Official title
New Doppler Instrument for Preventing Impending Access-Graft Failure Randomized Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This research study aims to show that a newly developed investigational Doppler instrument can reliably measure blood flow in dialysis access grafts, to see if a decrease in the flow may be a sign of impending graft failure and also to see if there is evidence that by monitoring the flow in these grafts their lives may be extended. The new investigational device is to be known as FloMon; this is an ultrasonic device that provides blood flow measurements from a small probe placed in a noninvasive manner above the graft or blood vessel. The instrument is being developed so that it may help give insight to on-coming graft failure which may be prevented. The FloMon is an extension of a previously Food and Drug Administration (FDA) cleared instrument, Echoflow-A, which had been used in a similar study as this one. The Echoflow-A is similar to this device in all respects with the exception of design and calculation of measurement. The FloMon compared to the Echoflow-A is better ergonomically designed and reads flow readings in about 2 minutes versus twice the time necessary to take similar measurements using the Echoflow-A.
