A trocar is provided that is adapted to insert a lighting attachment into a body cavity. The trocar connects at its distal end to the lighting attachment such that it can be pushed into the body cavity. An endoscope may then be inserted through the trocar into the body cavity. The lighting attachment is configured to detach from the trocar and attach to the endoscope head to provide additional lighting to the endoscope. The lighting attachment includes foldable lighting panels that expand when in use in order to light a wider field of view. The lighting attachment may be powered by induction coil from the endoscope.

An endoscope includes a detachable wireless imaging device and an insertion tube having a distal end region. The attachment of the detachable wireless imaging device detachably attaches the detachable wireless imaging device to the distal end region of the insertion tube.

An endoscope includes a housing with a distal end insertable into a cavity; an image capture device at the distal end to obtain 3D images, and process them to form a video signal; and a folded substrate folded into a U-shape having first and second legs. The image capture device includes a detector and a lens system with right and left multi-band pass filters having right pass bands that are complements of left pass bands. The lens system receives the 3D images including right and left images. The detector faces the lens system to obtain the right and left images. A processing circuit faces the proximal end behind the detector to process signals from the detector. The folded substrate includes the detector at an outer side of the first leg facing the lens system and the processing circuit at an outer side of the second leg facing the proximal end.

Certain aspects relate to biopsy apparatuses, systems and techniques for biopsy using a biopsy pattern. Some aspects relate to moving a distal portion of a medical instrument to one or more sample locations of the biopsy pattern and guiding the instrument to obtain tissue samples from the sample locations within the biopsy pattern. Some aspects relate to obtaining the biopsy pattern and adjusting the sample locations within the biopsy pattern based on various factors such as anatomical features.

Borescopes and related methods that are configured to preclude or minimize imaging in hazy and/or smoky conditions. In some embodiments, the borescope may comprise a shaft made up, at least in part, of a material that is electrically non-conductive material and/or thermally non-conductive, and a tip positioned at a distal end of the shaft. The tip may comprise at least one light source, such as an LED or array of LEDS, configured to deliver electromagnetic radiation in which no more than about 20% of the total spectral output is in the infrared spectrum. The electromagnetic radiation delivered from the at least one light source may comprise a spectrum having at least one of a local maximum and a global maximum between about 450 and about 495 nm. The at least one light source may be configured to deliver between about 20 and about 75 lumens of visible light.

A tongue maneuvering apparatus has a body, a first attachment site, and a second attachment site. The body includes a bulb, a tongue receiving portion, a tongue aperture, and a slot. The body may be a thin, pliable plastic, such as silicone, so as to create proper suction with the tongue when inserted into the tongue receiving portion. A healthcare provider is able to extend and manipulate a patient's tongue so as to clearly view the mouth and throat without activating the gag reflex and maintaining control of the tongue by the provider.

Provided herein is a handle of a multi-camera endoscope, the handle includes a user interface activating unit which includes one or more external activating/control buttons, and an internal activating element, the handle optionally includes a converter configured to receive one or more parallel signals and transform the one or more parallel signals to one or more corresponding serial signals, wherein the parallel signals are output by one or more cameras of the endoscope. Further provided are endoscopes and medical imaging system which include the handle, as well as methods of use thereof.

An endoscopy system having a low-profile multi-imager endoscope. The system is capable of using computational photography to provide enhanced output images using techniques such as super-resolution, foveation, magnification, and two-dimensional to three-dimensional conversion. The enhanced output images can improve clinical decision making and patient treatment. Signals from multiple imagers may be used to affect/adjust handing characteristics of the endoscope or direct semi-robotic guidance thereof.

A system for delivering an agent including a plurality of particles to a target site. The system incudes a catheter having a first wall defining an inner lumen for delivery of the agent to the target site, and a second wall surrounding the first wall to define an outer lumen therebetween for delivery of a fluid to the target site. The catheter has a distal end terminating with a primary opening of the inner lumen and a secondary opening of the outer lumen. A hub associated with a proximal end of the catheter includes a first inlet for receiving a supply of the agent and a second inlet for receiving a supply of the fluid, wherein the first inlet is in fluid communication with the inner lumen, and the second inlet is in fluid communication with the outer lumen.

A plurality of kinds of illumination light are emitted while being switched according to a specific light emission pattern. A plurality of observation images, which are obtained from image pickup of an object to be observed illuminated with each illumination light, are acquired. Control to display the plurality of observation images on a display unit while switching the plurality of observation images according to a specific display pattern is performed. The specific light emission pattern is fixed and the specific display pattern is changeable.
