ends and at least one layer of braided material configured to facilitate thrombosis. The tubular structure includes an end section at the proximal or distal end having a cross-sectional dimension that is larger than that of an opening of the target site. The device also includes a stiffener wire coupled to the tubular structure, wherein the wire is configured to extend at least partially through the opening and facilitate securing the end section over the opening. The tubular structure and stiffener wire include respective preset, expanded configurations and are configured to be constrained to respective reduced configurations for delivery to the target site and to at least partially return to their respective preset, expanded configurations at the target site when unconstrained.
    • 本发明的实施方案提供了用于处理各种靶位点的装置和方法。 例如,一个示例性装置包括管状结构,其具有近端和远端以及配置成促进血栓形成的至少一层编织材料。 管状结构包括在近端或远端处的端部部分的横截面尺寸大于靶部位开口的截面尺寸。 该装置还包括联接到管状结构的加强筋,其中所述线被构造成至少部分地延伸穿过所述开口并有利于将所述端部部分固定在所述开口上。 管状结构和加强筋包括相应的预设的扩展构型,并且被配置为被限制为相应的减小配置,用于递送到目标位置,并且在不受约束时至少部分地返回到其目标位置处的各自预设的扩展配置。

    • A balloon catheter which has an elongate shaft with an inflatable balloon connected to its distal end and a manifold connected to its proximal end. The manifold may be fixedly or removably attached to the shaft and includes a barrel with a plunger movably disposed inside it. The manifold may be held with one hand and the plunger may be actuated with one finger or thumb on the same hand. The barrel may have an internal volume of less than 5 cc and an internal diameter of less than 0.25 inches. The catheter also has a prep port which may be connected at or near the proximal end of the catheter. The prep port facilitates prepping of the catheter system. A seal (e.g. a releasable cap or a valve) may be connected to the prep port for sealing off the prep port during use. A pressure transducer may be mounted to the catheter (e.g. on the shaft, the manifold, the prep port, or the seal) to permit measurement of the pressure within the inflation lumen and the balloon. The pressure transducer may be operably connected to a pressure display and the display may be connected to the proximal end of the catheter or may be remotely located from the catheter. Data may be transmitted to the remote display by wire or wireless transmission (e.g. infrared, radio frequency, or magnetic transmission). Alternate embodiments and methods of use are also disclosed.
    • 一种气囊导管,其具有连接到其远端的可膨胀气囊的细长轴和连接到其近端的歧管。 歧管可以固定地或可移除地附接到轴上并且包括具有可移动地设置在其内的柱塞的筒。 歧管可以用一只手握住,并且柱塞可以用一只手指或拇指在同一只手上致动。 枪管可具有小于5cc的内部容积和小于0.25英寸的内径。 该导管还具有可在导管的近端处或其附近连接的制备端口。 准备端口有利于导管系统的准备。 可以将密封件(例如可释放盖或阀)连接到准备端口,以在使用期间密封准备端口。 压力换能器可以安装到导管(例如在轴,歧管,制备端口或密封件上),以允许测量充气腔和气囊内的压力。 压力传感器可以可操作地连接到压力显示器,并且显示器可以连接到导管的近端,或者可以远离导管定位。 数据可以通过有线或无线传输(例如红外线,射频或磁性传输)发送到远程显示器。 还公开了替代实施例和使用方法。
