Inclusion Criteria

• Subjects over 18 years, willing and able to provide written informed consent.
• Subjects able to wear the Amadeus device and follow the requirements of the clinical investigation plan
• Subjects who have an ankle to brachial pressure index (ABPI) of ABPI >0.8
• Subjects with chronic lower limb oedema (i.e. CEAP classification of C3, C4 or C5 1.)

Exclusion Criteria

• Subjects with a history of skin sensitivity to any of the components of the study product.

• Subjects who have previously been entered into the study before

• Subjects who have a history of Deep Vein Thrombosis (DVT) within the last 6 months

• Subjects who have an active leg ulcer (i.e. CEAP classification of C6 1).

• Subjects with active cardiac disease or significant history of cardiac disease (including history of myocardial infarction, heart failure, valvular disease, arrhythmia and those with a pacemaker or have previously had a pacemaker).

Arm && Interventions

Group	Intervention	Description
Profile C	Prototype device(unnamed)-A battery operated inflatable pneumatic cuffs	Foot 50 mmHg, ankle 50 mmHg, mid-calf 45 mmHg, upper calf 40 mmHg
Profile A	Placebo - No device worn	No device worn
Profile B	Prototype device(unnamed)-A battery operated inflatable pneumatic cuffs	Foot 40 mmHg, ankle 40 mmHg, mid-calf 35 mmHg, upper calf 30 mmHg
Profile D	Prototype device(unnamed)-A battery operated inflatable pneumatic cuffs	Foot 60 mmHg, ankle 60 mmHg, mid-calf 55 mmHg, upper calf 50 mmHg

Primary Outcome Measures

Name	Time	Method
The nature and frequency of adverse events
Distal arterial flow

Secondary Outcome Measures

Name	Time	Method
Volume reduction will be measured by recording limb volume at the start and end of each profile for both legs. The test leg will be compared to baseline and the contralateral leg. Comfort during wear will be recorded on completion of each profile
