    摘要： The invention provides a surgical clip applier particularly useful in laparoscopic and other least invasive surgical procedures. The clip applier includes a shaft having a distal end and a proximal end, the shaft defining an axial direction. Means are provided in the shaft for advancing a clip to the distal end. Hook means are fixed to the distal end of the shaft, the hook means having a distal portion disposed transverse to the shaft so as to define a surface facing in a proximal direction for engaging a tissue structure. A pair of movable jaws are mounted at the distal end of the shaft and are axially slidable relative to the hook means for closing a clip on a tissue structure engaged by the hook means. The movable jaws will define a U-shaped slot open in a generally distal direction. Means are further provided for advancing the jaws to a position adjacent the distal portion of the hook means, as well as means for closing the jaws. The clip applier is particularly advantageous in providing the capability to engage a tissue structure in the hook means and reposition the tissue structure and/or hold the tissue structure in tension while a surgical clip is applied.

    摘要： Controllable stiffness guidewires and methods of using such guidewires are disclosed. According to aspects illustrated herein, there is provided a controllable stiffness guidewire that includes a substantially flexible core wire having a distal section and a proximal section. A plurality of beads may be slidably disposed between the distal section and the proximal section of the core wire. In an embodiment, the beads may be contiguous with one another. The guidewire may further include an actuator designed to compress the beads against one another along the core wire. By compressing the beads against one another, the stiffness of the core wire, and thus the guidewire, can be variably increased between substantially flexible and substantially rigid.

    摘要： The present disclosure provides methods and systems for endoscopic visualization inside the human body and performing clinical procedures under endoscopic guidance. In one embodiment, an endoscopic cannula of the present disclosure may include an elongated body having a channel along which an endoscope can be advanced. The cannula further includes a tip about a distal end of the elongated body, which can be inflated from a substantially firm collapsed state to an expanded state. The cannula also includes a tube situated within the channel and attached at its distal end to a distal region of the tip to permit forward advancement of the tube along with the tip when the tip is expanded. The tube in combination with the channel form a working conduit for passing surgical instruments beyond the tip.
