  • Patent number: 10016145
    Abstract: Electrical activity propagation along an electrode array within a cardiac chamber is reconstructed. Signals are sampled from the electrode array and the signals are plotted in multi-dimensional space with each axis corresponding to a channel in the electrode array. An excursion direction of global activation in the multi-dimensional space is estimated and a change in vectors of the sampled signals over time is determined. Signals with vectors that change over time in the excursion direction are suppressed.

  • Publication number: 20180178007
    Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a tubular member and a distal holding section extending distally of a distal end of the tubular member and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may facilitate vascular delivery of the pacing device to a left side of a patient's heart. In one example, a distal tip portion may extend distal of the distal holding section and may be actuated between a closed and an opened position. When in the closed position, the distal tip portion may have a tip that can puncture or engage an opening in a septum between a left atrium and a right atrium of a patient's heart. Actuating the distal tip portion to an opened position may be utilized to dilate the puncture or opening in the septum.
