A lung volume reduction system is disclosed comprising an implantable device adapted to be delivered to a lung airway of a patient in a delivery configuration and to change to a deployed configuration to bend the lung airway. The invention also discloses a method of bending a lung airway of a patient comprising inserting a device into the airway in a delivery configuration and bending the device into a deployed configuration, thereby bending the airway.

A system and method for wirelessly transmitting a video image signal from an endoscopic camera to a receiver or control unit for storage and/or display on a video monitor. Use of a frame-specific, variable compression algorithm capable of progressively encoding a data stream provides for a better performing and higher quality wireless endoscopic camera system capable of generating images at varying resolutions. Use of a short-range, high-performance wireless technology, such as Ultrawideband (UWB), improves the performance capabilities of the system, while minimizing power consumption and extending battery life. Implementations of error correcting codes, as well as the use of multiple transmitting and receiving antennas, further improve the fidelity of the wireless communication.

An endoscope apparatus includes: a light source device radiating at least one or more illumination lights having a predetermined wavelength band to a subject; a CCD picking up an image of a return light from the subject based on radiation of the illumination light from the light source device; an image processing section outputting a first image signal of a first wavelength band having a peak wavelength of spectral characteristic, between a wavelength band including a maximum value and a wavelength band at a minimum value with regard to an absorption characteristic of living tissue, after image pickup by the CCD; and an observation monitor performing image display on the basis of the first image signal.

Portable surgical systems, methods, and kits are described. The surgical systems may include a camera configured to capture images, viewing equipment configured to receive and display the captured images, a processor, and a stand. The camera, the viewing equipment, the processor, and the stand are configured to be housed in a case. Surgery may be performed using the surgical system by retrieving surgical components from the case, assembling the retrieved surgical components into a surgical system, positioning a patient within the surgical system for surgery, configuring the surgical system, performing the surgery with the surgical system, reconfiguring the surgical system during the surgery, disassembling the surgical system after the surgery, and placing the components in the case.

An endoscope system includes a video processor device that performs signal processing on an image, and an external device that is removably connected to the video processor device and can record light source correspondence information that corresponds to multiple light sources. The video processor device acquires light source correspondence information from the external device and performs signal processing that corresponds to the light source correspondence information.

An imaging system includes: an imaging device including an image sensor provided with an electronic shutter function, the imaging device being configured to capture a subject; a light source configured to emit illumination light for illuminating the subject; an identification unit configured to identify which one of a first light source and a second light source configured to emit light having a wavelength bandwidth different from a wavelength bandwidth of the first light source is employed as the light source used for observation; an electronic shutter controller configured to control the electronic shutter function of the image sensor based on a control pattern according to the classification of the light source identified by the identification unit; and an electronic shutter control pattern setting unit configured to set a control pattern of the electronic shutter function in accordance with the classification of the light source identified by the identification unit.

A tissue manipulation system comprises a reconfigurable hood structure. The hood structure is asymmetric and has a low profile delivery configuration and an expanded deployed configuration which defines an open area bounded at least in part by the hood structure and by an interface surface extending across the hood structure distal end and configured to engage against a tissue region. The open area is in fluid communication with an environment external to the hood structure. The system also includes a catheter in communication with the open area such that introduction of a fluid through the catheter purges the open area of bodily fluid. The interface surface is slanted relative to the catheter longitudinal axis when the hood structure is fully expanded in the expanded deployed configuration. The system also includes an imaging element positioned on the hood structure such that the open area is visualized through the fluid.

Disclosed is a smart lighting system for applying light to teeth in the context of tooth whitening. This particularly concerns teeth that have been provided with a light-curable whitening varnish. The system comprises a light-generating unit, a light-patterning unit, a mouth imaging unit, a mouth image sensing unit, and an image processing and control unit, and is adapted so as to allow the image processing and control unit to adjust the light-patterning unit on the basis of information obtained from the mouth image sensing unit. By doing so, prior to allowing the light-generating unit to emit light, it can be ensured that light emitted to assist tooth whitening, does not affect soft tissue.

There is provided a processor device for an endoscope capable of acquiring a blood vessel index value of a specific observation distance used for predetermined diagnostic criteria. A distance acquisition unit acquires a non-magnified observation distance at the start of the change of the imaging magnification, and acquires magnified observation distance at the end of the change of the imaging magnification. A distance ratio calculation unit calculates a first distance ratio between the non-magnified observation distance and the magnified observation distance. A blood vessel index value calculation unit calculates a blood vessel index value of the non-magnified observation distance from the image signal acquired at the non-magnified observation distance. An index value correction unit corrects the blood vessel index value of the non-magnified observation distance according to the first distance ratio to acquire a blood vessel index value of the magnified observation distance.

This disclosure relates to representing an interior of a volume, such as but not limited to, a lumen. Examples of lumens may comprise a colon or bronchus. An input port receives the captured image data of the interior of the volume. The processor selects one of the multiple candidates such that the selected one of the multiple candidates corresponds to the captured image data. Each candidate is associated with simulated image data of the interior of the volume. The processor stores an association of the selected candidate with the captured image data to represent the interior of the volume. Aspects of the disclosure include computer implemented methods, computer systems and software.
