A medical navigation system including a controller configured to: generate a three-dimensional (3D) volume based upon acquired image information of a region of interest (ROI), determine a reference path (RP) to an object-of-interest (OOI) situated within the ROI, the RP defining an on-road path (ONP) through at least one natural pathway of an organ subject to cyclical motion and an adjacent off-road path (ORP) through tissue of the organ leading to the OOI, and an exit point situated between the ONP and the ORP, query an SSD within the at least one natural pathway to obtain SSDI, determine a shape and a pose of one or more portions of the SSD in accordance with the SSDI, calculate an error between the RP and the determined shape and pose of the SSD, and/or determine when or where to exit a wall of the natural pathway and begin the ORP based upon the calculated error.

A medical device includes a handle portion downwardly extending from an examination portion. The handle portion has opposing upper and lower open ends and a through cavity extending therebetween. An illumination assembly mounted within the open upper end of cavity includes a housing, at least one battery disposed within the housing, and an LED disposed at the distal end of an arm extending from the housing. The housing is mounted through the open upper end of the through cavity. According to at least one version, the at least one battery can be removed without removing the housing from the handle portion. The extending arm is supported by the examination portion and configured to provide illumination to a medical target. The medical device can include a vaginal speculum, sigmoidoscope, laryngoscope, anoscope, or other hand-held medical device.

A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric, perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

An introducer for tracheal tube intubation has a proximal section connected to a distal section having an angled bougie tip. The introducer is configurable (i) for use as a bougie in which a tracheal tube is railroaded over the introducer's back end and into a trachea and (ii) for use as a stylet in which a tracheal tube is pre-loaded onto the introducer for insertion into a trachea. In certain embodiments, the introducer has one or more flexible or malleable sections that enable the introducer to bend into different configurations. The flexible/malleable sections have directional bending such that the sections bend in roughly the same plane as the angled bougie tip. This enables an operator always to know the orientation of the bougie tip even after it has been inserted into the trachea. The flexible/malleable sections enable the introducer to be configured with a handle or other type of grip.

A system and method for performing a bronchoscopy. The system may include a bronchoscope, a multi-fluid conduit apparatus, and a switching apparatus. The bronchoscope may include an insertion tube having a distal end, a control section, and a working channel. The multi-fluid conduit apparatus may include a first conduit section operably coupled to a vacuum source, a second conduit section operably coupled to an oxygen source, and a third conduit section operably coupled to the working channel, each of the first and second conduit sections being fluidly coupled to the third conduit section. The switching apparatus may include a valve apparatus operably coupled to each of the first and second conduit sections and an actuator apparatus operably coupled to the valve apparatus. The actuator apparatus may alter the valve apparatus between: (1) a suction supply state; and (2) an oxygen supply state.

An endoscope (1) including a handle (2) arranged at a proximal end and an insertion tube (3) extending from said handle (2) towards a distal end, a bending section (7) arranged at the distal end and controllable by and operator via control input means (8) arranged at the handle (2); and at least one insertion tube part with at least one lumen, wherein the bending section (7) is displaceable in said lumen so as to be movable relative to the insertion tube (3) from a retracted position within said lumen to an extended position at least partially outside said lumen.

Described herein is a video laryngoscope apparatus for inspection of an oral cavity region of a patient is disclosed. The video laryngoscope includes an apparatus body, a camera arm unit configured to receive and releasably attach thereto a disposable laryngoscope blade, a light source coupled to the camera arm unit, a communication unit, and a power source.
