摘要:
A leadless pacemaker for pacing a heart of a human includes a hermetic housing and at least two electrodes on or near the hermetic housing. The at least two electrodes are configured to deliver energy to stimulate the heart and to transfer information to or from at least one external device.
摘要:
A cardiac pacing system comprising one or more leadless cardiac pacemakers configured for implantation in electrical contact with a cardiac chamber and configured to perform cardiac pacing functions in combination with a co-implanted implantable cardioverter-defibrillator (ICD). The leadless cardiac pacemaker comprises at least two leadless electrodes configured for delivering cardiac pacing pulses, sensing evoked and/or natural cardiac electrical signals, and bidirectionally communicating with the co-implanted ICD.
摘要:
A leadless cardiac pacemaker that does not require a separate hermetic housing surrounding the battery and electronics compartments is provided. The cardiac pacemaker can include a battery disposed in a battery housing and a set of electronics disposed in an electronics housing. In some embodiments, the battery housing and the electronics housing can comprise an external surface of the pacemaker. The pacemaker can include a first set of welds separating the battery from the set of electronics, and a second set of welds separating the set of electronics and the battery from an exterior of the housing. Various embodiments for achieving dual-redundant welds are also provided.
摘要:
A leadless cardiac pacemaker configured for implantation in electrical contact with a left ventricular cardiac chamber and configured for leadless triggered left-ventricular pacing for cardiac resynchronization therapy (CRT) in response to conducted signals from a pulse generator.

摘要:
A biostimulator system comprises one or more implantable devices and an external programmer configured for communicating with the implantable device or devices via bidirectional communication pathways comprising a receiving pathway that decodes information encoded on stimulation pulses generated by ones of the implantable device or devices and conducted through body tissue to the external programmer.
摘要:
A leadless cardiac pacemaker comprises a housing, a plurality of electrodes coupled to an outer surface of the housing, and a pulse delivery system hermetically contained within the housing and electrically coupled to the electrode plurality, the pulse delivery system configured for sourcing energy internal to the housing, generating and delivering electrical pulses to the electrode plurality. The pacemaker further comprises an activity sensor hermetically contained within the housing and adapted to sense activity and a processor hermetically contained within the housing and communicatively coupled to the pulse delivery system, the activity sensor, and the electrode plurality, the processor configured to control electrical pulse delivery at least partly based on the sensed activity.
