Summary

This is a prospective, multi-center, two-arm, randomized trial to quantify the performance of the EchoMark®/EchoSure® System for AVF diagnostic ultrasound when used under a protocol of biweekly use for assessing fistula maturation and reducing time to Clinical Maturation.

Conditions

Interventions

DEVICE

EchoMark/EchoSure

Subjects assigned to the Diagnostic Arm will have the EchoMark implanted at the time of AVF creation. The subject will return every 2 weeks for a follow-up assessment to include an EchoSure scan until fistula maturation and/or permanent access use is achieved. The EchoSure scans are to be reviewed by the investigator(s) or delegated study staff and aid in the determination when a further assessment, including a physical exam, is required to determine cannulation clearance or if an intervention(s) may be required to prevent failure of fistula maturation. All physical exams will include assessing the fistula for bruit and thrill. The subject's medical history will be reviewed at each visit and will include all interventions, cannulation attempts, and adverse event reporting.

PROCEDURE

Standard of Care

Subjects are assessed using standard of care per KDOQI guidelines, which includes a physical exam at the 2-week follow-up visit and at the 4-6-week follow-up visit. All follow-up visits will include an assessment of adverse events and medical history review to include all interventions, cannulation attempts, and laboratory results. If evaluation yields an abnormal finding, subjects will undergo a Duplex ultrasound assessment and treatment under the institution's standard of care. All SOC Arm subjects will be followed per the institution's standard of care until fistula maturation occurs and/or permanent access use is achieved but no more frequently than once per month.
