Wound closure matrix
PMI developed SUPRA SDRM®CW as a proven wound closure matrix optimized for the treatment of difficult-to-heal wounds. The product also contains SUPRA EPT™, the technology developed for SUPRATHEL®.
Pore size distribution
SUPRA SDRM®CW combines the benefits of SUPRATHEL®‘s microporous structure with additional larger pores which allow blood vessel ingrowth for the treatment of chronic and difficult-to-heal wounds.
SUPRA SDRM®CW has the ideal pore size distribution for rapid wound healing:
• The small pores (3-12 µm) support initial cell migration.1
• The large pores (50 – 600 μm) and high porosity lead to cell attachment and vascularization.2,3
Cell Migration
Ideal pore size distribution of SUPRA SDRM®CW for wound healing in µm. Pores greater than 50 µm promote vascularisation, while pores between 3 and 12 µm promote cell migration.1-3

Composition
SUPRA SDRM®CW is a purely synthetic product and therefore does not bear any of the potential residual risks, that can occur with biological products of human or animal origin.PMI’s SUPRA EPT™ incorporates a unique and proprietary copolymer which leaves only CO2 and H2O as degradation products
SUPRA SDRM®CW contains a bimodal foam membrane structure, that, based on the literature, has the optimal combination of small and large pores – smaller pores promote cell migration while the larger, interconnected pores support vascularisation. This unique bimodal pore structure is a proprietary feature of PMI.

Clinically proven
In a recent prospective, randomised trial, SUPRA SDRM®CW led to faster healing rates compared to collagen dressings.(4)
• SUPRA SDRM®CW reduced the required time for wound healing of diabetic foot ulcers by 44% compared to
collagen-based dressings.
• Moreover, 90% of wounds treated were closed after 12 weeks compared to only 30% in the collagen group.
