Abstract: Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.

Abstract: A sleeve or sheath includes a body having a top opening. The body covers a handheld oximeter probe or a portion of the probe. The sleeve has a shape that approximately matches the oximeter probe or portion of the probe, which is covered by the sleeve. The sleeve has a top opening that allows a user to slide the oximeter probe into the sleeve. The sleeve is transparent to radiation emitted and collected by the oximeter probe. The sleeve is formed of a material that prevents patient tissue, fluid, viruses, bacteria, and fungus from contacting the covered portions of the oximeter probe. The sleeve leaves the probe relatively sterile after use so that little or no clearing of the probe is required for a subsequent use, such as when the probe is covered with a new, unused sleeve.

Abstract: Systems and methods for blood pressure measurement (BP) based on photoplethysmogram (PPG) data and electrocardiogram (ECG) data an initial baseline BP from a reliable source. A force is cyclically applied to a PPG sensor and the PPG pulse data is recorded and analyzed to determine a PPG-pulse-peak value. The initial baseline MAP is used to configure a MAP model. Additionally, a pre-determined PTT model utilizing PPG and ECG data along blood vessel parameters and baseline BP are initialized to generate a BP. Subsequent BP measurements use the same process of determining PPG-pulse-peak values, the initialize MAP model and pre-determined PTT model to determine a new BP value.
