Device for determining the abdominal wall dynamic biomechanical behavior, and a method making use of such a device

A system for non-invasively evaluating or monitoring an intra-abdominal pressure and/or a risk of incisional hernia of a subject at a preventive stage and/or a pre-operative stage and/or a post-operative stage, the system comprising a device and a treatment unit connected to the device, said device comprising:

• an adjustable and flexible frame, the frame comprising a central area, a left lateral area and a right lateral area, each area having a contact face adapted to face the skin of a subject and an opposed external face;
• a network of main sensors suitable for measuring local deformations and/or local forces on the surface of the abdomen of the subject, said network of main sensors being assembled to the frame, wherein at least one main sensor is located in each area of the frame;
• connecting means adapted for connecting said network of main sensors to a treatment unit;
• wherein the treatment unit comprises means for recording and analyzing all or part of the measured local deformations and/or local forces on the surface of the subject and correlating the measured local deformations and/or local forces on the surface of the abdomen of the subject with deep muscular wall behaviors,
• the treatment unit further comprising means of determination of a level of risk of rupture in an abdominal wall.
