Abstract:
An embodiment of the invention provides a method for determining a patient-specific probability of renal transplant survival. The method collects clinical parameters from a plurality of renal transplant donor and patient to create a training database. A fully unsupervised Bayesian Belief Network model is created using data from the training database; and, the fully unsupervised Bayesian Belief Network is validated. Clinical parameters are collected from an individual patient/donor; and, such clinical parameters are input into the fully unsupervised Bayesian Belief Network model via a graphical user interface. The patient-specific probability of disease is output from the fully unsupervised Bayesian Belief Network model and sent to the graphical user interface for use by a clinician in pre-operative organ matching. The fully unsupervised Bayesian Belief Network model is updated using the clinical parameters from the individual patient and the patient-specific probability of transplant survival.
Abstract:
A medical monitoring device for monitoring electrical signals from the body of a subject is described. The medical monitoring device monitors electrical signals originating from a cardiac cycle of the subject and associates each cardiac cycle with a time index. The medical monitoring device applies a forward computational procedure to generate a risk score indicative of hyperkalemia, hypokalemia or arrhythmia of the subject. The medical monitoring device can adjust the forward computational procedure based upon clinical data obtained from the subject.
Abstract:
The invention provides methods for diagnosing and treating asthma in subjects in need thereof but can be applied to other conditions where abnormal electrophysiology underlies dysfunctional organ contractility.
Abstract:
The present invention provides a diagnostic method comprising continuously monitoring and transmitting urine output and urine flow rates of a catheterized patient to means which correlate the same with at least one of renal perfusion, renal function, fluid status, polyuria, oleguria, hypoperfusion, hemorrhage shock and GFR.

Abstract:
A heart monitoring system for a person includes one or more wireless nodes; and a wearable appliance in communication with the one or more wireless nodes, the appliance monitoring vital signs.
Abstract:
A magnetic resonance imaging (MRI) system semi-automatically performs non-contrast magnetic resonance angiography (MRA). An operator display and control input port configures the MRI system to effect semi-automated non-contrast MRA imaging with spatially selective tag and venous suppression RF pulses and/or black blood time interval (BBTI) parameters in a non-contrast MRA data acquisition sequence where such parameters are automatically determined within predetermined, respectively corresponding, spatial regions of patient anatomy. Such automatically determined non-contrast MRA imaging parameters may be entirely automatically set and used or, alternatively, may be displayed to an operator for acceptance and/or change before being used.
Abstract:
A method for measuring a glomerular filtration rate of a mammalian subject comprises a source of reporter and marker fluorescent molecules. The fluorescent molecules are introduced into the vascular system of the mammalian subject. Over a period of time, a measurement of the intensities of the reporter and marker fluorescent molecules is taken. A ratio is calculated to determine the glomerular filtration rate.
Abstract:
A system for treatment includes a focused ultrasound energy source for placement outside a patient, wherein the focused ultrasound energy source is configured to deliver ultrasound energy towards a blood vessel with a surrounding nerve that is a part of an autonomic nervous system inside the patient, and wherein the focused ultrasound energy source is configured to deliver the ultrasound energy from outside the patient to the nerve located inside the patient to treat the nerve.
Abstract:
A catheter includes a flexible shaft having a length sufficient to access a patient's renal artery relative to a percutaneous access location. A treatment arrangement is provided at a distal end of the shaft and configured for deployment in the renal artery. The treatment arrangement includes an ablation arrangement configured to deliver renal denervation therapy. An occlusion arrangement is configured for deployment in the renal artery and for altering blood flow through the renal artery during or subsequent to renal denervation therapy delivery. A monitoring unit is configured for monitoring for a change in one or more physiologic parameters influenced by the renal denervation therapy. The monitoring unit is configured to produce data useful in assessing effectiveness of the renal denervation therapy based on the physiologic parameter monitoring.
