First Claim
Patent Images
1. A method of treating hypotension comprising applying at least one electrical impulse to at least one nerve in a selected region of a parasympathetic nervous system of a mammal in need of relief from hypotension, the electrical impulse being sufficient to stimulate the nerve in the selected region of the parasympathetic nervous system and increase blood pressure in the mammal.

8. A device for the treatment of hypotension 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; at least one electrode coupled to the electrical impulse generator; and at least one electrode lead coupled to the electrode for attachment to one or more nerve(s) in one or more selected regions of a parasympathetic nervous system of a mammal; wherein the control unit modulates the electrical impulse generator for generation of a signal suitable for stimulating the parasympathetic nervous system and increasing blood pressure in the mammal when the signal is applied via the electrode lead to the one or more selected regions of the parasympathetic nervous system. - View Dependent Claims (9, 10, 11, 12)

- 13. A method of treating hypotension associated with shock comprising applying at least one electrical impulse to one or more nerve(s) in one or more selected regions of a parasympathetic nervous system of a patient, the electrical impulse being sufficient to stimulate the parasympathetic nervous system such that blood pressure is increased in the patient.
