一种新型的神经袖电极由嵌入生物相容性绝缘自卷曲鞘内的导电段组成。这种螺旋神经套偏向于自缠绕周围神经，并具有“自调节大小”的特性，提供了一种替代目前市售的、手动缠绕神经并缝合的固定大小神经套（“裂柱”套）。介绍了螺旋袖口的设计与制作。作者假设，与传统的袖带不同，螺旋袖带可以安全地植入，当大小与周围神经紧密贴合时。提出了支持这一假设的传统和螺旋袖口的理论压力分析。这些分析的目的是预测不干扰神经内血流的最小CNR（袖带直径/神经直径比）。将舒适的螺旋袖口植入猫周围神经的初步实验结果支持了它们可能是安全的预测。< >
A novel type of nerve cuff electrode consisting of conductive segments embedded within a self-curling sheath of biocompatible insulation has been developed. This spiral nerve cuff is biased to self-wrap around peripheral nerves and possesses a 'self-sizing' property, presenting an alternative to present commercially available, fixed-size nerve cuffs that are manually wrapped around nerves and sutured shut ('split-cylinder' cuffs). Spiral cuff design and manufacture are described. The authors hypothesize that unlike traditional cuffs, the spiral cuff potentially can be implanted safely when sized to fit peripheral nerves snugly. Theoretical pressure analyzes of traditional and spiral cuffs that support this hypothesis are presented. These analyses are designed to predict the minimum CNR (cuff diameter/nerve diameter ratio) at which there is no interference with intraneural blood flow. Results of a preliminary experiment in which snug spiral cuffs were implanted on feline peripheral nerve support the prediction that they may be safe.< >
