Abstract
Electrical stimulation devices and associated systems and methods are disclosed herein. In some embodiments, the electrical stimulation device comprises an elongated member configured to be orally or nasally inserted into a patient's pharynx. The device may further include a conductive element carried by a distal portion of the elongated member and configured to deliver stimulation energy to nearby tissue. The device can include a cover configured to move relative to the conductive elements to selectively cover or expose the conductive elements.
Claims20
A method for stimulating nerves proximate a pharynx of a human patient, the method comprising:
- positioning a distal portion of a stimulation device at a treatment site within the pharynx, the stimulation device comprising:
- an elongated member having a proximal portion configured to be coupled to an energy source and a distal portion configured to be positioned at the treatment site,
- a conductive element carried by the distal portion of the elongated member and configured to be coupled to the energy source to deliver energy at the treatment site,
- a cover, at least a portion of which is disposed at the distal portion of the elongated member, wherein, during positioning of the distal portion, the cover is in a first position in which the cover is positioned over the conductive element, and
- a stop configured to engage the cover to releasably secure the cover in the first position;
- moving the cover from the first position in which the cover is positioned over the conductive element to a second position in which the conductive element is exposed at the treatment site;
- and
- delivering energy to the treatment site with a stimulus from the energy source via the conductive element.
A method for delivering an electrical stimulus to nerves proximate a body lumen of a human patient, the method comprising:
- inserting a distal portion of a medical device through a nasal cavity of the patient, the medical device comprising:
- a stimulation device comprising an elongated member having a proximal portion, a distal portion, and an electrode carried by the distal portion, wherein the electrode is configured to be coupled to an energy source;
- a cover, at least a portion of which is disposed at the distal portion of the elongated member, wherein the cover is movable between (a) a first position in which the cover is positioned over the electrode, and (b) a second position in which the electrode is exposed;
- and
- a slider coupled to a proximal end portion of the cover, the slider being configured to be manipulated by an operator to adjust a position of the cover relative to the electrode;
- positioning the distal portion of the stimulation device and the cover in the first position at a treatment site;
- manipulating the slider to move the cover from the first position to the second position in which the electrode is exposed;
- and
- delivering energy to the treatment site with a stimulus from the energy source via the electrode.
