Systems and methods for treating dyspnea, including via electrical afferent signal blocking

摘要

Systems and methods for treating a patient with dyspnea are disclosed. A method in accordance with a particular embodiment includes identifying the patient as suffering from dyspnea, and, based at least in part on identifying the patient as suffering from dyspnea, implanting an electrical signal delivery element within the patient in signal communication with an afferent neural pathway of a carotid body chemoreceptor. The method can further include at least reducing dyspneic sensations in the patient by directing an electrical signal from the electrical signal delivery element to the neural pathway to at least partially block afferent signals from the chemoreceptor.

主权项

1. A method for treating a patient comprising directing an electrical signal from an electrical signal delivery device to a carotid body in a human patient to block afferent signals from the carotid body,
further comprising positioning the electrical signal delivery device with respect to the carotid body such that blocking the afferent signals from the carotid body with the electrical signal does not interfere with afferent signals transmitted by baroreceptor neurons in the patient, wherein the blocking of the afferent signals achieves a therapeutic effect by disabling a function of the carotid body in sensing hypoxia or hypercapnia.
