Patent ID: 8798747

Claim:
A system adapted to be coupled to a body having external appendages including a finger, a toe, an ear, an arm, and a wrist, the system comprising: a non-invasive hemodynamic sensing device including at least a portion configured to be attached to one of the external appendages, the non-invasive hemodynamic sensing device configured to sense a hemodynamic signal indicative of at least a heart rate, produce hemodynamic data associated with the hemodynamic signal, and transmit the hemodynamic data; and an implantable medical device configured to be communicatively coupled to the non-invasive hemodynamic sensing device via a wireless communication link to receive the hemodynamic data, the implantable medical device including: a neural stimulation circuit configured to deliver neural stimulation pulses; and a neural stimulation controller configured to control the delivery of the neural stimulation pulses using one or more neural stimulation parameters tier treating a cardiovascular disorder, the neural stimulation controller including a stimulation parameter adjustment module configured to adjust the one or more neural stimulation parameters using one or more cardiac performance parameters, the stimulation parameter adjustment module configured to compare a heart rate parameter representative of the heart rate to a predetermined threshold heart rate and adjust the delivery of the neural stimulation pulses using an outcome of the comparison, wherein one of the non-invasive hemodynamic sensing device and the implantable medical device includes a parameter generator configured to produce the one or more cardiac performance parameters including the heart rate parameter using the hemodynamic data.
