摘要:
It is an object of the present invention to provide a device and method for controlled positioning and/or releasing an object in a body lumen.The device of the invention comprises a liquid filled tube detachably connected to an injecting apparatus at its proximal end and to a holding and releasing unit having a bore configured to hold and release the object, at its distal end. The holding and releasing unit is connected to the tube such that liquid can pass from the tube into the holding and releasing unit bore.The distal end of the tube is capable of being inserted and maneuvered through a body lumen.The object is retained in the device during its manipulation through the body lumen due to frictional force exerted by the holding and releasing unit on the object. The object is released by activating the injecting apparatus to achieve an hydraulic pressure in the holding and releasing unit bore which is higher than the frictional force.
摘要:
The present invention relates to a method for activating an image collecting process, comprising the step of releasing the power source of a component essential to the image collecting process from an inhibition imposed by an external magnet. In an embodiment of the invention the image collecting process is designed to image the insides of a body lumen. The present invention further relates to a packaging suitable for storing therein an imaging system, said package comprising a magnet. The imaging system comprises components essential to an image collecting process, said components operable in accordance with the invention.
摘要:
A system and method for measuring and analyzing motility within a body lumen such as the gastrointestinal (GI) tract, where an in vivo imaging device such as a capsule captures images and transmits the images to a processor, which calculates the motility of the device based on comparison of the images. Preferably, the processor compares the intensity of pairs of images or of elements of pairs of images, generates a variance for the compared images, and calculates the motility of the imaging device from the variances. The motility data may be presented to a user in various manners; for example, a plot of motility over time may be generated, or indications of low motility may be presented to the user of the system.
摘要:
A device, method and system for sensing the temperature or temperature change of an environment. A typically in-vivo device includes an image sensor. The device may sense the dark current noise of the image sensor, and calculate the temperature or a temperature change of the image sensor.
摘要:
A system and method for maneuvering a device in vivo, wherein a tube has a longitudinal axis, a distal end and a proximal end, and an in vivo sensing device is changeably connected to the distal end of the tube. Typically, the sensing device may be moved from one position where it is, for example, within the axial profile of the tube or along the longitudinal axis of the tube, to a second position, where it is not.
摘要:
The present invention provides an optical system for illuminating and viewing a target in which an illumination element and a receiving means are disposed behind a single optical window, and which obtains data essentially free of backscatter and stray light. The optical window of the optical system is configured such that it defines a shape having at least one focal curve, i.e., an ellipsoid shaped dome. The illumination element and the receiving means are geometrically positioned on the focal curve plane or in proximity of the focal curve plane, such that, when illuminating, rays from the illumination elements, that are internally reflected from the optical window, will not be incident on the receiving means.
