At 10:35 a.m. on December 2, 2024, Employee #1 was performing maintenance on a sensor inside a robotic enclosure. As he entered the area, the robot was stopped by entrance sensors. While he was cleaning the sensor, a coworker reset the machine from the control panel, unaware that Employee #1 was still inside the enclosure. The robotic arm activated and struck Employee #1, reportedly lifting and placing him onto a roller platform. He sustained multiple internal and external injuries and was killed as a result of the incident.

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: IT WAS REPORTED THAT DURING A DA VINCI-ASSISTED PANCREATODUODENECTOMY PROCEDURE, AN UNSPECIFIED VESSEL WAS DAMAGED LEADING TO BLEEDING. THE PROCEDURE WAS CONVERTED TO OPEN; THE PATIENT ULTIMATELY EXPIRED. AN INTUITIVE CLINICAL TERRITORY ASSOCIATE (CTA) WHO WAS PRESENT IN THE OR DURING THE PROCEDURE REPORTED THAT WHEN THE INJURY TO THE VESSEL OCCURRED, THE SURGEON CLAMPED THE BLEEDING VESSEL WITH A ROBOTIC INSTRUMENT. THE SURGEON STATED THAT DURING THE OPEN PROCEDURE THEY COULD NOT OBTAIN FULL CONTROL OF THE BLEEDING. CHEST COMPRESSIONS WERE PERFORMED, BUT THE PATIENT EXPIRED ON THE OR TABLE. THE SURGEON STATED THAT, "THE COMPLICATION WAS NOT RELATED TO THE DEVICES BUT TO [THE] COMPLEXITY OF THE SURGERY AND DEGREE OF CANCER." COINCIDENTALLY, PRIOR TO THE VESSEL INJURY EVENT, THE CTA CALLED INTUITIVE TECHNICAL SUPPORT ENGINEERING (TSE) TO REPORT THAT WHEN SWAPPING INSTRUMENTS, THE UNIVERSAL SURGICAL MANIPULATOR 3 (USM ARM3) WOULD JUMP MORE THAN NORMAL AND WOULD CANCEL GUIDED TOOL CHANGE (GTC). THE (TSE) REVIEWED THE SYSTEM LOGS AND FOUND NO RELATED ERRORS AT THE TIME OF THE CALL. THE CTA ALSO REPORTED A SYNCHROSEAL INSTRUMENT IN USE ON USM ARM3 COULD ONLY ROTATE TO THE RIGHT. THE TSE

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: IT WAS REPORTED THAT APPROXIMATELY 25-30 MINUTES INTO A DA VINCI-ASSISTED SIMPLE PROSTATECTOMY PROCEDURE, THE PATIENT EXPERIENCED HEMODYNAMIC INSTABILITY WITH A DROP IN BLOOD PRESSURE AND HYPOXIA. THE CARDIAC ANESTHESIOLOGIST PERFORMED A TRANSESOPHAGEAL ECHOCARDIOGRAM AND A CO2 GAS EMBOLUS WAS OBSERVED IN THE RIGHT VENTRICLE. THE SURGICAL FELLOW REPORTED THAT THE PATIENT WAS IN A TRENDELENBURG POSITION OF APPROXIMATELY 10 DEGREES AND THE 3RD PARTY INSUFFLATION DEVICE PRESSURE WAS SET TO 12 MMHG. THE PROCEDURE WAS ABORTED; THEY WERE AT THE PROSTATE ENUCLEATION STEP WITH APPROXIMATELY ANOTHER 15-20 MINUTES REMAINING IN THE PROCEDURE. THE PATIENT DECOMPENSATED A SECOND TIME IN THE INTENSIVE CARE UNIT AND EXPIRED ABOUT 4-5 HOURS POST-OPERATIVELY. THE PATIENT HAD A HISTORY OF CARDIAC COMORBIDITIES. THE REPORTED CAUSE OF DEATH WAS CO2 EMBOLUS AND MYOCARDIAL INFARCTION. THE FELLOW STATED THAT THE EVENT WAS NOT CAUSED BY ANY DA VINCI PRODUCT; IT WAS A COMBINATION OF THE PRE-EXISTING CARDIAC CONDITION AND ABSORPTION OF CO2 GAS.

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: IT WAS REPORTED THAT AFTER A DA VINCI-ASSISTED RADICAL PROSTATECTOMY PROCEDURE, THE PATIENT DIED OF A PULMONARY EMBOLISM ON AN UNSPECIFIED DATE. THE PROCEDURE WAS COMPLETED WITHOUT COMPLICATIONS AND THE PATIENT HAD A FAST INITIAL POST-OPERATIVE RECOVERY. THE SURGEON AND THE HOSPITAL TEAM DO NOT THINK THIS IS DIRECTLY RELATED TO THE DA VINCI SINGLE PORT (SP) SYSTEM USED. ADDITIONAL INFORMATION WAS REQUESTED FROM THE SURGEON AND A RESPONSE IS PENDING.

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: A LITERATURE ARTICLE THAT DESCRIBED A COHORT STUDY OF 2225 PATIENTS THAT UNDERWENT ROBOT-ASSISTED SURGERY (RAS) IN GYNECOLOGICAL ONCOLOGY FROM JANUARY 2015 TO DECEMBER 2022. THE AIM OF THE STUDY WAS TO PROVIDE A COMPREHENSIVE DESCRIPTION OF PERIOPERATIVE MORBIDITY ASSOCIATED WITH ROBOT-ASSISTED SURGERY (RAS) IN GYNECOLOGICAL ONCOLOGY TO ENHANCE PREOPERATIVE COUNSELING AND SUPPORT SHARED DECISION-MAKING. A GYNECOLOGICAL ONCOLOGIST PERFORMED THE SURGERY IN 98% OF THE CASES, AND 64% OF THESE SURGEONS WERE ALREADY EXPERIENCED IN RAS (>50 ROBOTIC PROCEDURES). THE DA VINCI SI SYSTEM WAS USED IN 524 CASES AND THE DA VINCI XI SYSTEM IN 1701 CASES. AMONG THE 2225 PATIENTS, THE ARTICLE NOTED THAT ONE PATIENT DIED DUE TO CARDIOGENIC SHOCK 2 WEEKS AFTER UNCOMPLICATED RAS, THE CAUSE OF DEATH WAS FOUND TO BE MAJOR THROMBOEMBOLIC EVENT (TEE). THERE WERE NO DA VINCI DEVICE MALFUNCTIONS REPORTED, NOR DID THE AUTHORS ALLEGE THAT ISI PRODUCTS CAUSED OR CONTRIBUTED TO ANY ADVERSE EVENTS. THE STUDY CONCLUDED THAT RAS IN A HIGH-VOLUME GYNECOLOGICAL ONCOLOGY SETTING RESULTED IN LOW RATES OF MAJOR PERIOPERATIVE MORBIDITY AND CONVERSION TO LAPAROTOMY. THE FINDINGS SUPPORT THE USE OF RAS FOR SUITABLE PATIEN

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: A LITERATURE ARTICLE DESCRIBED A RETROSPECTIVE ANALYSIS BETWEEN 2011-2022 OF 184 PATIENTS THAT UNDERWENT DA VINCI ASSISTED TORS SURGERY WITH NECK DISSECTION IN ONE SINGLE INSTITUTION, PERFORMED BY TWO TRAINED SURGEONS. THE STUDY WAS CONDUCTED TO EVALUATE THE ONCOLOGICAL OUTCOMES OF POST-TRANSORAL ROBOTIC SURGERY (TORS) FOR HPV-ASSOCIATED OROPHARYNGEAL SQUAMOUS CELL CARCINOMA. THE 3-YEAR AND 5-YEAR DISEASE-SPECIFIC SURVIVAL WERE 98.6% (95% CI 96.7¿100%) AND 94.4% (95% CI 89.9¿99.0%), RESPECTIVELY. THREE PATIENTS DIED FROM CAUSES UNRELATED TO DISEASE RECURRENCE. ONE PATIENT (0.5%) HAD AN EARLY POSTOPERATIVE HEMORRHAGE, DEFINED BY BLEEDING OCCURRING LESS THAN 24 HOURS FOLLOWING SURGERY, RESULTING IN DEATH FOUR DAYS LATER. ONE PATIENT DIED FROM CARDIOPULMONARY ARREST; ANOTHER PATIENT DIED FROM A SECOND TUMOR METASTASIS. THERE WERE NO DA VINCI DEVICE ISSUES REPORTED IN THE ARTICLE. MULTIPLE REQUESTS FOR ADDITIONAL INFORMATION FROM THE DESIGNATED AUTHOR WERE MADE, BUT NO RESPONSE HAS BEEN RECEIVED.

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: REVIEW OF AN ARTICLE WAS COMPLETED OF A RANDOMIZED CONTROLLED TRIAL BASED ON DA VINCI-ASSISTED ROBOTIC PANCREATICODUODENECTOMY (RPD) WHERE THE AUTHORS COMPARED THE SHORT-TERM POSTOPERATIVE OUTCOMES OF RPD WITH THOSE OF OPEN PANCREATICODUODENECTOMY (OPD). THE TRIAL, CONDUCTED BETWEEN MARCH 5 AND DECEMBER 20, 2022, INCLUDED 164 PATIENTS RANDOMLY ASSIGNED TO EITHER THE RPD OR OPD GROUP. IN THE RPD GROUP, THERE WAS ONE IN-HOSPITAL DEATH (1%) WITHIN 90 DAYS AFTER THE OPERATION. SPECIFICALLY, ONE (1%) OF 81 PATIENTS IN THE RPD GROUP DEVELOPED POSTOPERATIVE PANCREATIC FISTULA RELATED HEMORRHAGE ON POSTOPERATIVE DAY 9, UNDERWENT TRANS-ARTERIAL EMBOLIZATION AND A SUBSEQUENT REOPERATION, BUT DIED OF SEPTIC SHOCK ON DAY 30. THERE WERE NO DA VINCI DEVICE MALFUNCTIONS REPORTED. THE OPD SUBSET ALSO HAD ONE PATIENT DEATH DUE TO A PULMONARY EMBOLISM ON POSTOPERATIVE 5. THE ARTICLE STATES THAT WHILE RPD SHOWED BENEFITS IN REDUCING HOSPITAL STAY, THE OVERALL CLINICAL BENEFIT REMAINS UNCLEAR, ESPECIALLY CONSIDERING THE EXTRA COSTS AND PATIENT PERCEPTIONS OF QUALITY OF LIFE AND RECOVERY AFTER DISCHARGE.

At 10:00 p.m. on February 22, 2024, an employee working as a machine operator for a landscape architectural service had been monitoring a production line (Line 1). The employee started his shift at 3:00 p.m. He was operating the conveyer that carries pallets loaded with landscape materials such as bags of mulch, decorative rocks, and soil. The employee works with a robotic arm that picks up landscape materials from the conveyor and places them on a pallet. When the pallet is full, it moves down the conveyer. A coworker who operates a forklift noticed a pallet was crooked and mentioned it to the employee before leaving the area to do his assigned work. After returning to the area, the coworker saw the employee inside the cage with the door closed. The employer stated that the employee must have entered across the conveyer causing the robot to pick the employee up thinking he was a pallet. The employee was caught within the cage under a robotic arm and died from crushing injuries to his chest.

da Vinci Surgical System — Death report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: IT WAS REPORTED THAT THE PATIENT UNDERWENT AN UNEVENTFUL DA VINCI ASSISTED LOW ANTERIOR RESECTION FOR COLORECTAL CANCER. THE SURGEON STATED THAT THE ANASTOMOSIS WAS END-TO-END, CREATED WITH AN ETHICON ILS 29 CIRCULAR STAPLER. TESTING OF THE ANASTOMOSIS WAS PERFORMED DURING THE OPERATION AND NO LEAKAGE WAS FOUND. THE PATIENT EXPERIENCED COMPLICATIONS POSTOPERATIVELY AND EXPIRED APPROXIMATELY 69 DAYS POST-PROCEDURE. THERE WAS NO REPORT OF ANY ISSUES WITH THE DAVINCI PRODUCTS. ON POST-OPERATIVE DAY 4 (POD) THE PATIENT'S BLOOD PRESSURE SIGNIFICANTLY DROPPED AND CT SCANS SHOWED PNEUMOPERITONEUM. ANASTOMOSIS LEAKAGE, PERITONITIS, AND SEPSIS WERE SUSPECTED AND AN EMERGENT RE-OPERATION WAS PERFORMED. THE PATIENT REQUIRED POST-OPERATIVE CIRCULATORY AND OXYGEN SUPPORT VIA VENO-ARTERIAL AND VENO-VENO EXTRACORPOREAL MEMBRANE OXYGENATION (ECMO) AND VASOPRESSORS DUE TO RESPIRATORY FAILURE AND SEPTIC SHOCK. ON POD 7 THE CIRCULATORY SUPPORT WAS CHANGED TO VENO-VENOUS ECMO ONLY, WHICH WAS REMOVED FIVE DAYS LATER AFTER THE PATIENT WAS HEMODYNAMICALLY STABLE. THE PATIENT WAS TREATED WITH ANTIBIOTICS FOR ILEOSTOMY AND WOUND INFECTIONS. THE PATIENT'S HAND BECAME CYANOTIC FROM THE ECMO TREATMENT REQUIRI
