The IMP support team is ready and eager to keep your De Mayo Knee Positioners® performing optimally.

This service is guaranteed to put a smile on your Surgeon's face!

With current events upon us, now is a great time to send in your IMP® positioners for a performance tuneup. In addition to repairs that can return your product to optimal performance, we'll also return your De Mayo Surgical Positioner with these upgrades:

Laser Serialization

Laser-etched numbers assure that the correct components (base, carriage, and boot) stay together. Extends life, reduces wear, and simplifies assembly.

New Knurled Thumb Screw & Spring Assembly

Allows easy tool-less assembly of the spring handle and permits proper carriage tension while placing the handle in a preferred position

New Locking Knob

Prevents carriage sliding in Flexion/Extension, allowing the boot to be removed for ROM testing and placed back in the same flexion position.

Downloads & Documentation


  • “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. 

    - Anonymous -Central Sterile Services (CSS) Administrator
  • "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."

    - Brenda Conbeer -OR Inventory Coordinator
