Abstract
The invention disclosed here relates in general to the field of medical devices. In particular, to devices and methods for improving the clinical outcome of patients suffering from cardiac dysrhythmias without cardiac arrest. This method and/or device integrates mechanical, pneumatic, acoustic and/or electrophysiologic capabilities with electrical countershock or pacing capabilities such that the probability of successful cardioversion or pacing is increased. The sequence, forces, and electrical properties of the subsystems can be computer controlled and adjusted in response to biomarker inputs.
Claims18
A Cardiac Electrical Therapy Efficacy Enhancement System (CETEES) to improve the efficacy of acute electrical therapies for patients suffering cardiac dysrhythmias with retained hemodynamics, the CETEES comprising:
- a Transthoracic Cardioverter Pacer (TCP);
- an electrode contact force enhancer;
- an exhalation band;
- a transcutaneous abdominal muscle electrical stimulator adapted to stimulate an abdominus rectus muscle to trigger exhalation;
- a transcutaneous myocardium vibratory energy emitter adapted to emit acoustic, ultrasound or vibratory energy towards a myocardium;
- a transcutaneous vagus nerve electromagnetic energy emitter adapted to stimulate a vagus nerve;
- a CETEES body that includes an inelastic outer shell, the CETEES body providing a housing to contain and maintain the location of at least the electrode contact force enhancer, the exhalation band, and the vibratory energy emitter;
- and
- a controller that controls and synchronizes the cardioverter or pacemaker, the contact force enhancer, the exhalation band, the abdominal muscle electrical stimulator, the myocardium vibratory energy emitter, and the vagus nerve electromagnetic energy emitter so that in a first step the controller controls the myocardium vibratory energy emitter to emit vibratory energy and the vagus nerve electromagnetic energy emitter to emit electromagnetic energy, and then in a second step, controller controls the exhalation band to force exhalation, the muscle electrical stimulator to stimulate, and the electrode contact force enhancer to apply force to electrodes of the cardioverter or pacemaker, and then in a third step the controller controls the cardioverter or pacemaker to delivers a defibrillation shock while the myocardium vibratory energy emitter is emitting vibratory energy, the vagus nerve electromagnetic energy emitter is emitting electromagnetic energy, the exhalation band is forcing exhalation, and the electrode contract fore enhancer is applying force to the electrodes.
A Cardiac Electrical Therapy Efficacy Enhancement System (CETEES) to improve the efficacy of acute electrical therapies for patients suffering cardiac dysrhythmias with retained hemodynamics, the CETEES comprising:
- a Transthoracic Cardioverter Pacer (TCP);
- an electrode contact force enhancers adapted to press on a TCP electrode;
- and
- a controller that synchronizes the TCP and the electrode contact force enhancer so that the TCP administers an electrical discharge in synchrony with the application of force to the TCP electrode by the electrode contact force enhancer.
A controller for a Cardiac Electrical Therapy Efficacy Enhancement System (CETEES) to improve the efficacy of electrical therapies in patients suffering cardiac dysrhythmias with retained hemodynamics, the controller comprising:
- a data input module that inputs data from afferent sensors;
- an output module that provides instructions to effector subsystems;
- a TCP control module;
- an electrode contact pressure enhancing subsystem control module;
- and
- a synchronization module that synchronizes the TCP control module with the electrode contract pressure enhancing subsystem control module so that the TCP control module instructs a TCP to deliver a shock after the electrode contract pressure enhancing subsystem control module has instructed the electrode contract pressure enhancing subsystem to increase electrode contact pressure.
