A family of endoscopes includes a non-zero degree endoscope and a zero degree endoscope. The zero degree endoscope includes a first image capture unit mounted in a distal portion of the zero degree endoscope with a lengthwise axis of the first image capture unit substantially parallel to a lengthwise axis of that distal portion. The non-zero degree endoscope includes a second image capture unit mounted in a distal portion of the non-zero degree endoscope with a lengthwise axis of the second image capture unit intersecting a lengthwise axis of that distal portion at a non-zero angle. The first and second image capture units have substantially identical non-folded optical paths.

An insertion instrument includes: a holding member at a distal end of an insertion portion; a first hole formed in the holding member; a second hole that is formed in the holding member and that communicates with the first hole; a long member that is mounted to the holding member and that includes a distal end part and a main body portion; a partitioning member configured to narrow a space in which the main body portion is arranged; and a filler filling a gap around the long member.

An endoscope includes: a distal-end constituting portion provided at a distal end of an insertion portion of the endoscope: an observation window having a field of view direction that intersects a longitudinal axis of the insertion portion: a first flat surface on which the observation window is arranged, the first flat surface constituting a part of a surface of the distal-end constituting portion and having a first intersection angle with respect to the longitudinal axis: a second flat surface constituting a part of the surface of the distal-end constituting portion, the second flat surface being provided on a distal end side or a proximal end side with respect to the first flat surface, and having a second intersection angle with respect to the longitudinal axis, the second intersection angle being smaller than the first intersection angle; and a supply unit arranged on the second flat surface.

Provided is a scope that can comprise a tubular casing, a proximal end, a distal end, an internal volume, a longitudinal axis of extension extending from the distal end to the proximal end, a vertical axis extending perpendicularly to the longitudinal axis of extension and one or more apertures along a length L of the longitudinal axis of extension; a handle having a proximal end and a distal end; and image capture devices each located within the internal volume of the tubular casing.

A rigid scope includes: an objective lens composed of, in order from an object side to an image side, a first lens group having a negative power, a second lens group including a lens having a positive power, and a third lens group including two or more lenses; a relay lens arranged on the image side of the objective lens; a first lens frame that fixes in place a front group including at least the first lens group and the second lens group of the objective lens; and a second lens frame that fixes in place a rear group including one or more remaining lenses constituting the objective lens and at least part of the relay lens.

A system, apparatus and methods for providing a scope having an imaging sensor which provides a two thousand pixel by two thousand pixel array of pixels. The imaging sensor allows for an angle of view to be changed within a field of view by selecting a one thousand pixel by one thousand pixel array within the two thousand pixel by two thousand pixel array of pixels containing imaging data that corresponds to a desired angle of view.

Integrated hysteroscopic treatment systems which includes an endoscopic viewing system, a fluid management system, a resecting device and a controller for operating all the systems.

A medical device and method for conducting therapeutic and diagnostic interventions in the subarachnoid space of a patient in a minimally-invasive manner are provided. The medical device may be provided in the form of a microcatheter (10) which may be inserted into the subarachnoid space, and then navigated within the subarachnoid space, such as along the spinal canal toward the cisterna magna at the base of the patient's brain or to or form any other location within the subarachnoid space. The microcatheter (10) may include a guidewire (14), a fiber-optic lighting element, and a fiber-optic probe (22) or other micro-camera (36) that enables the contents of the subarachnoid space within cerebrospinal fluid (CSF), which is typically clear, to be viewed in real-time as the microcatheter (10) is navigated within the subarachnoid space.

A method of manufacturing a laryngoscope may include forming a blade being straight and having a handle side and a non-handle side, the blade including a structure that extends from a proximal end to a distal end, and configured to connect to a handle at the proximal end. A first channel may be formed through the structure. The first channel may be configured to enable optical signals to pass therethrough. The first channel may include (i) a first aperture disposed at the proximal end of the first channel and (ii) a second aperture disposed at the distal end of the first channel. The second aperture may be oriented at an offset angle toward the handle side such that images captured via the second aperture are at the offset angle.

An image capturing module is used in an endoscope. The image capturing module comprises an image capturing portion having opposed surfaces defined by respective photodetection and reverse surfaces. The reverse surface includes external electrodes disposed thereon. A layered optical portion having a front surface to which light is applied and a rear surface that is opposite of the front surface. The layered optical portion having a plurality of optical members layered together. A layered device having a first principal surface with joint electrodes disposed thereon. A second principal surface opposes the first principal surface. The first principal surface is bonded to the reverse surface. The joint electrodes are joined to the external electrodes. The layered device includes a plurality of semiconductor devices layered together in which the first principal surface is larger in area than the photodetection surface and smaller in area than the rear surface.
