CyberKnife — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: A PT ENROLLED IN A NON ACCURACY SPONSORED STUDY, UNDER (B)(4) OVERSIGHT, EXPERIENCED COMPLICATIONS. THE PT EXPERIENCED PELVIC PAIN AND PROSTATE SLOUGHING AND UNDERWENT A CYSTOPROSTATECTOMY. THE PHYSICIAN INDICATED THERE WAS NO MALFUNCTION OF THE DEVICE.

CyberKnife — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: COMPLICATIONS WERE DESCRIBED IN A ORAL PRESENTATION (B)(6). ACCURAY PREVIOUSLY CONTACTED THE PHYSICIAN AND CONFIRMED THAT THE REPORTED COMPLICATIONS WERE NOT DUE TO A MALFUNCTION OF THE CYBERKNIFE SYS. THE PTS HAD RECEIVED PRIOR RADIOTHERAPY AND WERE UNDERGOING RE-IRRADIATION BY THE CYBERKNIFE SYS IN AN ATTEMPT TO CONTROL RECURRENT DISEASE. DUE TO THE NATURE AND EXTENT OF DISEASE, CYBERKNIFE TREATMENT WAS THE ONLY TREATMENT OPTION FOR THE PTS IN THE STUDY.

CyberKnife — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: ON 04/11/2013 WHILE READING A DRAFT RESEARCH PAPER ENTITLED "STEREOTACTIC BODY RADIATION THERAPY FOR HEPATOCELLULAR CARCINOMA; PROGNOSTIC FACTORS OF LOCAL CONTROL, OVERALL SURVIVAL, AND TOXICITY"; AN ACCURAY EMPLOYEE BECAME AWARE OF AN ADVERSE EVENT. THIS STUDY IS PARTIALLY FUNDED BY ACCURAY. THE PAPER REPORTS THAT THREE MONTHS AFTER A CYBERKNIFE TREATMENT FOR A TUMOR IN THE LIVER, ONE PATIENT EXPERIENCED A GRADE 4 GASTRIC ULCER, RESULTING IN A DIGESTIVE HEMORRHAGE, WHICH WAS TREATED. THE PAPER REPORTS FOLLOWING THE ADVERSE OUTCOME "TREATMENT PLANS WERE REVIEWED AND STRICT CONSTRAINTS WERE DEFINED FOR SUBSEQUENT TREATMENTS." THE PRINCIPLE INVESTIGATOR CONFIRMED THE CYBERKNIFE DID NOT MALFUNCTION.
