Abstract
A leadless cardiac pacemaker device is configured to provide HIS bundle pacing and contains a housing having a tip, a first electrode arranged on the housing in the vicinity of the tip, the first electrode being configured to engage with intra-cardiac tissue, and a second electrode arranged on the housing at a distance from the tip of the housing. A processor is enclosed in the housing and operatively connected to the first electrode and the second electrode. The processor is configured to process a reception signal received by at least one of the first electrode and the second electrode and to generate a pacing signal to be emitted using at least one of the first electrode and the second electrode.
Core Innovation
The invention provides a leadless cardiac pacemaker configured to provide conduction system pacing or HIS bundle pacing. The leadless cardiac pacemaker includes a housing having a tip and a far end opposite the tip, with a first electrode disposed on the housing in an area of the tip for engaging with intra-cardiac tissue, a second electrode disposed on the housing at a distance from the tip, and a third electrode disposed on the housing in an area in the vicinity of the far end.
A processor enclosed in the housing processes reception signals received by at least one of the first electrode and the second electrode and generates a pacing signal to be emitted using at least one of the first electrode and said second electrode. The reception signal is processed as at least one of a second signal vector sensed between the first electrode and the third electrode and a third signal vector sensed between the second electrode and the third electrode.
The processor alternates between processing at least one of the second signal vector sensed between the first electrode and the third electrode and the third signal vector sensed between the second electrode and the third electrode, and generating the pacing signal to be emitted using at least one of the first electrode and the second electrode.
Claims Coverage
The independent claim covers a leadless cardiac pacemaker with three electrodes on a leadless housing and a processor that processes reception signals as sensed signal vectors and alternates between those vectors while generating pacing signals. Dependent claims further narrow fixation, electrode form, selection among multiple first electrodes, communications of vector information, and processing of vectors for atrial and ventricular detection.
Leadless housing electrode arrangement for conduction system pacing or HIS bundle pacing
A leadless cardiac pacemaker device comprising a housing having a tip and a far end opposite said tip, a first electrode disposed on said housing in an area of said tip configured to engage with intra-cardiac tissue, a second electrode disposed on said housing at a distance from said tip, and a third electrode disposed on said housing in an area in the vicinity of said far end.
Processor processing reception signals to generate pacing signals
A processor enclosed in said housing and operatively connected to said first electrode and to said second electrode, wherein said processor is configured to process a reception signal received by at least one of said first electrode and said second electrode and to generate a pacing signal to be emitted using at least one of said first electrode and said second electrode.
Signal-vector reception between electrode pairs and alternation
Wherein said processor is configured to process, as the reception signal, at least one of a second signal vector sensed between said first electrode and said third electrode and a third signal vector sensed between said second electrode and said third electrode, and wherein said processor is configured to alternate between processing at least one of the second signal vector sensed between said first electrode and said third electrode and the third signal vector sensed between said second electrode and said third electrode and generating the pacing signal to be emitted using at least one of said first electrode and said second electrode.
Fixation device at the tip of the housing to secure to intra-cardiac tissue
A leadless cardiac pacemaker device that additionally includes a fixation device with at least one fixation element located at the tip of the housing to secure the device to intra-cardiac tissue.
Selection among multiple first electrodes for reception and pacing
A leadless cardiac pacemaker device selects at least one of multiple first electrodes on its housing near the tip to receive reception signals and emit pacing signals.
Circumferential electrode ring as the second electrode
A leadless cardiac pacemaker device is configured so that its second electrode is an electrode ring that extends circumferentially around the device housing.
Communication interface transmitting information relating to a signal vector
The claim covers a leadless cardiac pacemaker device that includes a communication interface to transmit a communication signal carrying information about a first signal vector to an external device outside the human body.
Processing signal vectors to detect atrial and ventricular activity
The leadless cardiac pacemaker device includes a processor configured to process the second and third signal vectors to detect atrial and ventricular activity, respectively.
The inventive coverage centers on a leadless electrode arrangement with a processor that processes reception signals as electrode-pair signal vectors between the first-third and second-third electrodes and alternates between processing those vectors while generating pacing signals using at least one of the first and second electrodes, with further limitations for fixation, electrode-ring form, multiple first electrode selection, external communication of signal-vector information, and mapping vectors to atrial and ventricular detection.
