A video laryngoscope has a handle and a blade. A chemiluminescent light source is disposed inside the handle, along with one or more photovoltaic cells which are optically coupled to convert chemiluminescence emitted by the chemiluminescent light source into electrical power. An image sensor is disposed on the blade or in the handle and is configured to image the glottis of a patient when the distal end of the laryngoscope blade operatively engages the tongue of the patient. The image sensor is powered by the electrical power produced by the one or more photovoltaic cells. A system for recording tracheal intubation procedures performed by a plurality of video laryngoscopes is also disclosed.

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 image sensor system, comprising: an image sensor including an image sensing pixel array; a supporting module; a ground line coupling the image sensor with the supporting module; a power line coupling the image sensor with the supporting module; a data/control line coupling the image sensor with the supporting module; and a clock line coupling the image sensor with the supporting module; wherein the ground line and the power line are based on electrical conduction, and wherein the clock line is based on fiber optics.

A method for a minimally invasive surgical system is disclosed including capturing camera images of a surgical site; generating a graphical user interface (GUI) including a first colored border portion in a first side and a second colored border in a second side opposite the first side; and overlaying the GUI onto the captured camera images of the surgical site for display on a display device of a surgeon console. The GUI provides information to a user regarding the first electrosurgical tool and the second tool in the surgical site that is concurrently displayed by the captured camera images. The first colored border portion in the GUI indicates that the first electrosurgical tool is controlled by a first master grip of the surgeon console and the second colored border portion indicates the tool type of the second tool controlled by a second master grip of the surgeon console.

A catheter, comprising: a flexible tubular member having at least one lumen therethrough and a proximal end and a distal end; a plurality of conductive cables extending through at least one of the at least one lumen; and at least one electrically operated component, attached at the distal end and powered by at least one electrical current driven on at least one of the plurality of conductive cables. Some of the plurality of conductive cables are attached to the distal end such that the flexible tubular member is deformed by exerting at the proximal end a tensile force on one of the some of the plurality of conductive cables and a compressive force on another of the some of the plurality of conductive cables, while the at least one electrical current is driven on the some of the plurality of conductive cables.

The present application discloses a reusable or disposable wireless endoscopic viewing device comprising a wireless transmitter, which can be a microchip transmitter. The reusable wireless endoscopic viewing device also comprises a light source, which can be an L.E.D. light source. The application also discloses a kit having the wireless device. A method for using the reusable wireless endoscopic viewing device is also described and is applicable to any target tissue, bone, joint or target area of the body of a subject.

Various embodiments are directed to battery packs for use with surgical instruments. The battery packs may comprise a plurality of cells and at least a portion of the plurality of cells may not be electrically connected to one another. The battery packs may comprise a switch or other mechanism for interconnecting the plurality of cells and may also comprise, or be used in conjunction with, a discharge switch or plug configured to electrically connect an anode of the battery pack to a cathode of the battery pack, for example, via a resistive element.

A device handle is disclosed for grinding substances inside a body lumen, the device handle comprising: a high-speed drive source configured to rotate a treatment member connected to a distal end of a drive shaft; and a low-speed drive source connected to a revolution shaft, and wherein the revolution shaft is configured to cause the treatment member to move about a central axis of the revolution shaft, and wherein the central axis of a proximal portion of the revolution shaft is different from a central axis of the treatment member.

An apparatus of serializer/deserializer is provided. The apparatus comprises an ISP and capture device at a back end with a disposable image-capture module, a synthetic-image module, and a MIPI serializer at a front end; and, after use, only the disposable image-capture module is discarded, which extends into human body at the front end, but keep the other parts reusable, where cost is thus effectively reduced to solve the shortcoming of high cost of the use of modern disposable endoscope.
