Abstract

An embodiment relates to a method for delivering a unidirectional afferent nerve stimulation treatment. A test neural stimulation is delivered, and a physiologic response to the test neural stimulation is monitored. At least one neural stimulation parameter for the test neural stimulation is adjusted if the test neural stimulation does not elicit a desired physiologic response. If the test neural stimulation does elicit the desired physiologic response, at least one treatment parameter for a unidirectional afferent nerve stimulation is determined using the at least one neural stimulation parameter for the test neural stimulation that provided the desired physiologic response. The unidirectional afferent nerve stimulation is delivered using the at least one treatment parameter.

Description

[0001] claim priority [0002] This application claims priority to US Patent Application Serial No. 11 / 695,189, filed April 2, 2007, which is hereby incorporated by reference. technical field [0003] The present application relates generally to medical devices and, more particularly, to systems, devices and methods for delivering unidirectional neural stimulation. Background technique [0004] Experimental and clinical studies have demonstrated the potential negative effects of sympatho excitation in high-risk patients with ischemic heart disease, as well as the possibility of cardioprotection by programmed vagal activity. Common vagal stimulation of the entire vagus nerve tends to lower heart rate, lessen respiration, and lower blood pressure. [0005] Stimulation of vagal afferents through the central spinal cord pathway increases cardiac vagal modulation, thereby providing the benefits of central cardioinhibition without negatively affecting heart rate, respiration, or ...
