Definitions

• Non-invasive stimulation of trigeminal nerve branches was found to be safe as a preventive therapy for migraine and as treatment for other conditions such as seizures and depression. Due to the challenge of transferring current through the hair, stimulation of the occipital nerve (greater, lesser and third occipital branches) is mostly performed with implanted nerve stimulators. In spite of that, the occipital nerve branches may also be stimulated transcutaneously.
• the processing unit comprises a transceiver, functionally associated with the at least one electrode or with the at least one sensor, and configured to control operation of and to receive input from the at least one electrode or the at least one sensor.
• the receiver may be any kind of wired or wireless transceiver.
• Figures 11 A and 11B provide top plan views of the inventive headset of Figures 1A and IB in a rest state, in an open and a folded position, respectively;
• Figures 12A and 12B are a perspective view and a front plan view of an anterior member of the inventive headset of Figures 1A and IB, including an embodiment of a size adjustment mechanism according to the teachings herein;
• Figures 21A, 21B, and 21C provide views of another embodiment of a stretchable member having conductive wiring extending therethrough, which stretchable member is suitable for use in inventive headsets according to the teachings herein, Figure 21 A providing a perspective view, and Figures 21B and 21 C providing side plan views in a rest state and in a stretched state, respectively;
• Figure 26 is an anterior view of an embodiment of the inventi ve headset of Figures 1A and IB positioned on the head of a user and including a nose bridge support member;
• An operation indicator 1056 such as an LED light, may form part of user controls and interface 1048 and may be disposed on an exterior surface of anterior member 1012. Indicator 1056 may indicate to a user when the headset 1010 is turned on and/or when the electrode systems 1030 and/or 1040 are active, thereby helping the user prevent unwanted contact with the electrodes when these are operative.
• the user in an initial step of donning headset 1010, the user holds the headset with fingers 1002, such that anterior member 1012 is in close proximity to a forehead of a head 1000 of the user.
• fingers 1002 hold the headset 1010 at posterior members 1016, typically holding a plastic portion of the posterior members so as to ensure the safety of the user.
• the user may hold posterior members 1016 at dedicated, electrically insulating, grips such as those described in further detail hereinbelow with reference to Figures 18A and 18B.
• Electrode pad 56a may be configured to include a peripheral edge 156 that is thinner than the central area of pad 56a.
• Peripheral edge 156 can be made by various manufacturing process such as ultrasonic welding, RF welding or heat compression. By inserting the thin edge 156 into a corresponding groove 152 in housing 150, electrode pad 56a can be reversibly physically coupled to housing 150 and electrically coupled to conductive layer 154.
• H m i t i being a minimum value of H over this entirety.
• FIG. 10A shows posterior member 1016 as well as closure mechanism 1028 and tapered end 1029 of posterior member 1016.
• the tapered end 1029 and the portion of closure mechanism 1028 connected thereto are pointed downward relative to a horizontal axis of posterior member 1016.
• Such positioning of tapered end 1029 provides a pre-load position for plowing, which ensures that while plowing under the hair layers tapered end 1029 maintains contact with the scalp, thereby ensuring that posterior member 1016 and the posterior electrode systems 1040 and/or any other electrodes that are to be positioned below the hair of the user will be in physical and/or electrical contact with the skin of the scalp, and will not be obstructed by layers of hair.
• posterior member 1016 is tapered, such that the width of the posterior member 1016 at the end which is connected to the stretchable member 1018, indicated by A, is greater than the width of the posterior member 1016 at the open end of headset 1010 adjacent closure mechanism 1028, indicated by A', such that A > A'.
• the user changes the aperture 1248 engaging pin 1246 from a more proximal aperture, such as aperture 1248a to a more distal aperture, such as aperture 1248b, thereby extending the section of stretchable member 1018 contributing to the circumference of the headset, and shortening the excess portion 1244.
• magnets 1299a are rotatable within magnet housing 1299 and are arranged so as to attract one another when disposed at a small distance from one another so as to make it easier for the user to close the headset 1010 while donning the headset, without seeing the closure mechanism 1028, as explained hereinabove with reference to Figures 3A to 3E.
• the magnets are arranged so as to attract one another when they are at a distance not greater than 10mm, not greater than 20mm, or not greater than 30 mm.
• the polar orientation of the magnets may adjust itself to an optimal orientation or alignment between the two magnets at a given alignment of or angle between posterior members 1016.
• the magnets comprise Neodymium magnets.
• the microcontroller 1500 may instruct the stimulation circuit 1504 to provide an output signal having a different pattern for each of a plurality of activated pairs of electrodes.
• the stimulation circuit 1504 may stimulate one pair of electrodes at a pulse frequency of 50Hz and a phase duration of 3C tsec and another pair of electrodes at a pulse frequency of 100Hz and a phase duration of 20( ⁇ sec.
• the microcontroller 1500 may activate only one pair of electrodes, may activate a combination of electrodes, may activate several electrodes simultaneously, sequentially, or alternately.
• patients undergoing treatment using the headset may use the interface of external device 1528 to provide input or information regarding their condition, thereby enabling a clinician to monitor the patient's condition and provide recommendations for a modified treatment program or actively modify the patient's stimulation parameters remotely in real time.
• the patient may also use the external interface to download new treatment programs to the headset.
• the user dons headset 1600 in a similar manner to that described hereinabove with reference to Figures 3A to 3E, such that posterior member 1016 plow through the hair and enable posterior sensors 1602b to directly engage the skin of the scalp, and not to be obstructed by layers of hair located thereunder.
