INSTRUMENT PATH GUIDANCE USING VISUALIZATION AND FLUORESCENCE

In a surgical method using a robotic system, a distal end of a robotically controlled surgical instrument is positioned in a patient body cavity. Operation of the instrument is controlled in response to input provided by a surgeon at an input device. An image of the interior of the body cavity is captured for display on a display. A boundary in the body cavity is identified using the image processing software by distinguishing between different colors on the image. In response to identification of the boundary, at least one of the following modes of operation is performed: providing a haptic contract at the surgeon console constraining movement of the surgical instrument to maintain the instrument along the boundary; preventing activation of an electrosurgical function of the instrument except with the instrument is within a defined distance from the boundary; allowing activation of an electrosurgical function of the instrument only when the instrument is positioned along the boundary

Alternative Fluid-Driven Articulation Architecture for Catheters and Other Uses

Devices, systems, and methods for articulating elongate flexible structures such as catheters optionally include an array of fluid-expandable bodies such as balloons. The array can be formed using separate strings of balloons formed along single-lumen balloon tube material. The balloon strings can be twisted together to form a multi-channel bundle, or the balloon strings may be circumferentially separated, each extending axially. Regardless, the balloons along a common lumen may be aligned so as to bend the catheter in a desired lateral direction. The fluid-expandable bodies may include an elastomeric bladder with a fiber braid so that inflation of the bladder shortens the assembly and applies axial tension to articulate the catheter. The elongate flexible structures may be pre-biased so as to form a bend when in a relaxed configuration, with the structures being articulatable from the bend.
