Claims38
A method of treating a subject comprising:
- (a) sensing an onset of the subject's expiratory phase of breathing;
- and (b) delivering a stimulus to the subject's thorax or abdomen during at least part of the expiratory phase of breathing in response to said sensing, said stimulus effective to cause a contraction in the subject's abdominal muscle so as to assist the subject with ventilation, wherein at least one of the sensing and delivering is carried out by one or more implanted sensors and/or implanted device adapted to deliver a stimulus.
An apparatus comprising:
- (a) one or more sensors suitable for detecting when a subject is exhaling;
- and (b) a device adapted to deliver a stimulus to the subject's thorax or abdomen during at least part of an expiratory phase of the subject's breathing in response to a signal generated by said one or more sensors, said stimulus effective to cause a contraction in the subject's abdominal muscle, wherein the apparatus is at least in part implantable in the subject's thorax or abdomen.
