Introduction.
Electrical stimulation is used in experimental human pain models.
The aim was to develop a model that visualizes the distribution of electrical field in the esophagus close to ring and patch electrodes mounted on an esophageal catheter and to explain the obtained sensory responses.
Methods.
Electrical field distribution in esophageal layers (mucosa, muscle layers, and surrounding tissue) was computed using a finite element model based on a 3D model.
Each layer was assigned different electrical properties.
An electrical field exceeding 20 V/m was considered to activate the esophageal afferents.
Results.
The model output showed homogeneous and symmetrical field surrounding ring electrodes compared to a saddle-shaped field around patch electrodes.
Increasing interelectrode distance enlarged the electrical field in muscle layer.
Conclusion.
Ring electrodes with 10 mm interelectrode distance seem optimal for future catheter designs.
Though the model needs further validation, the results seem useful for electrode designs and understanding of electrical stimulation patterns.
