Meshes in Surgery – and the Difference of DeltaMesh

Meshes were originally used in hernia surgery, i.e. in the treatment of “hernias” such as inguinal or umbilical hernias. Their purpose is to cover weak areas and stabilize the abdominal wall. Both absorbable and non-absorbable materials are used.

At the level of the diaphragm, however, the situation is fundamentally different: Here, the goal is not simply to close a defect, but to restore the stability of the diaphragm. A stable diaphragm is the preposition for effective reflux control.

Nevertheless, conventional flat meshes from hernia surgery are also applied to the diaphragm, focusing primarily on covering the defect itself as the surgical target. These meshes are placed over large areas—sometimes up to 15 cm—fixed in position, or even wrapped around the esophagus. This inevitably creates contact with sensitive organs such as the stomach, liver, and esophagus, which may lead to complications due to adhesions.

However, simply covering the opening does not restore the functional stability required at the diaphragmatic hiatus—thereby explaining their only moderate success.

DeltaMesh — The Key Difference

The DeltaMesh, developed as part of the l.o.e.h.d.e. procedure, follows a completely different principle:It does not cover a defect, but is integrated into the muscle and stimulates the tissue to stabilize itself.

For this reason, it is fundamentally different in design:

• small (approx. 2–3 cm instead of up to 15 cm)

• no flat coverage, but targeted integration into the muscle

• not visible within the abdominal cavity

• no contact with stomach or intestines

• no fixation with tacks or adhesives required

  
  

The DeltaMesh has a three-dimensional structure, is adapted to the anatomy of the hiatus, and supports the targeted reconnection of the diaphragmatic muscles.It does not act like an applied “patch,” but rather as an internal reinforcement.

Conclusion

A “mesh” is not the same as a “mesh.”DeltaMesh is a three-dimensional implant specifically designed to match the unique anatomy and function of the diaphragm.While conventional meshes merely cover defects, DeltaMesh supports the body’s own muscular closure mechanism.
