A Dual-center Study Evaluating Clinical Acceptance of a NPWT Wound Care System

The primary objective is to evaluate whether clinical opinion of product performance results in expected wound response and outcomes when using the Medela Invia Motion Endure NPWT system during 4-week study duration.

* Goal of therapy will be defined by the physician according to initial assessment:

Endpoints (dependent on goal of therapy):

* Decrease in wound volume
* Decrease in size of the tunneling area
* Decrease in size of undermining
* Decrease in amount of slough
* Increase in granulation tissue
* Decrease in edema/periwound swelling
* The wound bed is progressing acceptably towards a transition to another treatment modality such as Moist Wound Healing (MWH), surgical closure, or a flap or graft.

**Study endpoint will be determined by physician at the time of enrollment, when the goal of therapy is documented**

• Invia Motion Endure NPWT system (Device): lightweight portable single patient use pump, that provides continous or intermittent operation and multiple negative pressure selection options

Primary outcomes

• Goal of therapy: Change in wound volume [Up to 4 week study duration]: Wound measurements will be performed each week and length, width and depth of the wound measured during treatment until goal of the therapy is reached
• Goal of therapy: Change in size of the tunneling area [Up to 4 week study duration]: Wound measurements will be performed each week and the tunneling of the wound measured during treatment until goal of the therapy is reached
• Goal of therapy: Change in size of undermining [Up to 4 week study duration]: Wound measurements will be performed each week and the undermining of the wound measured during treatment until goal of the therapy is reached
• Goal of therapy: Change in amount of slough [Up to 4 week study duration]: Wound measurements will be performed each week and the amount of slough measured during treatment until goal of the therapy is reached
• Goal of therapy: Change in granulation tissue [Up to 4 week study duration]: Wound measurements will be performed each week and the amount of granulation tissue measured during treatment until goal of the therapy is reached
• Goal of therapy: Change in edema/periwound swelling [Up to 4 week study duration]: Wound measurements will be performed each week and the presence of edema determined during treatment until goal of the therapy is reached
• Goal of therapy: The wound bed is progressing acceptably towards a transition to another treatment modality such as Moist Wound Healing (MWH), surgical closure, or a flap or graft [Up to 4 week study duration]: Wound measurements will be performed each week and the wound bed visually determined during treatment until goal of the therapy is reached

Secondary outcomes

• Evaluate the ease of use from clinicians [Up to 4 week study duration]: A weekly staff satisfaction survey will be obtained from the wound clinic staff members to determine ease of use on a scale from higher to worse score with four values (more satisfied, satisfied, neutral, less satisfied)
• Evaluate overall satisfaction from clinicians [Up to 4 week study duration]: A weekly staff satisfaction survey will be obtained from the wound clinic staff members to determine overall satisfaction with the device on a scale from higher to worse score with four values (more satisfied, satisfied, neutral, less satisfied)

Other outcomes

• Determine performance satisfaction of dressing components on periwound [Up to 4 week study duration]: A weekly staff satisfaction survey on the ability to maintain dressing seal will be obtained from the wound clinic staff members to determine performance satisfaction of dressing components on periwound on a scale from higher to worse score with four values (more satisfied, satisfied, neutral, less satisfied)
