  • Patent number: 10828109
    Abstract: A method for planning treatment of a stenosis in a vascular segment includes providing a geometric description of the vascular segment on a computer and determining a course of a hemodynamic parameter of the vascular segment along the vascular segment based on the geometric description provided by the computer. The computer calculates a mathematical derivative of the hemodynamic parameter over the length of the vascular segment along the vascular segment. At least one length section is specified for the vascular segment, and a value of the hemodynamic parameter in a distal end region of the vascular segment is simulated for a treatment device introduced virtually into the specified length section as a function of the mathematical derivative. The treatment of the stenosis including the introduction of the treatment device into the specified length section is planned as a function of the simulated value for the hemodynamic parameter.

  • Patent number: 10820820
    Abstract: Described herein are implantable systems and devices, and methods for use therewith, that distinguish between different signal components of interest in sensed physiologic signals with high sensitivity and specificity. Such a method can include obtaining a sensed signal using an IMD and using a plurality of different filters that are parallel to one another to simultaneously filter the sensed signal, and/or copies thereof, to produce different filtered signals. Where each filter has a respective passband that does not substantially overlap with the passband(s) of the other filter(s), each of the different filtered signals will be indicative of different frequency content of the sensed signal. Additionally, amplitudes of temporally aligned peaks in at least two of the different filtered signals can be detected, and one or more peaks of the sensed signal can be classified based on the detected amplitudes of the temporally aligned peaks in the different filtered signals.
