An integrated triad system to measure a patient's blood pressure at different body positions, to instruct the patient when to move from one position to the next to alleviate vascular hypertension based on an algorithm stored in the system calculating blood pressure changes and predictive risk, and to transmit the result to a remote medical location. Using the integrated triad system to perform the test over a period can increase test sensitivity by accommodating the variable onset of the disease.

Diagnostic and therapeutic device for compromised vascular hemodynamics analysis

An apparatus and method are disclosed for acoustically guiding a distal end of a tube within a body. An incident sound pulse is generated and propagated down the tube into the body. A plurality of microphones are located in the tube and are positioned to detect pulses traveling through the tube. A discriminator distinguishes between incident sound pulses and those that are reflected from within the body. The detected sound pulses are processed to provide an indication of the location of the distal end of the tube within the body, to assist with the guidance of the insertion into the body, to estimate dimensions of the body adjacent the distal end of the tube, and to determine if the tube is obstructed.

Miniature acoustical guidance and monitoring system for tube or catheter placement

An apparatus and method is disclosed for acoustically guiding a distal end of a tube within a body. The apparatus and method generates an incident sound pulse in the tube which propagates into the body, detects sound pulses resulting from the incident sound pulse and from reflected sound pulses from within the body, and processes the detected sound pulses to guide insertion of the distal end of the tube within the body. The apparatus and method provides an indication of the position of the distal end of the tube within the body conduit, estimates dimensions of the body conduit adjacent the distal end of the tube, and determines if the tube is obstructed.
