Acceleration Sensors For Recording Of Triggered Respiratory Signals In Neurostimulators

Abstract

A respiration implant system includes a pacing processor configured to receive a respiration signal and a movement signal to generate a respiration pacing signal that is synchronized with the detected respiration activity. The pacing processor is configured to optimize system power consumption over time by using multiple respiration sensing modes that reflect activity of the movement signal over time.

Description

[0001]This application claims priority from U.S. Provisional Patent Application 61 / 975,066, filed Apr. 4, 2014, which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The present invention relates to respiration implant systems such as implantable respiration pacing systems and sleep apnea treatment systems.BACKGROUND ART[0003]The larynx is located in the neck and is involved in breathing, producing sound (speech), and protecting the trachea from aspiration of food and water. FIG. 1A shows a coronal section view and FIG. 1B shows a transverse section view of the anatomy of a human larynx including the epiglottis 101, thyroid cartilage 102, vocal folds 103, cricothyroid muscle 104, arytenoid cartilage 105, posterior cricoarytenoid muscle (PCAM) 106, vocalis muscle 107, cricoid cartilage 108, recurrent laryngeal nerve (RLN) 109, transverse arytenoid muscle 110, oblique arytenoid muscle 111, superior laryngeal nerve 112, and hyoid bone 113.[0004]The nerves and m...

AI Technical Summary

Benefits of technology

The patent describes respiration implant systems for patients with breathing issues. These systems use multiple power management modes to detect and synchronize with the implanted patient's breathing activity and movement. A pacing processor generates a respiration pacing signal that is delivered to the patient's respiration neural tissue to promote breathing. The system also detects the patient's breathing effort to control the pulse rate, width, and amplitude of the pacing signal. Overall, these systems provide a more efficient and effective means to help patients breathe.

Problems solved by technology

This serious situation usually requires surgical treatment of the bilateral vocal cord paralysis such as cordotomy or arytenoidectomy, which subsequently restrict the voice and puts at risk the physiologic airway protection.
