    A SUPPLEMENTAL REPORT IS BEING SUBMITTED FOR DEVICE EVALUATION PRODUCT EVENT SUMMARY: THE CONTROLLER WAS RETURNED FOR EVALUATION. VARIOUS ANALYSES WERE CONDUCTED AND REVIEWED IN ORDER TO EVALUATE THE PERFORMANCE OF THE DEVICE IN RELATION TO THE REPORTED EVENT. A VISUAL INSPECTION UNDER 10X MAGNIFICATION REVEALED A HAIRLINE CRACK AROUND POWER PORT TWO. AN INTERNAL INSPECTION DID NOT REVEAL EVIDENCE OF FLUID INGRESS. THE OBSERVED HAIRLINE CRACK IS NOT RELATED TO THE REPORTED EVENT. BASED ON AN INVESTIGATION CONDUCTED UNDER CAPA PR00381374, THE ROOT CAUSE OF THE HAIRLINE CRACK WAS DETERMINED TO BE DUE TO CHEMICAL ADDITIVES APPLIED TO THE POWER PORT GASKETS DURING THE MANUFACTURING PROCESS. THE CHEMICAL ADDITIVES CONTRIBUTED TO ENVIRONMENTAL STRESS CRACKING. EVEN THOUGH THIS CAPA IS CLOSED, CONTROLLER FALLS WITHIN THE BOUNDS OF THIS CAPA. FUNCTIONAL TESTING REVEALED THAT THE NO POWER ALARM ONLY SOUNDED BRIEFLY WHEN BOTH POWER SOURCES WERE DISCONNECTED FROM THE CONTROLLER AND A CONTROLLER FAULT ALARM WAS TRIGGERED DURING BENCH TESTING, INDICATING AN ISSUE WITH THE INTERNAL BATTERY. INTERNAL INSPECTION REVEALED THAT THE INTERNAL NICKEL-METAL HYDRIDE (NIMH) BATTERY WHICH POWERS THE NO POWER ALARM WAS SWOLLEN. AFTER THE INTERNAL BATTERY WAS REPLACED, THE CONTROL LER PERFORMED AS INTENDED. LOG FILES REVEALED A CONTROLLER FAULT ALARM ON (B)(6) 2020 AT 11:04:11, INDICATING AN ISSUE WITH THE INTERNAL BATTERY. AS A RESULT, THE REPORTED EVENT WAS CONFIRMED. IN ADDITION, LOG FILES REVEALED THAT THE CONTROLLER WAS IN USE FOR MORE THAN 2 YEARS. THE MOST LIKELY ROOT CAUSE OF THE REPORTED EVENT CAN BE ATTRIBUTED TO A REDUCED CHARGE CAPACITY OF THE INTERNAL NIMH BATTERY. CAPA PR00492825 WAS OPENED TO INVESTIGATE INTERNAL BATTERY ISSUES WITH CONTROLLER 2.0. POSSIBLE CLINICAL FACTORS THAT MAY HAVE CONTRIBUTED TO THIS EVENT INCLUDE THE PATIENT¿S PRE-EXISTING HISTORY AND RELATED COMORBIDITIES, THE PROGRESSION OF THEIR UNDERLYING DISEASE, ISSUES RELATED TO THE THERAPEUTIC USE OF ANTICOAGULANT AND ANTIPLATELET MEDICATIONS AND THE PATIENT'S COMPLEX POST-OPERATIVE COURSE. THERE ARE POSSIBLE PATIENT, PHARMACOLOGICAL AND PROCEDURAL FACTORS THAT MAY HAVE CONTRIBUTED TO THIS EVENT. INVESTIGATION OF THIS EVENT IS COMPLETED, AND THE FILE WILL BE CLOSED. IF NEW INFORMATION IS RECEIVED, THE FILE WILL BE RE-OPENED, AND A SUPPLEMENTAL WILL BE SUBMITTED.
