Problems solved by technology

For example, studies have shown that electrical stimulation of the carotid sinus nerve can cause a decrease in experimental hypertension, and that direct electrical stimulation of the baroreceptor zone of the carotid sinus itself causes a decrease in reflex in experimental hypertension

Abstract

An embodiment of an implantable system configured to be implanted in a patient includes an accelerometer, a neurostimulator, and a controller. The neural stimulator is configured to deliver neural stimulation to a neural target. The controller is configured to detect laryngeal vibrations or cough using the accelerometer, and is configured to use the neurostimulator and use the detected laryngeal vibrations or the detected cough as an input for programmed neurostimulation therapy , to deliver the programmed neurostimulation therapy.

Description

[0001] priority claim [0002] The benefit of priority to US Provisional Application 61 / 225,832, filed July 15, 2009, which is hereby incorporated by reference, is hereby claimed. technical field [0003] The present application relates generally to medical devices, and more particularly to systems, devices and methods for sensing laryngeal vibrations or coughing. Background technique [0004] It is known to implant long-term electrical stimulators, such as cardiac stimulators, to deliver one or more medical treatments. Examples of cardiac stimulators include implantable cardiac rhythm management (CRM) devices such as pacemakers, implantable cardiac defibrillators (ICD), and implantable devices capable of performing both pacing and defibrillation functions. [0005] CRM devices are implantable devices that provide electrical stimulation to selected heart chambers to treat heart rhythm disorders. For example, an implantable pacemaker is a CRM device that paces the heart wit...
