The BEP™ module: architecture of an extra-parietal compression system

An anatomically shaped, manually inflated compression module, engineered for reproducible positioning and stable pressure distribution — strictly external, with no energy source and no pharmacological component.

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. Positioning at this anatomical landmark is what makes the applied pressure reproducible from one use to the next.

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 — by manual deflation via the valve, or by removing the belt.
Non-invasive Non-active No pharmacological action Immediately reversible

Extra-Parietal Balloon: an anatomically shaped 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 target area.

Inflation and release

Inflation is manual, by means of an integrated ventral hand pump, with no electrical supply and no external energy source. Release is immediate through the manual valve. Pump capacity is bounded by design: it constitutes a technical safety limit, not a target for use.

Pressure distribution and structural reinforcement

The BEP™ is covered by a semi-rigid compressive shield incorporating segmented reinforcement blades. This architecture ensures uniform pressure distribution across the active surface, prevents lateral balloon deformation, and directs the compression force perpendicularly toward the contact area.

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

03 — Engineering differentiation

Targeted compression vs. conventional support belts

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 engineering limitations through anatomical specificity and structural design.

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 sewn 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 form a stable backing plane for the compression assembly. This zone contains the compressive shield, the reinforcement blades, and the sewn positioning marker.

Lateral and dorsal zones — elastic

Elastane and mesh textiles allow trunk mobility and respiratory comfort, and adapt to body movements. The device is designed to be worn during ordinary daily activities, in accordance with the precautions set out in the instructions for use.

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

05 — Conditions of use

An adjustable device, used within a defined framework

The level of compression is set by the user, progressively, and adapted to individual morphology and comfort. The device is intended for short-term, intermittent use during the day, with regular breaks, and is not worn continuously beyond 30 days.

1
Fitting The belt is positioned over a thin garment, never directly on the skin, with the sewn marker aligned to the xiphoid process. Closure is firm but must allow deep breathing and normal speech.
2
Progressive inflation The module is inflated by successive strokes of the manual pump. Inflation stops at a firm but comfortable level. Maximum pump capacity is a safety limit, never a target.
3
Release and removal Opening the valve releases the pressure immediately. The module is fully deflated before the belt is removed.
Use of the compression function takes place exclusively within the normal conditions of use defined by the instructions for use, reference LLGC20251201 v.1 — contraindications, precautions and operating instructions. The device is supplied on medical prescription.
06 — Platform technology

A component, not only a finished device

The BEP™ module was designed as a self-contained sub-assembly that can be integrated into host garments and orthotic devices manufactured by third parties. The host manufacturer retains its own brand, its own channels, and its responsibilities as legal manufacturer of the finished device.
