Abstract

Systems and methods identify the physical, mechanical, and functional attributes of multiple electrode arrays. The systems and methods provide a structure adapted for contact with tissue in an interior body region. The structure possesses a physical property affecting tissue contact. The systems and methods include an identification code that uniquely identifies the physical property of the structure, such as size of the structure, or shape of the structure, or symmetry or lack of symmetry of the structure, or a stiffness value of the structure, or combinations thereof. The systems and methods also include an identification element attached in association with the structure to retain the identification code. The identification element is adapted to provide an output representative of the identification code. The structure also carries at least one electrode. The electrode possesses-a physical property, or both. The identification code uniquely identifies both the physical property of the structure and the physical or functional property of the electrode. The identification element retains one or more of these physical or functional properties for output and consideration prior to use of the structure.
