The court granted defendant-doctor's motion for a directed verdict, and dismissed the complaint, in this action where plaintiff's expert did not specifically opine as to whether defendant departed from a specific standard of accepted medical practice. The conduct at issue, which involved the implantation of a technologically challenging device, is not within the knowledge of a lay jury. Neither, in the absence of expert testimony, could the jury discern whether this was a known risk or negligence.
