Certain aspects relate to systems and techniques for luminal network navigation. Some aspects relate to incorporating respiratory frequency and/or magnitude into a navigation system to implement patient safety measures. Some aspects relate to identifying, and compensating for, motion caused by patient respiration in order to provide a more accurate identification of the position of an instrument within a luminal network.

Disclosed herein are systems and techniques for compensating for insertion of an instrument into a working channel of another instrument in a surgical system. According to one embodiment, a method of compensation includes: detecting insertion of an insertable instrument into a working channel of a flexible instrument; detecting, based on a data signal from at least one sensor, a position change of a distal portion of the flexible instrument from an initial position: generating a control signal based on the detected position change; and adjusting a tensioning of a pull wire based on the control signal to return the distal portion to the initial position.

In general, devices, systems, and methods for multi-source imaging are provided.

A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

A surgical instrument assembly is provided. In some embodiments, an example surgical instrument assembly includes a surgical instrument configured to pass through a guide tube having a proximal end and a distal end. The surgical instrument can include one or more arms configured to extend from the intermediate position, each arm having one or more joints positioned along the arm and an end effector attached at the distal end of each arm. The surgical instrument assembly can include a control assembly positioned at the proximal end and configured to control the movement of the joints and the end effectors.

Some embodiments relate to a method of reducing excess mucosa production and/or secretion in the respiratory tract, comprising: introducing into a respiratory tract lumen a device configured for damaging nerve tissue or blocking neural conduction in the surroundings of said lumen, the device comprising a plurality of energy emitters; positioning the energy emitters of the device inside the lumen at a distance from walls of the lumen; and activating the energy emitters to emit energy suitable to damage the nerve tissue enough to suppress parasympathetic nerve activity which causes excess mucosa production and/or secretion.

An endoscope (1) having a suction channel and a suction connector in communication with said suction channel, and a working channel through which a liquid may pass. A valve for diverting the suction through the sampling device through a sample container is provided. The endoscope (1) further includes an actuator (7) for propelling the liquid through said working channel.

The present disclosure describes surgical dilators including a multi-faceted shaped tip and methods of use associated therewith.

Apparatuses, systems and methods are provided for treating pulmonary tissues via delivery of energy, generally characterized by high voltage pulses, to target tissue using a pulmonary tissue modification system (e.g., an energy delivery catheter system). Example pulmonary tissues include, without limitation, the epithelium (the goblet cells, ciliated pseudostratified columnar epithelial cells, and basal cells), lamina propria, submucosa, submucosal glands, basement membrane, smooth muscle, cartilage, nerves, pathogens resident near or within the tissue, or a combination of any of these. The system may be used to treat a variety of pulmonary diseases or disorders such as or associated with COPD (e.g., chronic bronchitis, emphysema), asthma, interstitial pulmonary fibrosis, cystic fibrosis, bronchiectasis, primary ciliary dyskinesia (PCD), acute bronchitis and/or other pulmonary diseases or disorders.

A medical device system for the delivery of energy to a region of a patient's anatomy is provided. An introducer tube defines a lumen therein and bears a first electrode. A second electrode is movable within the lumen between a retracted position and an extended position. In the retracted position, the second electrode is substantially disposed within the lumen. In the extended position, the second electrode extends at least partially beyond the distal end of the introducer tube. In one form, the introducer tube is configured to substantially hold the second electrode within the lumen in a predetermined orientation in the extended position, and the introducer tube prevents the second electrode from substantially rotating within the lumen of the introducer tube during movement into the extended position. In one form, the introducer tube is more flexible in a first plane than in a second plane.
