Patent ID: 7938775

Claim:
An autonomous in-vivo device comprising: a magnetized reagent to be mixed, within said autonomous in-vivo device, with a sample collected from a body lumen; a detector reagent to be mixed, within said autonomous in-vivo device, with said sample; whereby particles within a first portion of said sample, which contains a substance to be detected by said detector reagent, bind to said magnetized reagent and to said detector reagent, and particles within a second portion of said sample, which does not contain the substance to be detected by said detector reagent, do not bind to said magnetized reagent and to said detector reagent; a magnet to detain said first portion of said sample, said magnet not detaining said second portion of said sample; a sensor to sense a property of the detained sample portion; and a transmitter to transmit data of the sensed property.
