DEVICES, SYSTEMS, AND METHODS FOR TREATING DISEASE USING ELECTRICAL STIMULATION

Electrical stimulation devices and associated systems and methods are disclosed herein. In some embodiments, the electrical stimulation device comprises a first elongate member having a closed distal end and one or more first conductive elements and a second elongate member having one or more second conductive elements. The second elongate member can be configured to be received within a lumen of the first elongate member such that the first and second conductive elements are aligned and in electrical communication. The device can be configured to be inserted transnasally into a pharynx of a patient and current can be applied from an electric current generator to the second conductive elements, from the second conductive elements to the first conductive elements, and from the first conductive elements to the patient's pharynx. As the first elongate member may be configured to prevent bodily tissues and fluids from contacting the second elongate member, the second elongate member may be reusable while the first elongate member is disposable.
