System for detecting an intragastric balloon
First Claim
1. An optical system for locating a volume-occupying intragastric device inside the body, the system comprising:
- an optical sensor configured to sense electromagnetic radiation;
a volume-occupying intragastric device, the volume-occupying intragastric device comprising an intragastric balloon having a polymeric wall, a lumen, and a valve system configured for introducing an initial fill fluid into the lumen of the intragastric balloon when the intragastric balloon is in an in vivo gastric environment, the valve system comprising a swallowable catheter configured to releasably couple with the volume-occupying intragastric device; and
a swallowable light-emitting marker configured to produce electromagnetic radiation, in an in vivo gastric environment, indicative of a location of the volume-occupying intragastric device or a component associated therewith.

Abstract
Devices and methods for treating obesity are provided, including intragastric devices and methods of fabricating, deploying, inflating, locating, tracking, monitoring, deflating, and retrieving the same. In one embodiment, a device includes a balloon capsule having a distal end, a catheter having a proximal end and a distal end, a connector, a light sensor, and a balloon valve. At least one optical fiber extends along the length of the interior of the catheter and through the valve such that a distal end of the optical fiber is positioned at a distal end of the balloon capsule when the catheter is placed within the balloon capsule, and such that a proximal end of the optical fiber can be received by the light sensor.

12. A method for optically locating a volume-occupying intragastric device inside a body of a patient, the method comprising:
-
introducing into the body of the patient, via swallowing, a volume-occupying intragastric device, the volume-occupying intragastric device releasably coupled with a catheter; introducing into the body of the patient, via swallowing, a light-emitting marker configured to be sensed by an optical sensor; sensing the light emitted by the light-emitting marker with the optical sensor; and confirming a location of the volume-occupying intragastric device inside the patient based on sensing the light emitted by the light-emitting marker. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
