  • Patent number: 11577074
    Abstract: In one aspect, an apparatus for stimulating and/or monitoring a nerve is described herein. In some embodiments, the apparatus comprises a top substrate layer, a bottom substrate layer in facing opposition to the top substrate layer, and a channel disposed between the top substrate layer and the bottom substrate layer. The apparatus further comprises a plurality of electrodes disposed on one or more interior surfaces of the channel. Additionally, the channel is defined by the top substrate layer, the bottom substrate layer, and a retaining wall extending at least partially between the top substrate layer and the bottom substrate layer. The retaining wall retains the nerve within the channel.

  • Patent number: 11172731
    Abstract: Dual-layer insole apparatuses for diabetic foot lesion prevention and related methods are provided. Some insole apparatuses have a body defining a plurality of cavities configured to be coupled to a fluid source. The fluid source can deliver fluid to vary internal pressures of the cavities. The body further defines an insole-shaped structure.
