Methods and apparatus for treating anaphylaxis using electrical modulation
First Claim
1. A method of treating anaphylaxis, anaphylactic shock, bronchial constriction and/or asthma in a patient comprising applying at least one electrical impulse having a frequency between about 1 Hz and 3000 Hz to at least one selected nerve in a region of a parasympathetic nervous system of the patient, the electrical impulse being sufficient to increase a blood pressure and to relax bronchial smooth muscle and reduce a magnitude of constriction of the bronchial smooth muscle of the patient.

Abstract
Methods and devices for treating anaphylaxis, anaphylactic shock, bronchial constriction, and/or asthma include providing an electrical impulse to a selected region of the vagus nerve of a patient suffering from anaphylaxis to block and/or modulate nerve signals that would regulate the function of, for example, myocardial tissue, vasodilation/constriction and/or pulmonary tissue.

12. A device for the treatment of anaphylaxis, anaphylactic shock, bronchial constriction and/or asthma in a patient comprising:
-
an electrical impulse generator; a power source coupled to the electrical impulse generator; a control unit in communication with the electrical impulse generator and coupled to the power source; one or more electrodes coupled to the impulse pulse generator; and wherein the control unit is operable to modulate the electrical impulse generator for generation of a signal sufficient to elevate a blood pressure and relax bronchial smooth muscle and reduce a magnitude of constriction of the bronchial smooth muscle of the patient when the signal is applied via the one or more electrodes to a selected nerve in a region of the parasympathetic nervous system. - View Dependent Claims (13, 14, 15, 16, 17, 18)

- 19. A method of treating anaphylaxis, anaphylactic shock, bronchial constriction, and/or asthma in a patient, comprising applying at least one electrical impulse to one or more selected nerve(s) in one or more regions of the parasympathetic nervous system of the patient to increase a blood pressure and relax bronchial smooth muscle and reduce a magnitude of constriction of the bronchial smooth muscle of the patient.
