Biostep Collagen Matrix Dressing

BIOSTEP◊ is a unique collagen matrix dressing that allows you to overcome barriers to wound closure while maintaining an optimal moist wound environment. It targets and deactivates excess MMPs and has a 6-day wear time for prolonged control of the wound environment. The highly conformable dressing is easy to apply, and its gelling actions provide a cooling, soothing effect for enhanced patient comfort.

BIOSTEP◊ Ag combines the anti-MMP activity and functionality of BIOSTEP◊ with the antibacterial activity of silver to help maintain bacterial balance for contaminated and colonized wounds.

Features & Benefits

Unique Dual-Action MMP Targeting & Deactivation
MMP Targeting: contains both type 1 and denatured (gelatin) porcine-derived collagen. This novel collagen matrix attracts and serves as sacrificial substrates for a broad array of MMPs which are found in excess within, and contribute to the chronicity of, chronic wounds.

MMP Deactivation: contains EDTA (a proven MMP modulating agent) which permanently deactivates excess MMPs, providing prolonged, targeted MMP control without altering the activity of essential growth factors. This contributes to a longer wear time.

Patient Friendly
CMC within dressing gels on contact with moisture providing improved patient comfort by creating a soothing, cooling effect upon application. Up to a 6-day wear time provides for fewer dressing changes and prolonged control of wound environment.

Easy to Use
CMC within dressing adds structure for easy application when moist. Highly conformable to ensure close contact with wound bed.

Moisture Manager
Alginate absorbs a high level of exudate away from the wound bed to the secondary dressing maintaining an optimal moisture balance for wound closure.
