The 3D configuration is designed to optimize compression not only underneath each staple but also across staples and multiple staple lines, including both stapled and unstapled regions of the tissue.

Reducing preparation time in the OR prior to actual surgery can improve operating room efficiency and utilization, but only if patient safety can be maintained. With this goal, this study evaluated a novel skin preparation technique using a device named ULTRAPREP™, a sterile, medical-grade plastic bag that is applied to the upper or lower extremity in the pre-operative holding area which allows for skin disinfection outside the OR (referred to as \"disinfection bag\"). The study compared preparation times required in the OR and antiseptic efficiency (through Colony Forming Units (CFU) counts) for traditional methods versus using the disinfection bag on a total of 115 patients undergoing podiatric or orthopedic surgeries (upper and lower extremities) in one hospital. The disinfection bag reduced skin preparation time in the OR from 16.8±3.5min to 10.9±2.7min, which was a 35.2% reduction, and was statistically significant (p<0.01). Skin antisepsis met safety standards of <15 CFUs for all cases regardless of preparation type at 48h and 72h. There was no statistical difference in CFU levels between the traditional and disinfection bag methods at 48h or 72h (p>0.11).
