Problems solved by technology

[0011] Moreover, common intragastric balloons also have the disadvantage of being somewhat brittle, stemming notably from the fact that the pouch containing the inflation gas (or liquid) also forms the outer shell of the balloon
Thus, the bag is directly exposed to external stresses, which increases the risk of perforation especially when the balloon is being handled by medical workers

Embodiment Construction

[0022] The intragastric balloon according to the present invention will now be described with reference to FIGS. 1 to 2 .

[0023] The intragastric balloon 1 according to the invention is designed to be implanted in the stomach of a patient for the treatment of obesity.

[0024] The intragastric balloon 1 is expandable and to this end comprises a casing 2 which is sufficiently flexible to pass from a reduced volume configuration (shown in Figure 2) to an expanded configuration (shown in Figure 1).

[0025] The reduced-volume configuration may for example correspond to a configuration in which the balloon 1 is in a collapsed state occupying a reduced volume, thereby facilitating insertion of the balloon 1 into the esophagus.

[0026] In fact, the implantation of the intragastric balloon 1 according to the invention takes place essentially in a conventional manner known to those skilled in the art, in its folded, compressed or relaxed form, through the oral-oesophageal route. T...

Abstract

The invention relates to an expandable intragastric balloon which is intended to be implanted in the stomach of a patient for the treatment of obesity. The inventive balloon comprises an outer casing (2) which is sufficiently flexible in order to change from a reduced volume configuration to an expanded configuration, thereby imparting the balloon (1) with its functional shape. The balloon is characterised in that it comprises means (3) for forming the outer casing (2), which are structurally integrated into the balloon (1), but which, for the most part, are separate from the outer casing (2). According to the invention, once the balloon (1) has been implanted, the aforementioned forming means (3) can be actuated in order to: (i) exert a sufficient driving pressure on the outer casing (2) such as to force the deployment thereof, and (ii) occupy a sufficient volume inside the outer casing (2) in order to produce the deployment of the outer casing (2) from the reduced volume configuration to the expanded configuration thereof. The invention is suitable for intragastric balloons.

Description

technical field [0001] The present invention relates to the general technical field of devices implantable into the human body and designed to treat obesity, particularly morbid obesity, and most particularly to devices capable of artificially reducing stomach volume for the specific purpose of inducing a feeling of fullness in a patient Implants. [0002] The present invention relates to an inflatable intragastric balloon designed to be implanted in the stomach of a patient for the treatment of obesity and comprising a housing that is sufficiently flexible to change from a reduced volume configuration to an expanded configuration such that The balloon has its functional shape. Background technique [0003] Intragastric balloons used to treat obesity are usually in the form of a flexible bag that forms the outer shell of the balloon and, once the balloon has been implanted in the stomach, is capable of being filled with an inflation fluid, especially air, so that the balloo...
