Consulting Services:
Selected Consulting Examples:
  • Several of Expert's investigations involved surgical staplers, which are used instead of sutures to speed and reduce the complexity of certain surgeries. By examination of the staplers, recovered staples, and excised tissue, he was able to demonstrate that the stapler that these were cases of device misuse and not the fault of the device.
  • By examination of the location of the air intake for a medical air system, Expert showed that intermittant contaminants were entrained with the intake air and led to poisoning deaths of neonates.
  • A surgical fire case involved an emergency procedure in which an alcohol-based skin prep was inappropriately used. Expert demonstrated how the fire was started and spread causing the pattern of burns to the patient.
  • Several of Expert's cases involved catheters. In one case, simple observation of the failure surface of the catheter showed that it was cut with scissors. It was possible that this was a user error or a purposeful act.
  • A purported case of frostbite was attributed to a cooling pad that used ice water. Eng. demonstrated that the device could not cause frostbite and that the injuries sustained were most likely caused by long exposure to wet and cold contrary to the device's and doctor's instuctions for use.
