Event Description
|
Note: this report pertains to one of two alliance ii inflation syringes used during the same procedure.It was reported to boston scientific corporation that two alliance ii inflation syringes were used in the esophagus during an upper gastrointestinal balloon dilation procedure performed on (b)(6) 2024.During the procedure, while inflating the cre dilation balloon at the target site, when pressure of more than 3 atm was applied the balloon dilation did not proceed.After repeated attempts, the balloon finally dilated when pressure was applied more gently than usual.The customer reported that there was an inconsistency between the dilation pressure and balloon size.The same problem occurred with the second alliance ii inflation syringe.The procedure was completed with another alliance ii inflation syringe.There were no patient complications reported as a result of this event.No further information has been obtained despite good faith efforts.The reported event may suggest that the alliance ii inflation syringe pressure gauge was reading inaccurately.
