A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.

Provided is a monitor for monitoring the condition of the interior of a living organism from the surface of the living organism. The monitor is provided with: a probe which includes an observation window and is attached to the organism surface; a unit which irradiates, with a laser, at least a portion of an observation region; a unit which detects scattered light resulting from the laser irradiation; a Doppler analysis unit and a SORS analysis unit which narrow down the observation spots to a first observation spot; and a CARS analysis unit which obtains the optical spectrum for at least one component, and outputs first information indicating the condition of the organism interior on the basis of the intensity of the spectrum.

The invention relates to an infusion catheter device. This catheter device 10 has an elongate, substantially tubular shape defining a longitudinal axis, a distal end (D) and a proximal end (P), configured to be introduced into a conduit (50) having an inner wall (54) and an outer wall (56) and comprising at least one partial or total obstruction (60) or occlusion to be treated, said device comprising, at its distal end (D), one or more infusion orifices (16, 18, 20, 22) for an infusion liquid (LI), and, upstream from the one or more infusion orifices, at the proximal side (P) of the infusion catheter (10), at least one obturating element (70) for temporary obturating, configured to treat said obstruction (60) or occlusion and to perform the infusion of the infusion liquid (LI) downstream from the obturating element (70) and in the obturating position. This device is suitable in particular for cardiac surgery and interventional cardiology.

Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO.sub.2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.

Offset illumination using multiple emitters in a fluorescence imaging system is described. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The emitter comprises a first emitter and a second emitter for emitting different wavelengths of electromagnetic radiation. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of a hyperspectral emission, a fluorescence emission, and/or a laser mapping pattern.

The present invention relates to an electrode, which is an in vivo insertable electrode, including a substrate, an electrically conductive layer formed on the substrate, a platinum black layer formed on the electrically conductive layer, a self-assembled monolayer (SAM) formed on the platinum black layer, and a lubricant layer formed on the SAM, a method of manufacturing the electrode, and a medical device including the electrode. The in vivo insertable electrode according to the present invention provides excellent electrical properties such as low impedance. Further, it shows that friction with tissue occurring when the electrode is inserted is reduced, and trauma during insertion and an immune rejection response after insertion is suppressed. Further, in the long term, it is possible to detect signals with high sensitivity throughout the entire period by preventing bioadhesion of in vivo cells, such as immune cells, and other proteins.

A system for monitoring gas composition in a surgical cavity during an endoscopic surgical procedure includes an gas recirculation system including a main gas flow circuit for fluid communication with a surgical cavity. The system includes a sensor for monitoring a gas species in a gas flow from a surgical cavity of a patient. The sensor is positioned in a channel branching off from the main gas flow circuit coming from the surgical cavity.

Embodiments related to medical imaging devices including rigid imaging tips and their methods of use for identifying abnormal tissue within a surgical bed are disclosed.

Brain drainage device having a rod-shaped hollow body with an inner drainage channel for insertion through the cranium into the brain, a first sensor arrangement with at least one sensor for measuring a physical parameter, and a signal interface; wherein the rod-shaped hollow body has a first region A which, in the applied state, is designed to protrude into the ventricle situated in the brain; wherein the rod-shaped hollow body has a second region B, which is arranged proximally from the first region, wherein the second region is designed to lie in the region of the brain mass in the applied state; wherein the first sensor arrangement is arranged in the second region in order to measure a physical parameter of the brain mass; wherein the first sensor arrangement is connected to the signal interface such that measurement data determined by the first sensor arrangement are transmitted to a measuring system that is to be connected.
