Muscle stimulating device and method for diagnosing and treating a breathing disorder
First Claim
1. A muscle stimulator adapted to treat a breathing disorder, said muscle stimulator comprising:
- a plurality of loops of electrical wire;
a power supply that selectively provides electrical power to said plurality of loops to produce a magnetic field;
a control unit that controls application of said electrical power from said power supply to said plurality of loops of electrical wire;
a selectively attachable collar adapted to be worn by a patient such that said plurality of loops are positioned proximate to a neck of such a patient between a chin and a sternum and relative to at least one muscle group associated with a patient'"'"'s upper airway; and
an implantable, leadless, stimulation element adapted to be located within such a patient at a location where applying an electrical stimulation to such a patient serves to stabilize an upper airway of such a patient without assistance of an implanted device that mechanically suspends tissues associated with the upper airway, and wherein said stimulation element is adapted to enhance excitability of a nerve or muscle tissue proximate to said stimulation element responsive to a wireless application of said magnetic field on said stimulation element.

Abstract
A device and method for magnetic stimulation of muscles for the diagnosis and relief of a breathing disorder, such as obstructive sleep apnea is disclosed. Magnetic stimulation is used to stimulate muscles which serve to stabilize the upper airway of an individual whose nocturnal apneic events are related to diminished muscle tone. A sensor monitors a physiologic characteristic of the patient, a coil is energized to stimulate the appropriate muscles associated with the upper airway, a power supply provides power for energizing the coil, and a control system controls the application of power to the coil based on the output of the sensor. Diagnosis of obstructive sleep apnea is accomplished by measuring the subject'"'"'s compliance in the presence and absence of the magnetic stimulation of the upper airway muscles. The smaller the difference between these two compliance levels, the more likely that patient suffers from obstructive sleep apnea.
