Abstract: A system and method, for obtaining and analyzing vascular data and generating results, that uses vascular test data to determine the state of the vessel. The data and the determinations can be used to generate reports, render diagnoses or identifying ailments, and may do so remotely. The system includes a telemedicine server and may include a number of other modules such as work stations, review tools, data storage modules, etc. The invention allows rapid and efficient analysis of the data, and provides mechanisms for comparing patient data to know or measured normative data sets, remotely if desired, and provides more accurate and less invasive diagnoses based on vascular conditions. The invention permits remote receipt, processing and distribution of the data and diagnoses.

Abstract: The invention relates to systems and methods for assessing blood flow in single or multiple vessels and segments, for assessing vascular health, for conducting clinical trials, for screening therapeutic interventions for effect, for assessing risk factors, for evaluating intracranial pressure and for analyzing the results in a defined manner. The invention enables direct monitoring of therapies, substances and devices on blood vessels, especially those of the cerebral vasculature. Relevant blood flow parameters include mean flow velocity, systolic acceleration, and pulsatility index. Measurement and analysis of these parameters, and others, provides details regarding the vascular health of individual and multiple vessels and a global analysis of an individual's overall vascular health. The invention is applicable as both a system and method for monitoring and improving the design, performance, marketing and use of vascular stents.

Abstract: The present invention relates generally to systems and methods for assessing blood flow in blood vessels, for assessing vascular health, for conducting clinical trials, for screening therapeutic interventions for adverse effects, and for assessing the effects of risk factors, therapies and substances, including therapeutic substances, on blood vessels, especially cerebral blood vessels, all achieved by measuring various parameters of blood flow in one or more vessels and analyzing the results in a defined matter. The relevant parameters of blood flow include mean flow velocity, systolic acceleration, and pulsatility index. By measuring and analyzing these parameters, one can ascertain the vascular health of a particular vessel, multiple vessels and an individual. Such measurements can also determine whether a substance has an effect, either deleterious or advantageous, on vascular health. In one of many embodiments, the present invention further provides an expert system for achieving the above.

Abstract: The present invention comprises methods for detecting, assessing, diagnosing, and pre-diagnosing sleep apnea, and for assessing the efficacy of a treatment for sleep apnea. Methods for the detection, assessment, diagnosis and pre-diagnosis (screening) of sleep apnea and the assessment of a treatment for sleep apnea according to the present invention may be performed in the absence of a sleep study. The patients subject to these methods may remain awake during their performance. The invention may be applied to other vascular conditions besides sleep apnea, wherein the sleep apnea methods described herein are example methods for the application of the present invention to the detection, assessment, diagnosis and pre-diagnosis (screening) of other vascular conditions.

Abstract: A gravity fed, pour-through water filtration device includes a chamber housing a spiral filter including a biocidal material and an annular holding chamber. Several porous separator disks, a volume of filtration media, and a cyst membrane are positioned beneath the spiral filter and holding chamber. The device is effective in significantly reducing the number of bacteria, viruses and cysts present in the filtrated water.
