Abstract:
An in vivo sensing device and system may contain or be used in conjunction with an image sensor and a body lumen clearing element or agent. A method may enable clearing a body lumen for in vivo sensing while using the device of the invention.
Abstract:
Methods of tagging cancerous tissue for diagnostic applications, mainly for cancer screening purposes, include oral or luminal administrating of a tag molecule into a patient's gastrointestinal lumen either orally or through an enema, and tagging cancerous tissue present within the lumen with the tag molecule. The tag molecule may be a near infrared dye, e.g., IR783 or a derivative thereof, which showed to be of high concentration within cancerous tissue compared to normal tissue. The near infrared IR783 dye is administered, either orally or through an enema, as part of a pharmaceutical composition or formulation either as is or conjugated to a specific polymer. The formulation may comprise an enteric coating in order to keep the formulation intact prior to it reaching the target organ, which is to be tagged by the formulation.
Abstract:
A swallowable in-vivo device comprising a shell formed with at least one inlet extending across a shell wall and configured for allowing ingress of fluid at least into the shell; the shell accommodates therein a lateral flow (LF) arrangement configured for absorbing the fluid; the LF arrangement comprises a test zone configured for coming into contact, in-vivo, with a predetermined N substance present in the fluid or a compound comprising the substance, thereby causing a change in at least one property of the test zone; the shell further accommodates a sensor configured for sensing, in-vivo, the at least one property, at least when changed by interaction with the fluid; the LF arrangement has at least one curved segment, and at least one exposure portion juxtaposed with the inlet, configured for absorbing the fluid passing through the inlet into the shell.
Abstract:
A device for cryotherapy treatment of gastrointestinal lesions includes a cooling member that may be attached to a first tube for pressurizing cryogenic fluid through the tube and into the cooling member through nozzles located at the distal end of the first tube. A second tube may be attached to the cooling member for evacuating the cryogenic fluid from within the cooling member, following the fluid's expansion once it exits the first tube. The cryotherapy device may be attached to an endoscope such that the first tube may be passed through the endoscope's working channel, while the second tube may be passed along the endoscope's circumference. The cryotherapy device may further comprise securing means attached to the first tube, for securing the first tube to the endoscope's working channel, thus preventing free rotation of the cryotherapy device within the endoscope, relative to the rotation of the endoscope. In addition, the securing means assist in maintaining a constant and known location of the nozzles relative to the distal end of the endoscope.
Abstract:
Embodiments of the invention include a method and system for displaying an in vivo imaging procedure. The method includes receiving real-time image data captured by the capsule, and continuously generating an updated summarized color bar, said color bar comprising color strips and time scale marks. The color bar is calculated based on color values of received image data, and is updated continuously as new image data is received. The displayed time period is periodically updated, for example based on predetermined fixed time intervals, based on varying time intervals, or based on an accumulated amount of received image data. Other methods of determining the periodic updates may be used.
Abstract:
In-vivo devices, systems and methods for the detection of blood within in-vivo bodily fluids. The methods include irradiating in-vivo fluids passing through a gap in a housing of an in-vivo device introduced to the GI tract of a subject with a plurality of illumination sources positioned on a first side of a gap; detecting with at least one light detector positioned on the opposite side of the gap and facing the illumination sources, light irradiated by the illumination sources; transmitting a plurality of values representing the light detected over time; converting these values to blood concentration values over time, and comparing the blood concentration values to a predetermined threshold value. Based on the comparison, the method includes determining the type of bleeding profile, such that if a plurality of blood concentration values measured consecutively is above the threshold value, the bleeding profile indicates bleeding.

Abstract:
In-vivo methods and kits for detecting presence of a combination of biomarkers indicating colorectal cancer are described. One of the methods includes inserting into a patient a combination of binding agents comprising one binding agent having high affinity to CEACAM5 and at least one binding agent having high affinity to at least one of two biomarkers selected from Olfactomedin 4- (OLFM4) and S100P. The method further includes inserting into the patient an in-vivo sensing device, detecting an optical change using the in-vivo sensing device, which occurs when at least one of the combination of binding agents binds to at least one of the corresponding combination of biomarkers, and determining, based on the optical change, presence of colorectal cancer in the patient.
