Lead Sponsor:
KCI USA, Inc
Conditions:
Diabetic Amputation Foot Wound
Eligibility:
All Genders
18+ years
Phase:
NA
Brief Summary
The objective of this study is to thoroughly examine the role of V.A.C. NPWT in the further salvage of the diabetic foot once it has undergone partial amputation. To determine this, measures of healin...
Detailed Description
Primary objective is to compare time required to achieve wound bed preparation between Subjects randomized to receive V.A.C. NPWT or MWT. Subjects with ALL the following are eligible for clinical tria...

- Presence of necrotic tissue with eschar or slough that cannot be debrided
- Persistent periwound maceration of \>96 hours
- Inadequate wound hemostasis that might impair wound healing

- History of clinically significant chronic anemia as evidenced by a hemoglobin concentration of \<10.0 g/dL within ≤30 days of screening
- Severe venous insufficiency (with or without the presence of venous leg ulcers) that may impair wound healing
