  • Patent number: 10653379
    Abstract: The brain appears to have organized cardiac frequency angiographic phenomena with such coherence as to qualify as vascular pulse waves. Separate arterial and venous vascular pulse waves may be resolved. This disclosure states the method of extracting a spatiotemporal reconstruction of the cardiac frequency phenomena present in an angiogram obtained at faster than cardiac frequency. A wavelet transform is applied to each of the pixel-wise time signals of the angiogram. If there is motion alias then instead a high frequency resolution wavelet transform of the overall angiographic time intensity curve is cross-correlated to high temporal resolution wavelet transforms of the pixel-wise time signals. The result is filtered for cardiac wavelet scale then pixel-wise inverse wavelet transformed. This gives a complex-valued spatiotemporal grid of cardiac frequency angiographic phenomena. It may be rendered with a brightness-hue color model or subjected to further analysis.

The system can also be used in conjunction with an advanced patient management system that includes a programmer or repeater capable of gathering information from the implanted device and transmitting the data to a host via a communications network for evaluation at a remote location.

  • Patent number: 9789327
    Abstract: A wearable defibrillation system includes an output device and a motion sensor. The output device emits a sound or a vibration for the patient, who responds by deliberately tapping the system. The motion sensor registers the tapping, and interprets it as a reply from the patient. The reply can be that the patient is conscious, or convey data that the patient enters by tapping the right number of times, or that the patient wants attention, and so on. Since the patient does not need direct access to the wearable defibrillation system for tapping it, he or she can wear it under their other garments, which helps preserve their dignity and privacy.

  • Patent number: 9782089
    Abstract: A system determines measured patient values for use in clinical calculations using an electronic form including, a first area including data fields for presenting values of the parameters associated with a first part of a cardiac catheterization study of a patient and a second area including data fields for presenting values of the parameters associated with a different second part of a cardiac catheterization study of the patient. A user interface enables a user to copy at least one of the parameters comprising a measured value from the first area to the second area as a substitute value eliminating a need for a re-measurement of the value. A calculation processor automatically calculates a cardiac flow value for incorporation in the second area in response to the measured value being copied into the second area.

  • Patent number: 9757036
    Abstract: Methods and systems for producing an electrophysiological map of a heart of a patient are disclosed. An example method may include determining a target location and an orientation of a catheter tip, confirming that the tip is located at the target location, measuring the heart parameter value at each of the target locations, and superimposing a plurality of representations of the heart parameter value. Confirmation that the tip of the catheter is located at a target location can be accomplished by comparing the current location of the tip with the target location, a corresponding heart parameter value being measured at each of the target locations by a heart parameter sensor, and the representations of the heart parameter value being superimposed on an image of the heart at the target location to produce the electrophysiological map.

  • Patent number: 9737269
    Abstract: A patient communicator device provides the ability for non-verbal communication between a patient and medical personnel. The device includes a handgrip module that is held by the patient and a display unit for use by the medical personnel, with a communication link coupling the two components together. The handgrip module is formed of a deformable material and encases a power source (i.e., battery) and a pressure-activated switch. The patient squeezes the handgrip module to close the switch and transmit a signal to the display unit. For example, one squeeze may be used to indicate that everything is fine, two squeezes may be used to indicate that the patient is feeling an uncomfortable amount of pain and needs additional medication. These “squeeze” signals take the form of pulses that are passed to the display unit so that the medical personnel remains apprised of the patient's condition, allowing the patient to communicate regarding issues such as anxiety, pain or discomfort.

  • Patent number: 9655536
    Abstract: The present disclosure uses physiological data, ECG signals as an example, to evaluate cardiac structure and function in mammals. Two approaches are presented, e.g., a model-based analysis and a space-time analysis. The first method uses a modified Matching Pursuit (MMP) algorithm to find a noiseless model of the ECG data that is sparse and does not assume periodicity of the signal. After the model is derived, various metrics and subspaces are extracted to image and characterize cardiovascular tissues using complex-sub-harmonic-frequencies (CSF) quasi-periodic and other mathematical methods. In the second method, space-time domain is divided into a number of regions, the density of the ECG signal is computed in each region and inputted into a learning algorithm to image and characterize the tissues.
