摘要：
An electrode array attached to neural tissue, such as the retina, necessarily has graded pressure exerted on the tissue, with higher pressure near the attachment point. Greater pressure improves contact between the electrodes and neural tissue while too much pressure may damage neural tissue. Hence it is advantageous to obtain equal pressure across the array field. In the present invention a central attachment point in the electrode field applies the most even pressure. Further, multiple and selective attachment points may be additionally provided on an electrode array allowing a surgeon to select the attachment points providing the best electrode tissue contact.
