Abstract: A surgical instrument includes a sheath and an ablation catheter disposed within the sheath. The sheath is configured to be inserted into a cavity of a patient's head. The ablation catheter extends along a longitudinal axis and includes at least one expandable ablation member configured to selectively radially expand outwardly from a non-expanded state to an expanded state for selectively ablating tissue within the patient's head. The ablation catheter is selectively translatable relative to the sheath between a proximal retracted position and a distal extended position. In the retracted position, the at least one expandable ablation member is housed within the sheath to thereby prevent the at least one expandable ablation member from radially expanding outwardly. In the extended position, the at least one expandable ablation member is exposed from the sheath to thereby permit the at least one expandable ablation member to radially expand outwardly for contacting tissue.

Abstract: An apparatus includes a shaft assembly and an electrode assembly at a distal end of the shaft assembly. The electrode assembly includes a first conductive segment extending along a first angular range at the distal end of the shaft assembly. The first conductive segment is operable to apply RF energy to tissue at a first polarity. The electrode assembly further includes a second conductive segment angularly spaced apart from the first conductive segment. The second conductive segment extends along a second angular range at the distal end of the shaft assembly. The second conductive segment is operable to apply RF energy to tissue at a second polarity such that the first and second conductive segments are operable to apply bipolar RF energy to tissue.

Abstract: A method of treating epistaxis includes inserting a distal end (124) of an endoscope (112) into a nasal cavity of a patient. At least the distal end of the endoscope includes a working channel (126). The method includes advancing a distal end of an RF ablation catheter through the working channel of the endoscope. The method also includes ablating tissue in a posterior nasal region of the nasal cavity using RF energy transmitted by the RF ablation catheter. A system is also disclosed comprising an RF energy source, a steerable endoscope and an RF ablation catheter.

Abstract: An apparatus (100) includes an endoscope (260, 360), a navigation sensor (220), and an interface feature (110, 112, 114). The endoscope includes a body (262, 362), a shaft (264, 364) extending distally from the body, and a window (266, 366) located at a distal portion of the shaft. The navigation sensor is position at the distal portion of the shaft. The interface feature can couple the navigation sensor with an image guidance system. The navigation sensor can cooperate with the image guidance system to provide feedback indicating a position of the navigation sensor in three-dimensional space.

Abstract: An endoscopic camera has two or more cameras positioned at a distal end, positioned to provide partially overlapping fields of view. The cameras communicate captured digital images the length of the flexible endoscope, where they may be saved and processed to provide additional imaging features. With partially overlapping images from two or more cameras, image processing can provide panoramic images, super resolution images, and three-dimensional images. One or more of these image modes may also be enhanced to provide a virtualization window that displays a portion of a larger or higher resolution image. The virtualization window displays the selected area of the image, and may be moved or zoomed around the image to provide a virtual endoscope repositioning experience, where the endoscope remains statically positioned but the virtualization window presents a sense of movement and navigation around the surgical area.

Abstract: A system (11) includes a medical probe (36) for insertion into a cavity of an organ, which includes a position and direction sensor (60) and a camera (45), both operating in a sensor coordinate system (62). The system further includes a processor (44) configured to: receive, from an imaging system (21) operating in an image coordinate system (28), a three-dimensional image of the cavity including open space and tissue; receive, from the medical probe, signals indicating positions and respective directions of the medical probe inside the cavity; receive, from the camera, respective visualized locations inside the cavity; register the image coordinate system with the sensor coordinate system so as to identify one or more voxels in the image at the visualized locations, and when the identified voxels have density values in the received image that do not correspond to the open space, to update the density values of the identified voxels to correspond to the open space.

Abstract: An apparatus includes a body, a shaft assembly, and a shaft actuation assembly. The shaft assembly extends distally from the body and defines a longitudinal axis. A portion of the shaft assembly is configured to be inserted into an anatomical passageway associated with an ear, nose, or throat of a patient. The shaft assembly further defines a working passageway that is dimensioned to receive an instrument. An actuator of the body is operable to drive the instrument longitudinally relative to the shaft assembly. The shaft actuation assembly is operatively coupled with a proximal portion of the shaft assembly. Further, the shaft actuation assembly is translatable in a distal direction to extend the shaft assembly distally along the longitudinal axis and is translatable in a proximal direction to retract the shaft assembly proximally along the longitudinal axis.

Abstract: A set of pre-operative images may be captured of an anatomical structure using an endoscopic camera. Each captured image is associated with a position and orientation of the camera at the moment of capture using image guided surgery (IGS) techniques. This image data and position data may be used to create a navigation map of captured images. During a surgical procedure on the anatomical structure, a real-time endoscopic view may be captured and displayed to a surgeon. The IGS navigation system may determine the position and orientation of the real-time image; and select an appropriate pre-operative image from the navigation map to display to the surgeon in addition to the real-time image.
