Abstract
Disclosed is a balloon of an intragastric device, comprising, in combination: a core of a first material and having an inner surface and an outer surface; and a coating of a second material on at least one of the inner surface of the core and the outer surface of the core. Disclosed is a method, comprising, in combination: creating a core of a balloon by a core in a first material; dipping at least one of an inner surface of the core and an outer surface of the core in a second material, whereby a coating is formed on at least one of the inner surface of the core and the outer surface of the core. The first material may be of a more dimensional consistency than the second material, have a greater elasticity than the second material, or be primarily of polydimethyl-siloxane.
