A Clinical Study to Assess a Compression Device in Patients With Venous Leg Ulcers

The purpose of this study is to evaluate the product performance of a new adjustable
compression system for the treatment of venous leg ulcers. The new compression system
consists of a compression stocking and and adjustable compression sleeve. It will be used
over primary dressings to provide compression that is beneficial to the healing of venous
leg ulcers.

> 2cm apart from any other ulcer?

3. Does the subject have an ulcer size between 1cm2 and 12cm2?

4. Does the subject have an ABPI between 0.8 and 1.3 that was taken within the past 28
days?

5. Is the subject ambulatory?

6. Is the subject or family member willing to self-manage the venous leg ulcer therapy
at home in collaboration with the medical staff, including the ability to properly
readjust the closure straps as indicated by tension indicators, and apply new
dressings when needed?

7. Is the subject able to understand questionnaire items and action items (e.g., Subject
Diary)?

8. Is the subject willing to give written informed consent, including permission to take
photographs of the study leg?

Exclusion Criteria:

1. Does the subject have severe arterial occlusive disease?

2. Does the subject have decompensated heart insufficiency NYHA Class IV, ACC.AHA Stage
D?

3. Does the subject have septic phlebitis?

4. Does the subject have severe deep vein thrombosis (phlegmasia cerulea dolens) and
other conditions contraindicated according to established guidelines and local
procedures?

5. Does the subject have known hypersensitivity to any of the component materials?

6. Does the subject have a suspected clinical infection of the ulcer or any other
systemic infection (requiring antibiotics)?

inclusion?

8. Does the subject have a hospital stay planned for the 12 weeks following inclusion?

9. Does the subject have a suspected or confirmed cancerous ulceration?

10. Does the subject have severe peripheral sensitive neuropathy?

11. Is the subject participating in any other prospective study interfering with this
study?

12. Does the subject have any medical condition which in the professional opinion of the
investigator disqualifies the subject from enrollment into the study?

13. Does the subject have a history of noncompliance to therapies?
