VADOplex Critical Limb Ischemia Study

Phase 2
Conditions
Peripheral Artery Disease
Quality of Life
Wound Healing
Interventions
Device: VADOplex system
Registration Number
NCT02034539
Lead Sponsor
Asklepios Kliniken Hamburg GmbH
Brief Summary

In patients with critical limb ischemia (CLI) and foot ulcers wound healing is an important goal which can normally only be achieved after sufficient treatment of the underlying ischemia (revascularization either by an operation, e. g. bypass, or a catheter intervention). After successful revascularization everything should be done to improve wound healing because this regularly takes weeks up to several months. One possibility to speed up healing could be treatment with the VADOplex device which delivers an automatic intermittent painless compression of the sole of the foot thereby increasing perfusion of the leg. This system can be easily operated by patients themselves and at home.

Our goal is to prove that the VADOPlex system accelerates healing up and improves quality of life.
