    摘要: 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.

    摘要: A robotic surgical system includes an instrument driver and an instrument assembly operatively coupled to the instrument driver such that mechanisms of the instrument driver operate or control movement, operation, or both, of components of the instrument assembly. The instrument assembly components include an elongate flexible guide instrument and an image capture device, wherein the image capture device is configured to capture images of a forward-oriented field of view. The system further comprises a controller operatively coupled to the instrument driver and configured to operate the instrument driver mechanisms in a manner so as to control advancement of the instrument assembly toward a target along a trajectory that maintains the target in the forward-oriented field of view of the image capture device.
