A laryngeal pacemaker is configured for external placement on skin of a patient to produce respiration stimulation signals. An implantable stimulation electrode delivers the respiration stimulation signals to adjacent target neural tissue for vocal fold abduction during respiration of the recipient patient. A triaxial accelerometer produces a body motion signal reflecting energy expenditure of the recipient patient. A respiration sensor includes a flexible skin-transferrable printed tattoo electrode having a tetrapolar configuration for impedance pneumography measurement to produce a sensed respiration signal for the laryngeal pacemaker. The respiration sensor is configured for transfer and release by guided placement from a sensor applicator to the skin at the angulus sterni of the recipient patient. And the laryngeal pacemaker is configured to interpret the body motion signal and the sensed respiration signal to make a real time determination of respiratory phase and frequency for adaptively adjusting the respiration stimulation signals accordingly.

A medical device comprises a tube (12) having and at least one lumen, a flexible body (102) including a stimulation array (114) to provide an electrical charge for stimulating tissue, an electrical connection to electrically couple the stimulation array to a power source and positioned on the flexible body proximal to the stimulation array, and an electronic component positioned between the stimulation array (114) and the power source. The electronic component includes a memory and a processor configured to implement programmable code stored on the memory. The flexible body (102) is configured to cover at least a portion of the longitudinal length of the tube (12) such that the stimulation array (114) is disposed about an exterior of the tube.

Devices, systems, and methods configured to treat disease using electrical stimulation and therapeutic agents are disclosed herein. In some embodiments, a device of the present technology comprises a first elongated shaft configured to deliver supplemental nutrition to a patient suffering from dysphagia and a second elongated shaft configured to slidably receive the first elongated shaft. The second elongated shaft can include one or more conductive elements configured to deliver electrical stimulation to nerves at a first treatment site in a pharynx of the patient. In some embodiments, the second elongated shaft includes one or more therapeutic elements carrying a therapeutic agent configured to be positioned at or adjacent a second treatment site with a pooled secretion in the patient's pharynx. The therapeutic agent can be configured to prevent or inhibit colonization of the pooled secretion by one or more pathogens. In some embodiments, the second elongated shaft includes a lumen fluidically coupled to an aperture extending through a sidewall of the elongated shaft. The aperture can be configured to be positioned at or adjacent the second treatment site with the pooled secretion. The lumen and aperture can be configured to transport fluid therethrough along a longitudinal dimension of the device to deliver a therapeutic agent to the second treatment site and / or withdraw the pooled secretion from the second treatment site into the lumen.
