An intragastric device comprising: an inflation magnet provided within a capsule and configured to move towards a first end of a capsule during activation of the intragastric device by applying a magnetic field externally to a user after swallowing the intragastric device; a first chamber and a second chamber physically separated by a partition having a through hole; a separator connected to the inflation magnet and sealing the through hole before activation of the intragastric device, wherein activation of the intragastric device moves the separator to unseal the through hole to allow a chemical reaction between a first chemical stored in the first chamber and a second chemical stored in the second chamber; a balloon secured to the capsule and collapsed against the capsule before activation of the intragastric device; and an expandable volume configured to expand when the balloon is inflated by a gaseous product of the chemical reaction.

Intragastric device for weight management

A method of achieving instrument independent measurements for quantitative analysis of fiber-optic Raman spectroscope system, the system comprising a laser source, a spectroscope and a fiber optic probe to transmit light from the laser source to a target and return scattered light to the spectroscope, the method comprising transmitting light from the laser source to a standard target having a known spectrum, recording a calibration spectrum of the scattered light from the standard target, comparing the known spectrum and the calibration system and generating a probe and/or probe-system transfer function, and storing the transfer function. Further provided is a method of performing real-time diagnostic Raman spectroscopy optionally in combination with the other disclosed methods.
