First Claim
Patent Images
1. An apparatus comprising:
- an implantable cardiac rhythm/function management device comprising;
a cardiac contractility modulation (CCM) therapy circuit configured to deliver a CCM therapy including a non-stimulatory electrical energy during a refractory period of the heart;
an adverse event detector circuit including a CCM stressor detector circuit configured to detect a CCM stressor condition for disabling the CCM therapy, wherein the CCM stressor condition includes a detection of sleep disordered breathing; and
a controller circuit, coupled to the CCM therapy circuit and the adverse event detector circuit, the controller circuit configured to obtain or provide information about a CCM condition and information about an adverse event, the controller circuit configured to adjust the CCM therapy using the information about the adverse event from the adverse event detector circuit, wherein the controller circuit is configured to disable the CCM therapy when or the sleep disordered breathing is detected.

Abstract
An implantable cardiac rhythm/function management system integrates cardiac contractility modulation (CCM) and one or more other therapies, such as to preserve device safety, improve efficacy, enhance sensing and detection, or enhance therapy effectiveness and delivery. Examples of the one or more other therapies can include pacing, defibrillation/cardioversion, cardiac resynchronization therapy (CRT), or neurostimulation.
