The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.

A power source apparatus and a system incorporating said power source for medical capsules are disclosed. A medical capsule often includes a power source sealed in a housing. Embodiments of the present invention allow the medical capsule to enable/disable electrical power supplied to a sub-system in the capsule device without special tools and/or skills after the medical capsule is manufactured. In one embodiment, the power source apparatus comprises a plunger responsive to a magnetic field, a spring to interact with the plunger, a battery and a control piece. The plunger is moved between first and second positions according to a magnetic field applied externally. Accordingly, the control piece enables or disables the power depending on the plunger positions. In another embodiment, a capsule system uses an electrical interconnect with pressure contacts between the power source and the capsule sub-system connecting the second circuit board to the power-output nodes.

An otoscope provides a disposable speculum sleeve that conducts light to a narrow tip holding an electronic camera. By removing the light source from the tip, the diameter of the tip may be further reduced to allow the space of the ear canal to be shared between the otoscope and a tool such as a curette for removing foreign objects or to permit the tip to navigate around ear obstructions. The sleeve may provide for multidirectional illumination of the ear structure for improved visualization. The tip and sleeve may be flexible for increased patient comfort when using a compact tip design.

An endoscope may include a shaft having a longitudinal axis, a first image sensor facing a distal direction, and a second image sensor facing a lateral direction. The endoscope may further include a tubular member having a lumen, the lumen having a distal-end opening and defining a longitudinal axis through a center of the lumen. The tubular member may be movable between a first configuration and a second configuration. In the first configuration of the tubular member, the longitudinal axis of the lumen may be parallel to the longitudinal axis of the shaft. In the second configuration of the tubular member, the longitudinal axis of the lumen may extend through a lateral opening in a wall of the shaft.

A mounting clamp is disclosed for an illuminated surgical retractor system having a handle that supports an illuminated surgical retractor blade. The mounting clamp is attached to and depends from the handle. The mounting clamp includes a receptacle for receiving a slide bar or other fixed component of an operating room table. The clamp further includes a fastener that is selectively tightened to secure the retractor assembly to the fixed component of the table. The fastener is selectively loosened to disengage the retractor assembly from the fixed component of the table.

An intraoral imaging device comprises an elongated structural element; one or more light sources mounted on the structural element and configured to illuminate a target intraoral structure; one or more sensors mounted on the structural element and configured to detect the light returned from the illuminated target intraoral structure in order to generate an image; and a light absorbing divider dividing each of the light sources from an adjacent sensor and configured to obstruct direct emission of the light from the one or more light sources to the adjacent sensor.

The invention provides an imaging system comprising an optical element for deflecting axially incident light into a series of axially spaced outward radial projections, and further comprising an image collection means for collecting reflected light. The element comprises a plurality of light deflecting surfaces or features which are arranged at axially successive points along the element, each at a different radial location. The light-deflecting surfaces are arranged to deflect light incident upon them from an axial direction in a radial direction, each thereby generating a radial projection of light from the element. A beam or beam bundle projected along the element has successive outer annular layers stripped by the facets and deflected outwards at different axial points along the structure.

A multiple sensor endoscope system and a video processing method, wherein the system includes an endoscope having a plurality of daisy chained image sensors and a central control unit, is described. At least one daisy-chained image sensor includes a sensor array for capturing images and generating video packets from the captured images, a video compression unit configured to compress the video packets, a self-packet buffer configured to store the video packets, a serial-to-parallel de-serializer input unit configured to convert serialized input video packets to parallel data, a chain packet buffer configured to store the video packets received from previous-in-chain image sensors, an arbitration unit configured to interleave the stored video packets, and a serial output unit configured to output serially the interleaved video packets. The central control unit is configured to de-interleave the video packets and regenerate separated images as captured by the plurality of daisy chain image sensors.

A light transmitting probe for use in endodontic procedures comprises a light transmitting core and a metallic sheath surrounding said core. The metallic sheath defines a reflective inner surface. The probe further includes a plurality of apertures formed in the sheath, such that light can exit said probe through the apertures.

Disclosed herein are methods and devices for treating pancreatitis. In the methods described herein, the distal portion of a catheter is routed into the pancreatic duct. The catheter delivers to the pancreatic duct an effective amount of a composition at an effective infusion pressure, wherein the amount and infusion pressure of the composition are effective to decrease the secretion of digestive enzymes from one or more exocrine tissues of the pancreas. The reduction of digestive enzymes may reduce damage to the islet cells typically seen in chronic pancreatitis. Backflow of the composition out of the pancreatic duct is limited, for example, by an occluding system, and aspiration system, or both.
