Stimulation for acute conditions
First Claim
1. Apparatus for application to a subject, comprising:
- an elongated support element having a length of between about 1.8 cm and about 4 cm, and having a proximal end and a distal end;
one or more electrodes fixed to the support element in a vicinity of the distal end thereof;
a receiver, flxed to the support element in a vicinity of the proximal end thereof; and
a control unit, adapted to be coupled to the receiver, and adapted to;
drive the electrodes to apply an electrical current to tissue of the subject, andconfigure the current to have a pulse frequency of between about 10 Hz and about 50 Hz, an amplitude of between about 0.2 V and about 10 V, a pulse width of between about 50 microseconds and about 5 milliseconds, and, in alternation, on periods of between about 1 second and about 2 minutes, and off periods of between about 1 second and about 2 minutes,wherein the control unit is adapted to be positioned inside an oral cavity of the subject, andcomprising an oral appliance, adapted to be fixed to the control unit, and shaped so as to define a surface that fits closely to a roof of the oral cavity.

Abstract
A method for treating a subject is provided, comprising positioning at least one electrode at least one site of the subject for less than about 3 hours, applying an electrical current to the site of the subject, and configuring the current to increase cerebral blood flow (CBF) of the subject, so as to treat a condition of the subject. The site is selected from the list consisting of: a sphenopalatine ganglion (SPG) of the subject, a greater palatine nerve of the subject, a lesser palatine nerve of the subject, a sphenopalatine nerve of the subject, a communicating branch between a maxillary nerve and an SPG of the subject, an otic ganglion of the subject, an afferent fiber going into the otic ganglion of the subject, an efferent fiber going out of the otic ganglion of the subject, an infraorbital nerve of the subject, a vidian nerve of the subject, a greater superficial petrosal nerve of the subject, and a lesser deep petrosal nerve of the subject.

15. A method comprising:
-
inserting an elongated support element into a body of a subject, the element having a length of between about 1.8 cm and about 4 cm, and having a distal end; applying, from a vicinity of the distal end, an electrical current to tissue of the subject; and configuring the current to have a pulse frequency of between about 10 Hz and about 50 Hz, an amplitude of between about 0.2 V and about 10 V, a pulse width of between about 50 microseconds and about 5 milliseconds, and, in alternation, on periods of between about 1 second and about 2 minutes, and off periods of between about 1 second and about 2 minutes. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
