Abstract
Various implantable medical device embodiments stimulate an autonomic neural target from within a pulmonary artery, and comprise at least one electrode, a power supply, a neural stimulator connected to the power supply, and an anchor structure. The neural stimulator is configured to generate a neural stimulation signal for delivery to the neural stimulation target through the at least one electrode. The anchor structure is configured to chronically and securely implant the neural stimulator, the power supply and the at least one electrode within the pulmonary artery. The anchor structure, the neural stimulator, the power supply and the at least one electrode are configured to be implanted through a pulmonary valve into the pulmonary artery. In various embodiments, the neural stimulator is configured to be operational to implement a neural stimulation protocol when chronically implanted within the pulmonary artery without a wired connection through the pulmonary valve.

25. A method, comprising:
-
sensing at least one physiological parameter; and stimulating a neural target using a neural stimulator chronically implanted within a pulmonary artery, including implementing a neural stimulation therapy responsive to a sensed physiological parameter when the neural stimulator is chronically implanted within the pulmonary artery, wherein implementing a neural stimulation therapy includes; sensing at least two physiological parameters indicative of autonomic health which can be used as a control input for delivering neural stimulation, wherein the at least two parameters have different time responses to a change in the autonomic health such that a first physiological parameter provides an indication of autonomic health that is more acute than a second physiological parameter; generating a composite index using the at least two physiological parameters, including weighting each of the at least two physiological parameters based at least in part on each parameter'"'"'s time response; and using the composite index to control delivery of the neural stimulation.
