ACell, Inc. announced a distribution agreement with Southmedic, Incorporated. Under the agreement, ACell will be the exclusive US distributor of Southmedic's Dynamic Tissue Systems (DTS) product line. Additionally, this agreement establishes Southmedic as the exclusive Canadian distributor of ACell's current line of medical devices. The DTS product portfolio includes six devices designed to facilitate faster wound closure in a variety of clinical situations. The devices provide dynamic appositional forces, or cyclic stretching, which relax the natural retraction of open wounds through mechanical stretch. Chronic cyclic stretching leads to constructive remodeling, including tissue generation and adaptation.
