Claims20
A system for electromagnetically locating an intragastric device in three dimensional space, in real time, the system comprising:
- a) an electromagnetic field generator configured to generate an electromagnetic field;
- b) a removably attachable inductive reference sensor adapted to be removably attached to a body positioned within the electromagnetic field, whereby a reference sensor signal is generated and the reference sensor signal carries reference sensor position information associated with a position of the reference sensor within the electromagnetic field at an instance in time;
- c) a swallowable target sensor adapted to be positioned within the electromagnetic field, whereby a target sensor signal is generated and the target sensor signal carries target sensor position information associated with a position of the target sensor within the electromagnetic field at the instance in time;
- d) a processor adapted to be in electronic communication with the reference sensor and the target sensor, so as to receive the reference sensor signal and the target sensor signal;
- wherein
- i) the processor processes the reference sensor signal so as to create one or more reference indicia associated with the position of the reference sensor at the instance in time;
- and
- ii) the processor processes the target sensor signal so as to create one or more target indicia associated with the position of the target sensor at the instance in time;
- and
- e) a display adapted to be in electronic communication with the processor and configured to display the one or more reference indicia and the one or more target indicia.

A method for electromagnetically locating an intragastric device inside the body of a patient, the method comprising:
- a) placing a reference sensor on a fixed location on a surface of a patient's body, wherein the reference sensor is configured to:
- i) sense an electromagnetic field directed at the body of a patient, and
- ii) produce a reference sensor signal in response to the sensed electromagnetic field, wherein
- ii) the reference sensor signal is associated with the reference sensor location;
- c) positioning a target sensor on the patient's body, wherein the target sensor:
- i) senses the electromagnetic field, and
- ii) produces a target sensor signal in response to the sensed electromagnetic field, wherein
- iii) the target sensor signal is associated with a plurality of target sensor locations along the path;
- d) creating one or more indicia by processing the signal associated with the locations of the reference and target sensors with a processor;
- e) introducing an intragastric device into the body of the patient, via swallowing, wherein the target sensor is releasably coupled with the intragastric device;
- f) producing a target sensor signal associated with a plurality of intragastric device locations within the patient's body;
- g) confirming a location of the intragastric device inside the patient's body based on the signal associated with the plurality of intragastric device locations within the patient's body;
- and
- h) displaying, on a display, the one or more indicia and an icon indicative of a current location of the intragastric device.
