Leadless cardiac pacemaker and system

Abstract

In a cardiac pacing system, a leadless cardiac pacemaker is configured for implantation in electrical contact with a cardiac chamber and configured for leadless pacing.

Description

Background technique [0001] Cardiac pacing electrically stimulates the heart when the heart's natural pacemaker and / or conduction system cannot provide the patient with the desired synchronized atrial and ventricular contractions at the proper rate and interval. Thus, bradycardia pacing has relieved symptoms and even provided life support for countless patients. Cardiac pacing can also perform electrical overdrive stimulation to suppress or convert tachyarrhythmias, additionally relieve symptoms and prevent or terminate arrhythmias that can lead to sudden cardiac death. [0002] Cardiac pacing is typically performed by a pulse generator implanted subcutaneously or submuscularly in or near the patient's chest region. The generator is typically connected to the proximal end of one or more implanted leads, the distal end of which includes one or more electrodes for alignment with the inner or outer walls of adjacent heart chambers. Leads have one or more insulated electrical co...

Problems solved by technology

Wake-up techniques complicate the telemetry protocol, which often results in longer connection times

In addition, wake-up techniques use relatively large antennas or coils, which is undesirable and contradictory for compactly implanted medical devices in the body
