1. An intragastric balloon device, comprising:
- a shaft having a plurality of lumens including at least a first lumen with a first aspiration port and a second lumen with a second aspiration port;
a plurality of balloons including at least a first balloon in fluid communication with the first lumen and a second balloon in fluid communication with the second lumen; and
a sealing device having a body attached to the shaft, a head moveably coupled to the body to move between a closed state and an open state, and at least a first plug projecting from the head, wherein—
the head remains coupled to the body between the closed state and the open state,the first plug is configured to seal the first aspiration port of the first lumen against pressure from within the first lumen when the head is in the closed state and further configured to open the first aspiration port of the first lumen when the head is in the open state, andthe first plug includes a channel in fluid communication with the first lumen, wherein (a) the channel is covered by the body of the sealing device in the closed state, and (b) the channel is exposed from the body of the sealing device in the open state.

Abstract
A sealing device attached to an intragastric balloon device having a head flexibly attached to a body by a pivot portion, where the pivot portion provides the head with a closed state and an open state relative to the body and the intragastric device. The sealing device having one or more plugs configured to seal an aspiration port of a lumen when the head is in a closed state and further configured to release the aspiration port of the lumen when the head is in an open state.

12. An intragastric balloon device, comprising:
-
a shaft having a first lumen with a first aspiration port and a second lumen with a second aspiration port; a first balloon attached to the shaft and in fluid communication with the first lumen; a second balloon attached to the shaft and in fluid communication with the second lumen; and a sealing device comprising— a body attached to the shaft, a head moveably coupled to the body to move between a closed state and an open state, wherein the head moves axially relative to the body between the closed state and the open state, and a first plug projecting from the head, wherein the first plug is configured to be inserted into the first lumen to seal the first aspiration port against pressure from within the first lumen when the head is in the closed state, and wherein the first plug is configured to be at least partially removed from the first lumen to open the first aspiration port when the head is in the open state.
