Patent

CA 2501948

The invention is directed to an implantable medical device that stimulates a nerve associated with respiration. The nerve may, for example be a phrenic nerve, and the stimulation may cause a diaphragm of the patient to contract. The implantable medical device receives a signal that indicates a need for increased cardiac output and stimulates the nerve in response to the signal. The implantable medical device may receive such a signal by, for example, detecting a ventricular tachyarrhythmia, sensing a pressure that indicates a need for increased cardiac output, or receiving a signal from a patient via a patient activator. Stimulation of the nerve may increase cardiac output of a beating or defibrillating heart

L'invention concerne un dispositif médical implantable qui stimule un nerf associé à la respiration. Le nerf peut être, par exemple, le nerf phrénique et la stimulation peut entraîner la contraction du diaphragme du patient. Le dispositif médical implantable reçoit un signal qui indique un besoin en sortie cardiaque améliorée et stimule le nerf en réponse au signal. Le dispositif médical implantable peut recevoir ledit signal, par exemple, par détection d'une tachyarythmie ventriculaire, par détection de la pression qui indique un besoin en sortie cardiaque améliorée, ou par réception d'un signal provenant d'un patient par l'intermédiaire d'un activateur pour patient. La stimulation du nerf peut augmenter la sortie cardiaque d'un corps qui bat ou défibrille.
