    • Systems and methods for controllably traversing a tissue wall. In one embodiment, a distal end of a catheter is positioned and/or repositioned utilizing direct visualization out the distal end of the catheter, as facilitated by an imaging element disposed within the distal tip of the catheter. An inflatable balloon may comprise a portion of the distal tip of the catheter for structural and/or visualization media purposes. A tissue traversing element may be forwarded through a working lumen defined by the catheter and controllably pushed through a tissue wall as observed with the imaging element. The tissue traversing element may comprise sensors and the like to facilitate monitoring of changes in pressure, color, oxygen saturation, flow rate, and echo timing, to determine the position of the tissue traversing member relative to the tissue wall.
    • 用于可控地穿过组织壁的系统和方法。 在一个实施例中,通过设置在导管的远端中的成像元件来促进导管的远端,利用从导管的远端直接可视化来定位和/或重新定位导管。 可充气气囊可以包括用于结构和/或可视化媒体目的的导管的远侧末端的一部分。 组织移动元件可以通过由导管限定的工作腔进入,并且如通过成像元件所观察到的,可控地推动通过组织壁。 组织移动元件可以包括传感器等,以便于监测压力,颜色,氧饱和度,流速和回波定时的变化,以确定组织横向构件相对于组织壁的位置。

    • An inflatable retraction apparatus is provided for retracing an organ inside a body to gain access to an adjacent tissue. The apparatus includes an able chamber formed from a single thin envelope, and capable of being collapsed for insertion through an incision and being expanded to a predetermined shape for retracing the organ. An inflation mechanism is adapted to selectively inflate the chamber to the predetermined shape. The inflation mechanism includes at least one inflation tube attached to the inflatable chamber in fluid communication theretween, and an inflatable maintaining lattice operatively enveloping the inflatable chamber and in operative association with the inflation mechanism. The inflatable maintaining lattice defines a plurality of single layered access windows around the inflatable chamber, and is configured and adapted to maintain the inflatable chamber in substantially the predetermined shape after an aperture is pierced in at least one of the plurality of access windows of the inflatable chamber.
    • 提供一种可充气的收缩装置,用于回收身体内的器官,以便进入邻近的组织。 该装置包括由单个薄壳体形成的能力腔室,并且能够被塌缩以插入通过切口并且被扩展到预定形状以用于回退器官。 膨胀机构适于选择性地将腔室充气至预定形状。 膨胀机构包括至少一个连接到可膨胀室的充气管,其中流体连通,并且可膨胀的维持格子可操作地包围可充气室并与膨胀机构有效连接。 可充气维护格架限定围绕可充气室的多个单层进入窗口,并且被配置和适于在可充气室的多个进入窗口中的至少一个穿孔之后将可充气室保持为基本上预定的形状 房间。
