  • MINIMALLY INVASIVE DEVICE WITH SPECTROPHOTOMETER
    Publication number: 20240041328
    Abstract: A minimally invasive spectrophotometric system. In some embodiments, the system includes a minimally invasive device and a spectrophotometer. The spectrophotometer may include: a transmitting fiber, a receiving fiber, and a head. The head of the spectrophotometer may include: a light source connected to the transmitting fiber and a photodetector connected to the receiving fiber. A portion of the transmitting fiber may be in an insertion tube of the minimally invasive device, and a portion of the receiving fiber may be in the insertion tube of the minimally invasive device. The head of the spectrophotometer may occupy a volume of less than 300 cubic centimeters.

  • Systems and methods to determine HR, RR and classify cardiac rhythms based on atrial IEGM and atrial pressure signals
    Patent number: 10945614
    Abstract: Systems, devices and methods described herein can be used to monitor and treat cardiovascular disease, and more specifically, can be used to determine heart rate (HR), determine respiration rate (RR) and classify cardiac rhythms based on atrial intracardiac electrogram (IEGM) and atrial pressure (AP) signals. The atrial IEGM and AP signals are subject to spectrum transforms to obtain an atrial IEGM frequency spectrum and an AP frequency spectrum. Based on peaks in the atrial IEGM and AP frequency spectrums measures of HR and RR are determined, and arrhythmias are detected and/or arrhythmia discrimination is performed.
