Methods and systems for determining and mapping a location of a distal end region of an elongate shaft. An illustrative method may comprise obtaining data from an accelerometer located in the elongate shaft adjacent a distal end thereof, determining a length of the elongate shaft inserted into a body from a reference point, merging the accelerometer data and the length of the elongate shaft to localize the distal end region of the elongate shaft, reconstructing a line of travel of the medical device within the body, and superimposing the reconstructed line of travel over an image of an anatomy of the patient.

In order to improve imaging, in particular for low light intensities, an image recording device, in particular formed as an endoscope, is proposed, which comprises a single photon sensitive detector (SPSD) in addition to an image sensor, which uses photodiodes as light-sensitive cells, in order to respectively detect light from a common object area. With the help of the SPSD, additional image information can be obtained from the object area, to improve the image data recorded with the image sensor or to enhance it with additional image information, in particular with regard to a further spectral range, which is captured with the SPSD.

A medical device comprising a handle, a shaft extending from the handle, and an inflatable module at a distal portion of the shaft, the module including a camera, wherein the shaft includes a body defining a first channel extending between a first end configured to be in fluid communication with a fluid source, and a second end in fluid communication with the module, and wherein inflation of the module alters a viewing angle of the camera relative to an axis of the distal portion of the shaft.

Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.

A multifunctional laryngoscope is provided that includes a handle comprising a proximal end and a distal end and a display screen on the handle. The laryngoscope includes a laryngoscope camera at the distal end of the handle and an introducer comprising an orientation sensor at a distal end of the introducer. The laryngoscope includes a processor programmed to execute instructions for receiving from a steering input a steering command in a first reference frame, and mapping the steering command to a second reference frame oriented to the distal end of the introducer based on an orientation signal from the orientation sensor.

A tethered imaging camera encapsulated in a shell lens element of such camera enables viewing from inside and imaging of a biological organ in/from a variety of directions. A portion of camera's optical system together with light source(s) and optical detector mutually cooperated by housing structure inside the shell are moveable/re-orientable within the shell to vary a desired view of the object space without interruption of imaging process. A tether carries electrical but not optical signals to and from the camera and controllable traction cords to move the camera, and a hand-control unit and/or electronic circuitry configured to operate the camera and power its movements. Method(s) of using optical, optoelectronic, and optoelectromechanical sub-systems of the camera.
