Abstract
Various aspects of the present subject matter provide an implantable medical device. In various embodiments, the device comprises a baroreflex stimulator and a controller. The baroreflex stimulator is adapted to generate a stimulation signal to stimulate a baroreflex. The controller is adapted to communicate with the baroreflex stimulator and implement a baroreflex stimulation protocol to vary an intensity of the baroreflex stimulation provided by the stimulation signal to abate baroreflex adaptation. According to various embodiments, the controller is adapted to implement the baroreflex stimulation protocol to periodically modulate the baroreflex stimulation to produce an effect that mimics an effect of pulsatile pressure. Other aspects are provided herein.
Claims47
A medical device, comprising:
- a baroreflex stimulator to generate a stimulation signal, the stimulation signal being adapted to stimulate a baroreflex;
- and
- a controller to communicate with the baroreflex stimulator and implement a baroreflex stimulation protocol to vary an intensity of the baroreflex stimulation provided by the stimulation signal to abate baroreflex adaptation.
An implantable medical system, comprising:
- means for generating a baroreflex stimulation signal to stimulate a baroreflex;
- and
- means for abating baroreflex adaptation, including means for changing at least one parameter of the baroreflex stimulation signal such that the baroreflex stimulation ranges within a range from a first baroreflex stimulation level and a second baroreflex stimulation level.
A method, comprising:
- generating a baroreflex stimulation signal to stimulate a baroreflex;
- and
- abating baroreflex adaptation, including changing at least one parameter of the baroreflex stimulation signal such that the baroreflex stimulation ranges within a range from a first baroreflex stimulation level and a second baroreflex stimulation level.
