Kinetic Concepts, Inc. (KCI)
1) How many different NPWT products does your company currently produce?
KCI manufactures and sells five different NPWT products: ActiV.A.C.® Therapy System, InfoV.A.C.® Therapy System, V.A.C. Instill® Wound Therapy, V.A.C. Freedom® Therapy System and, most recently, the V.A.C.Via™ Therapy System. The V.A.C.Via™ Therapy System is KCI’s first for-sale, single-use NPWT unit. V.A.C.® Therapy is the leading NPWT brand and the most studied among NPWT products. Other KCI devices within its Negative Pressure Technology (“NPT”) portfolio include the Prevena™ Incision Management System and the ABThera™ Open Abdomen Negative Pressure Therapy System.

2) Please name your most popular NPWT product?
The ActiV.A.C® Therapy System is currently our most popular NPWT product.
3) What is the suction pressure of your machine or the range of pressure that the machine achieves?
The pressure provided by the ActiV.A.C.® Therapy System is preset to -125 mmHg. This default setting is within the V.A.C.® Therapy Clinical Guidelines recommended range for most wounds. The user selectable negative pressure range is between 25-200 mmHG, with the pressure setting selection being left to physician discretion.
4) Is the pressure pre-set?
The pressure provided by the ActiV.A.C® Therapy System is preset to -125 mmHg and continuous therapy.
5) Can it be changed?
Yes, the level of therapeutic negative pressure for all KCI NPWT units can be changed by using the control panel on the therapy unit. Settings are adjustable based on individual patient clinical needs and circumstances.
6) Is there an intermittent feature?
Yes, all KCI NPWT units, including the ActiV.A.C.® Therapy System, offer both continuous and intermittent negative pressure therapy applications.
7) Is there a cut off which stops suction if the canister is full?
All of our NPWT units contain electronic sensors that stop the pump when the canister is full.
8) Is there a one-way valve to prevent fluid from coming back through the tubing towards the patient?
No, there are no one-way valves in the system; however, there are other safety features, which mitigate retrograde flow toward the patient. KCI’s proprietary SensaT.R.A.C.™ Tubing used in conjunction with V.A.C.® Therapy has clamps at both the patient and canister side to prevent this fluid transfer. Additionally, canisters are available with a gel pack that helps to solidify wound exudate.
9) How long does the battery last?
The ActiV.A.C.® Therapy System’s battery lasts for 14 hours on average when fully charged.
10) How much does the machine weigh?
The ActiV.A.C.® Therapy System is fully portable and only weighs 2.4 lbs. when the 300ml canister is empty. The recently launched V.A.C.Via™ Therapy System is specifically designed for mobility and weighs only 0.7 lbs with a 250ml canister.
11) What is the interface with the wound?
KCI offers a variety of wound dressings:
•V.A.C.® GranuFoam™ Dressing
•V.A.C. GranuFoam Silver® Dressing
•V.A.C.® WhiteFoam Dressing
•V.A.C.® Simplace™ Dressing
•V.A.C.® GranuFoam™ Bridge Dressing
Additional V.A.C.® GranuFoam™ specialty dressings are available.
The V.A.C.® GranuFoam™ Dressing is placed directly at the wound site to facilitate negative pressure application. The unique pore structure of V.A.C.® GranuFoam™ Dressings help promote healing and tissue granulation. Each tiny pore is intended to deliver mechanisms critical to wound healing. The V.A.C.® GranuFoam™ Dressing adapts to the contours of deep and irregularly shaped wounds, helps provide uniform distribution of negative pressure at the wound site, helps facilitate exudate and infectious material removal through a hydrophobic pore structure, compresses to less than half its size under negative pressure to help draw wound edges together and induces macrostrain and microstrain.
12) How often do you recommend changing the dressing?
Current device labeling recommends that following: Wounds being treated with V.A.C.® Therapy should be monitored on a regular basis. In a monitored, non-infected wound, V.A.C.® Dressings should be changed every 48 to 72 hours, but no less than three times per week, with frequency adjusted by the clinician as appropriate.
Infected wounds must be monitored often and very closely. For these wounds, the dressing change intervals should be based on a continuing evaluation of wound condition and the patient’s clinical presentation, rather than a fixed schedule. Dressings may need to be changed more often than 48 to72 hours.
13) Can you “y” wounds together and if so how many?
Yes, the ActiV.A.C.® Therapy System can be used to “Y” two wounds together if they are of the same etiology. By applying a Y-connector to the canister tubing, one V.A.C.® Therapy unit may be used to simultaneously treat multiple wounds on the same patient.
14) How do you handle undermining?
KCI V.A.C.® Therapy WhiteFoam Dressing may be placed in undermined areas, with good foam to tissue contact. When using the V.A.C.® Therapy WhiteFoam Dressing, the minimum pressure setting is -125 mmHg.
