1. A device for detecting placement of an inflatable intragastric balloon within an anatomical constrained space, the device comprising:
a pressure sensor for detecting a balloon pressure within the inflatable intragastric balloon in vivo; and
a computing device configured to:
a) control delivery of an inflation fluid into the inflatable intragastric balloon;
b) receive a balloon pressure value from the pressure sensor during a balloon administration procedure; and
c) compare the received balloon pressure value to a predetermined pressure range during the balloon administration procedure, wherein a received balloon pressure between 17.2 kPa and 60 kPa and a rate of pressure decrease less than 0.2 kPa/s is indicative of placement of the inflatable intragastric balloon in the anatomical constrained space, and wherein a received balloon pressure less than 17.2 kPa in an absence of a rate of change of less than 0.2 kPa/s in 3 seconds is indicative of placement of the inflatable intragastric balloon in an anatomical unconstrained space.
