  • “It’s very helpful in the OR, for example, we used it last weekend on a sub troch fracture in the lateral position and it helped us position.” 

    - Dr. James Cameron -MD
  • “I like the SteriBump because it’s lint-free, safer for patient positioning because it’s more secure and easier for the doctor to use than wrapping towels.”

    - Caitlyn Pourcho -RN, OR Circulator
  • “From establishing the position and securing the patient to performing procedures and testing range of motion, we created a system that’s faster and easier while also giving doctors completely unrestricted access to the surgical field.” 

    - Ed De Mayo M.D. -Device Inventor
  • Our hospital purchased SteriBump® to replace our handmade ‘bundles’ for many of the same reasons that hospitals moved away from re-sterilizing cloth OR table drapes some years ago.

  • "The best reason I have for using the SteriBump is that it is sterile every time. The sterility is validated. We were using rolled blankets that were sterilized before this that were sterilized in Sterile Processing. It's one less item they have to deal with and try to keep up with."
