Methods to Treat Hyperhidrosis Using Electrical Stimulation

The invention disclosed herein proposes the use of electrical stimulation to treat idiopathic hyperhidrosis by decreasing the activity of eccrine sweat glands. Other types of sweat glands may also be targeted. The invention involves the use of an implantable pulse generator (IPG). The target tissue would be implanted with a lead that transmits the electrical signal from the generator to the electrode.

The invention involves embodiments as follows, each of which propose stimulation esing different methods:

• The invention may require stimulating areas of the central nervous system that control emotional sweating. Such stimulation may reduce or eliminate the central nervous system's exaggerated response to normal emotional stress. The stimulation may alter, block, or otherwise reduce the exaggerated response signals. Since the cerebral cortex plays a large role in emotional sweating response, cortical stimulation may alleviate the symptoms of hyperhidrosis. More specifically, the motor cortex may be targeted.

• The vagus nerve may be targeted for electrical stimulation because of its key role in the autonomic nervous system. The signal pathway to activate sweat glands involves carrying a sympathetic signal through autonomic neurons. Stimulation or inhibition of these neurons may disrupt efferent activation of sweat glands and alleviate symptoms.

• A high frequ...
