System and method for neural stimulation
First Claim
1. A method, comprising:
- disposing one or more electrodes at a location for stimulating vagus nerve of a patient;
configuring a stimulation channel of an implantable device to deliver electrical stimulation to the one or more electrodes;
delivering neural stimulation pulses through the stimulation channel, wherein the neural stimulation pulses are delivered as a pulse train having first and second phases of opposite polarities; and
,while monitoring the patient, adjusting the pulse amplitude and/or pulse width of the first phase to achieve a desired therapeutic benefit and adjusting the pulse amplitude and/or pulse width of the second phase to achieve a desired reduction in side effects.

Abstract
Various aspects provide an implantable device. In various embodiments, the device comprises at least one port, where each port is adapted to connect a lead with an electrode to the device. The device further includes a stimulation platform, including a sensing circuit connected to the at least one port to sense an intrinsic cardiac signal and a stimulation circuit connected to the at least one port via a stimulation channel to deliver a stimulation signal through the stimulation channel to the electrode. The stimulation circuit is adapted to deliver stimulation signals through the stimulation channel for both neural stimulation therapy and CRM therapy. The sensing and stimulation circuits are adapted to perform CRM functions. The device further includes a controller connected to the sensing circuit and the stimulation circuit to control the neural stimulation therapy and the CRM therapy. Other aspects and embodiments are provided herein.
