Contact Configuration
The specific arrangement and polarity settings of electrode contacts used to create the desired stimulation field geometry.
Full Definition
Contact configuration refers to the programmed arrangement of electrode contacts, including which contacts serve as anodes (positive), cathodes (negative), or remain inactive during neurostimulation. The configuration determines the shape, direction, and intensity of the electric field generated around the electrode. Options include monopolar (single active contact with distant return), bipolar (adjacent contacts of opposite polarity), and complex multipolar arrangements. Different configurations can target specific neural structures while avoiding others, making contact selection crucial for optimizing therapeutic benefits and minimizing side effects. Advanced devices offer numerous configuration options to personalize therapy for individual anatomy and pathology.
Usage
Usage note: Specify polarity arrangements; distinguish from physical electrode design.
