    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.

    摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a dissection cradle that is resiliently supported along an axis skewed relative to the axis of the cannula. The dissection cradle, in operation, is extended to cradle the target vessel, and the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate a side branch for exposure to a surgical tool. The retractor includes a hollow support and a spray nozzle disposed in the distal end of the retractor to form an irrigation system and lens washer that can be selectively positioned to direct the spray of irrigation fluid at a remote surgical site or at an endoscopic lens.

    摘要： A sliding gas-tight seal on an access port promotes insufflation of an anatomical space formed in tissue at a surgical site only during insertion of an endoscopic instrument through the access port into the anatomical space, and promotes deflation of the inflated space upon removal of the endoscopic instrument from within the access port. An inflatable balloon disposed about the port near the distal end may be selectively expanded to seal and anchor the access port within an incision through which a surgical procedure with insufflation is to be performed. Multiple resilient seals may be attached to the body of the port, and an auxiliary resilient seal may be inserted within the aperture of a seal attached to the body to accommodate a wide range of endoscopic instruments of various exterior dimensions inserted through the seals.
