Brief summary
This study in venous leg ulcer (VLU) patients will evaluate the use of Cirvo™ therapy for the treatment of VLU when applied for a minimum of two hours daily for up to 12 weeks.
Interventions
The Cirvo(TM) (also referred to as the Radial Medical Compression System) is a mobile wearable medical device that applies graded intermittent mechanical sequential compression for the treatment of venous leg ulcers (VLU).
