  • Patent number: 11400275
    Abstract: A blood pump system for persistently increasing the overall diameter and lumen diameter of peripheral veins and arteries by persistently increasing the speed of blood and the wall shear stress in a peripheral vein or artery for a period of time sufficient to result in a persistent increase in the overall diameter and lumen diameter of the vessel is provided. The blood pump system includes a blood pump, blood conduit(s), a control system with optional sensors, and a power source. The pump system is configured to connect to the vascular system in a patient and pump blood at a desired rate and pulsatility. The pumping of blood is monitored and adjusted, as necessary, to maintain the desired elevated blood speed, wall shear stress, and desired pulsatility in the target vessel to optimize the rate and extent of persistent increase in the overall diameter and lumen diameter of the target vessel.

  • Patent number: 11399763
    Abstract: Conduction velocity information for a cardiac region can be used to map the cardiac muscle fiber orientation of that region. In particular, for a plurality of locations within the cardiac region, a relationship between a local conduction velocity, a maximum local conduction velocity within the region, and a minimum local conduction velocity within the region is used to determine the cardiac muscle fiber orientation at the respective location. Even more particularly, when the local conduction velocity at the respective location equals the maximum local conduction velocity, the cardiac muscle fiber orientation is parallel to a direction of a conduction velocity vector at the respective location, and when the local conduction velocity at the respective location equals the minimum local conduction velocity, the cardiac muscle fiber orientation is perpendicular to a direction of a conduction velocity vector at the respective location.

  • Patent number: 11278233
    Abstract: Methods, apparatus, and systems for medical procedures are disclosed herein and include detecting points of an intra-cardiac area that exhibits abnormal activations, such as local abnormal ventricular activations (LAVAs). Points that exhibit such abnormal activations may be referred to as seed points that are identified during a first step of the process disclosed herein. The seed points may be identified using one or more inputs such as unipolar and bipolar mapping channels, body surface ECGs, past activations, neighboring points and the like during the first step which prioritizes high specificity over sensitivity. During a second step which prioritizes high sensitivity, electrical activations of neighboring points near the seed points are analyzed to determine if the activations are similar (e.g., have a similar time) as the abnormal activations corresponding to the corresponding seed points.

  • Patent number: 11229393
    Abstract: Cardiac activity (e.g., a cardiac electrogram) is analyzed for local abnormal ventricular activity (LAVA), such as by using a LAVA detection and analysis module incorporated into an electroanatomical mapping system. The module transforms the electrogram signal into the wavelet domain to compute as scalogram; computes a one-dimensional LAVA function of the scalogram; detects one or more peaks in the LAVA function; and computes a peak-to-peak amplitude of the electrogram signal. If the peak-to-peak amplitude does not exceed a preset amplitude threshold, then the module can compute one or more of a LAVA lateness parameter for the electrogram signal using one of the one or more peaks detected in the LAVA function and a LAVA probability parameter for the electrogram signal.
