ANAHEIM, Calif., Sept. 24 /PRNewswire/ -- ConvaTec, a world-leading developer and marketer of innovative medical technologies for community and hospital care, today announced new in vitro study results. The Engenex® Negative Pressure Wound Therapy (NPWT) system's Bio-Dome™ wound interface showed superior tensile strength and lower simulated bioadhesion when compared with GranuFoam™ (polyurethane foam).(1) This study was conducted by employees of ConvaTec's Global Development Center and was presented at The Annual Fall Symposium on Advanced Wound Care in Anaheim, California.

In addition to the superior tensile strength and lower simulated bioadhesion, the laboratory tests also showed that the Bio-Dome™ wound interface provided broader contours of microstrain when compared to GranuFoam™. The Bio-Dome™ wound interface also effectively transmitted sufficient levels of fluid to the canister from simulated highly exuding wounds.(1)

To better understand the physical performance attributes of wound interfaces, a range of in vitro physical testing and analytic studies using different levels of applied negative pressure were performed.

The analytic studies included finite element analysis (FEA) to predict strain forces applied to the wound bed; fluid handling testing to simulate exudate management capabilities; tensile strength of interface dressings to show their robustness during handling; and simulated bioadhesion testing.
