Implant units, manufactured by Medtronic, Inc., have been implanted in 31 patients for treatment of drop-foot. The principal problem encountered in this series was inflammatory reaction. This was observed in seven patients, and was serious enough in five to require removal of the implant. On the positive side, there have been no failures of the implanted equipment for periods of up to 7.3 years, although there is currently a question on one patient. There has also been no documented damage to the nerve from chronic stimulation. Fine wire elctrodes have been implanted intraneurally in a series of animals and in three patients. Preliminary results look encouraging, and this approach seems to hold considerable promise for a new generation of electrode design.
美敦力公司生产的植入装置已被植入31例足下垂患者体内用于治疗。该系列中遇到的主要问题是炎症反应。在7例患者中观察到了这种情况，其中5例严重到需要取出植入物。从积极的方面来看，尽管目前有一名患者存在问题，但植入设备在长达7.3年的时间里没有出现故障。也没有记录表明慢性刺激对神经造成损伤。细钢丝电极已被植入一系列动物和3例患者的神经内。初步结果令人鼓舞，这种方法似乎对新一代电极设计有很大的前景。
