Patent ID: 8046069

Claim:
A system coupled to a body having external appendages, 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 including: a hemodynamic sensor to sense a hemodynamic signal allowing for determination of a pulse pressure; a sensor signal processor to produce hemodynamic data representative of the hemodynamic signal; and a sensor telemetry circuit to transmit the hemodynamic data from the non-invasive hemodynamic sensing device; and an implantable medical device communicatively coupled to the non-invasive hemodynamic sensing device, the implantable medical device including: an implant telemetry circuit to receive the hemodynamic data from the non-invasive hemodynamic sensing device; an electrical stimulation circuit to deliver electrical stimulation; an implant signal processor adapted to process the hemodynamic data, the implant signal processor including a parameter generator adapted to produce one or more cardiac performance parameters using the hemodynamic data, the one or more cardiac performance parameters including at least a pulse pressure parameter representative of the pulse pressure; and a stimulation controller adapted to control the delivery of the electrical stimulation using one or more stimulation parameters, the stimulation controller including a stimulation parameter adjustment module adapted to adjust the one or more stimulation parameters using the one or more cardiac performance parameters.
