Device and method for the treatment of breathing disorders and cardiac disorders
The present invention is related to an implantable medical device for treating breathing disorders and cardiac disorders by delivering stimulation energy to the phrenic nerve, hypoglossal nerves and cardiac muscle tissues.
1. An implantable medical device for treating a patient comprising;
a. a stimulator configured to provide electrical stimulation to a first lead system and a second lead system,
b. said first lead system configured to transvenously place a stimulation electrode in a ranine vein near the patient's hypoglossal nerve and including a processor configured to deliver electrical stimulation to the electrode in the ranine vein near the patient's hypoglossal nerve;
c. said second lead system configured to transvenously place a stimulation electrode near the patient's phrenic nerve and wherein the processor is further configured to deliver electrical stimulation to the electrode near the patient's phrenic nerve; and
d. the stimulator being configured to provide the electrical stimulation to the first lead system slightly before applying electrical stimulation to the second lead system.
2. The device of claim 1 , wherein said stimulator is configured to supply sub threshold stimulation periodically to said first lead system to alter hypoglossal tone to a value near the value of tone during the awake state.
3. The device of claim 1 , wherein said stimulator is configured to supply sub threshold stimulation periodically to said first lead system to alter tone where the level of sub threshold stimulation is selected not to arouse the patient.
4. The device of claim 1 , wherein said stimulator is configured to supply sub threshold stimulation periodically to said first lead system to elevate upper airway muscle tone where level of sub threshold stimulation is selected such that the patient is not aware of stimulation while patient is awake.
5. The device of claim 1 , wherein the stimulator is configured to provide the electrical stimulation to the second lead system at a defined interval.
6. An implantable medical device for treating a patient comprising:
a. a stimulator configured to provide electrical stimulation to a lead system that includes a stimulation electrode: and
b. the lead system configured to transvenously place the stimulation electrode in a lingual vein near the patient's hypoglossal nerve and including a processor configured to deliver electrical stimulation to the electrode in the lingual vein near the patient's hypoglossal nerve;
c. wherein the stimulator is configured to stimulate the hypoglossal nerve from the lingual vein.
7. The device of claim 6 , wherein the stimulator is configured to supply sub threshold stimulation periodically to the lead system to alter hypoglossal tone to a value near the value of tone during the awake state.
8. The device of claim 6 , wherein the stimulator is configured to sub threshold stimulation periodically to the lead system to alter tone where the level of sub threshold stimulation is selected not to arouse the patient.
9. The device of claim 6 , wherein said stimulator is configured to supply sub threshold stimulation periodically to the lead system to elevate upper airway muscle tone where level of sub threshold stimulation is selected such that the patient is not aware of stimulation while patient is awake.
10. The device of claim 6 , further comprising a second lead system configured to transvenously place a stimulation electrode near the patient's phrenic nerve and wherein the processor is further configured to deliver electrical stimulation to the electrode near the patient's phrenic nerve; and the stimulator being configured to provide the electrical stimulation to the lead system configured to transvenously place the stimulation electrode in a lingual vein slightly before applying electrical stimulation to the second lead system.
