Repligen, in partnership with Intuitive Surgical Inc, has developed a cost-effective, sterile, single-use stowed instrument arm drape. The drape was designed to cover the 4th da Vinci^® Xi™ robotic instrument arm when not in use in order to maintain the sterile surgical field. The drape is made of a clear polyethylene with anti-static properties that make clinician application easy and turnaround between procedures fast.
