Abstract
To develop more efficient leads for peripheral nerve stimulation, we have constructed self-sizing spiral cuff electrodes. By snugly fitting around the nerve, these electrodes demonstrate improved stimulation performance. A potential drawback of this design is that sufficiently high pressure applied by the lead to the nerve might lead to nerve damage. To evaluate this potential problem, we optimized the lead design and manufactured a declination of prototypes which were then evaluated using a custom-designed device to measure the pressure induced by a circumferential lead. This device uses dummy nerves ranging from 2 to 3 mm and allows for simulation of post-surgical inflammatory edema and nerve swelling.
