The BEP™ system: external biomechanical modulation of satiety

An anatomically optimized, adjustable compression system designed to interact with mechanical satiety signals — without entering the body, without pharmacology.

Proprietary biomechanical design — Patent pending
01 — Core principle

Controlled extra-parietal abdominal compression

GASTER control® applies a controlled external pressure to the epigastric region — the area immediately below the xiphoid process, between the costal margins. This zone corresponds to the anatomical projection of the gastric fundus, where mechanoreceptors involved in satiety signaling are concentrated.

The compression is strictly extra-parietal: it acts on the abdominal wall from the outside, without any contact with internal structures. This differentiates GASTER control® fundamentally from intragastric balloons, endoscopic devices, or any form of invasive intervention.

Extra-parietal means the pressure is applied externally to the abdominal wall. No element enters the body. No anatomical modification occurs. The mechanism is exclusively mechanical and fully reversible.

Extra-Parietal Balloon: an anatomically optimized component

At the core of GASTER control® lies the Extra-Parietal Balloon (BEP™) — a triangular or flattened ovoid inflatable structure, anatomically shaped to match the peri-xiphoid region. Its geometry follows the inverted V formed by the costal margins, ensuring precise contact with the epigastric target area.

Pressure distribution and structural reinforcement

The BEP™ is covered by a semi-rigid compressive shield incorporating 5 to 7 segmented reinforcement blades (aluminum or composite). This architecture ensures uniform pressure distribution across the active surface, prevents lateral balloon deformation, and directs the compression force perpendicularly toward the underlying anatomy.

A visual positioning marker guides alignment with the xiphoid process, ensuring reproducible placement across uses and users.

03 — What makes it different

External compression vs. existing approaches

Most existing compression devices act on a broad abdominal zone without precise targeting. The resulting pressure is diffuse, poorly calibrated, and inconsistent between uses. GASTER control® addresses these limitations through anatomical specificity and structural engineering.

Conventional approaches
Broad, untargeted abdominal compression
Variable positioning at each use
Lateral balloon deformation under pressure
No differentiated textile architecture
GASTER control® BEP™
Targeted epigastric compression (peri-xiphoid)
Reproducible positioning via visual marker
Semi-rigid shield prevents deformation
Rigid frontal / elastic lateral textile zones
04 — Textile architecture

Engineered for compression, comfort, and breathability

The belt integrates a differentiated textile architecture — combining rigid and elastic zones to balance mechanical efficiency with wearability.

Frontal zone — rigid

Low-extensibility materials (laminated PVC, reinforced nylon) form a stable backing plane for the compression assembly. This zone contains the compressive shield, the reinforcement blades, and the positioning marker.

Lateral and dorsal zones — elastic

Elastane and mesh textiles allow trunk mobility, respiratory comfort, and adaptation to body movements. This ensures the device can be worn during daily activities — walking, sitting, working — without constraint.

A mechanical pulley tension system enables fine-tuned peripheral rigidity adjustment, ensuring stable compression across varied morphologies and waist sizes from ~75 to 145 cm.

05 — Meal cycle integration

Designed to work with the natural dynamics of eating

GASTER control® is not a static device. Its use follows the temporal structure of meals, with distinct mechanical contributions at each phase:

1
Pre-meal — 15 to 30 minutes before Mechanical preparation of signal conditions. The compression primes the abdominal wall and prepares the perception of gastric volume before food intake begins.
2
During the meal Amplification of distension-related signals as the stomach fills. The external pressure interacts with the expanding gastric wall, supporting earlier recognition of fullness and spontaneous portion reduction.
3
Post-meal — 20 to 40 minutes after Maintenance of perceived satiety, limiting post-prandial snacking and prolonging the sensation of fullness beyond the active eating period.
The device does not create satiety. It modifies the conditions of signal expression, supporting a more conscious and physiologically grounded integration of fullness cues.
