Abstract
A method and device is provided for adding to breathing by stimulating tissue to elicit a diaphragm response during intrinsic breathing.
Claims13
A method of treating a breathing disorder of a patient, comprising:
- sensing a respiratory parameter of the patient;
- comparing the sensed respiratory parameter against a threshold level via the stimulator coupled thereto, wherein the threshold level is above the level of the respiratory parameter when respiration ceases;
- when the respiratory parameter meets the threshold level and is indicative of a breathing disorder, electrically stimulating a phrenic nerve or diaphragm tissue with an electrical stimulation signal via the stimulator to adjust a respiratory parameter of the patient, where the electrical stimulation signal comprises a burst or series of pulses;
- and
- activating at least a portion of the diaphragm via the electrical stimulation signal for a time and at a level effective to further control or manage pulmonary stretch receptor threshold levels to maintain upper airway patency.

A device for treating a breathing disorder of a patient comprising:
- at least one electrode in electrical communication with a diaphragm or phrenic nerve tissue of a patient's body;
- a control unit in electrical communication with the at least one electrode whereby the control unit receives respiration activity sensed by at the least one electrode,
- wherein the control unit is programmed to generate an electrical stimulation signal in response to the sensed respiration, programmed with a threshold level of a respiratory parameter, wherein the threshold level being above the level of the respiration activity when respiration ceases, and programmed to deliver the electrical stimulation signal comprising a burst or series of pulses if the sensed respiration activity meets the threshold level and indicates a breathing disorder to adjust the breathing cycle of said patient, said electrical stimulation signal delivered through the at least one electrode to the diaphragm or phrenic nerve tissue, and
- wherein the electrical stimulation signal is configured to activate at least a portion of the diaphragm and to further control or manage pulmonary stretch receptor threshold levels to maintain upper airway patency.
