Covalon Technologies Inc. Receives Health Canada Approval

MISSISSAUGA, ONTARIO--(MARKET WIRE)--May 20, 2008 -- Covalon Technologies Ltd. (CDNX:COV.V - News) is pleased to announce that it has received approval from the Therapeutic Product Directorate at Health Canada to begin marketing the Corporation's proprietary products:

- BIOSTEP(TM) Collagen Matrix Dressing, and

- BIOSTEP(TM) Ag Collagen Matrix Dressing with Silver.

The products are advanced wound care dressings that create a moist wound healing environment, deactivate harmful wound proteases and promote tissue growth in chronic wounds, which affect an increasingly large number of patients and have a serious impact on their quality of life.

The products will be marketed by Smith & Nephew Inc. under the terms of an exclusive worldwide sales, marketing and distribution agreement announced last year.

"We are extremely pleased to receive license approvals for these products" said Dr. Frank DiCosmo, President and CEO of Covalon. "Clinicians participating at a clinical in-market study indicated that these new collagen dressings facilitate granulation and epidermal migration as the majority of patients experienced a reduction in wound areas and an increase in the percentage of epithelial tissue over time. In the case of BIOSTEP(TM) Ag, participating clinicians indicated that absorption of silver by the cells appears to improve the local microenvironment to promote the healing process". BIOSTEP(TM) and BIOSTEP(TM)Ag are manufactured in the U.S.A. by Covalon Technologies Ltd., exclusively for Smith & Nephew; (TM)Trademark of Smith & Nephew.

"Covalon's talented research and development staff is actively working on broadening our proprietary collagen-based platform in order to address other exciting medical applications in the near future", said Dr. DiCosmo.
