Abstract: Medical device failure and misuse have the potential to cause serious injury and death. Given the intricate nature of the instruments utilized specifically in minimally invasive surgery (MIS), users and manufacturers of surgical devices share a responsibility in preventing user error and device failure. A novel approach is presented for the evaluation of minimally invasive device failures, which involves assessing the severity of adverse event outcomes associated with the failure modes and investigating aspects of the devices' design that may contribute to failure.  The goals of this research were to 1) characterize the design attributes, failure modes, and adverse events associated with minimally invasive surgical devices and 2) describe the relationship between minimally invasive surgical device design complexity and the severity of adverse events.  The types of failure modes, phases of operation in which failure occurs, severity of adverse event outcomes, and design complexity associated with four minimally invasive surgical devices were determined.

Speaker: Marie Riggs, completed her PhD in mechanical engineering at the University of Louisville.  Her research focuses on the intersection of design theory and medical devices used for minimally invasive surgeries to provide both users and designers of surgical devices with valuable insight into potential complications, and a means to implement user and design countermeasures against undesired outcomes in the surgical setting.

Dr. Riggs completed her doctoral work while simultaneously participating in the Industrial Hemp Pilot Program in Kentucky as founder and owner of Botanical Processing, LLC.  The startup specializes in supercritical CO2 extraction and refinement of high quality oils from botanicals for product formulation and wholesale.
