Investigation ¿ evaluation.Beijing mednovo med.Tech.Co.Notified cook on 23dec2019 of an incident involving a coda balloon catheter (coda-2-10.0-35-120-32) from lot number 9761188.It was reported that a 56-year-old female with a history of lumbar malignancy presented with an abdominal aortic aneurysm (aaa) and had an endovascular aneurysm repair (evar) procedure performed.It was reported that the balloon used in the procedure was leaking.Per further communication with the user facility, it was clarified that the patient has recovered well and that the malfunctioning device was replaced with another to complete the procedure.A review of the documentation, complaint history, device history record, drawing, instructions for use (ifu), and quality control, as well as a visual inspection of the returned device were conducted during the investigation.The used complaint device was returned for evaluation.The device examination found there was no visible biomatter on the device.No damage to the catheter or balloon was observed.A leak test was performed; the balloon was inflated with water and no leakage was detected.Additionally, a document based investigation evaluation was performed.A review of the device master record found that proper procedures are in place to identify and prevent this failure mode prior to device distribution.A review of the design history file (dhf) showed that this device is both safe and effective for its intended use.A review of the device history record found no nonconformances or additional complaints associated with this device lot.There is no evidence to suggest there is any nonconforming product in house or out in the field.Additionally, a review of the product labeling for the device was completed.The instructions for use state the following instructions related to the reported failure mode: "balloon preparation note: balloon and balloon lumen of the coda and the coda lp balloon catheters contain air.The air must be removed from balloon and balloon catheter prior to insertion using standard technique.1.Remove protective balloon sleeve.2.Prepare balloon lumen with standard 3:1 saline and contrast mixture as follows: a.Attach syringe, with appropriate amount of 3:1 saline and contrast mixture, to stopcock on balloon lumen b.Purge all air from balloon in standard fashion.C.Completely deflate balloon and close stopcock.3.To increase ease of insertion, balloon may be lubricated with a thin layer of sterile, biocompatible lubricant.Balloon introduction and inflation 1.Flush the distal lumen using heparinized saline solution.2.Advance the balloon catheter over a pre-positioned.035 inch wire guide, utilizing a minimum 14.0 french introducer sheath for the 10.0 french coda balloon catheter or a minimum 12.0 french introducer sheath of the 9.0 french coda lp balloon catheter.Note: if resistance is met while advancing the wire guide or balloon catheter, determine the cause and proceed with caution.Caution: prior to introduction, determine the amount of standard 3:1 saline and contrast mixture needed to inflate the balloon to the desired inflation diameter.Refer to the balloon inflation parameters chart in fig.1.Over-inflation of the balloon may result in damage to vessel wall and/or vessel rupture.3.Under fluoroscopy, advance the balloon to the desired position using radiopaque markers.Caution: if the coda or coda lp balloon catheter is being utilized to expand a vascular prosthesis, use the radiopaque markers to ensure that the entire balloon is positioned within the prosthesis.4.Inflate balloon with standard 3:1 saline and contrast mixture using a 20 cc or larger syringe.Adhere to recommended balloon inflation volumes.5.If balloon pressure is lost and/or balloon rupture occurs, deflate the balloon and remove balloon and sheath as a unit.Note: care should be taken to monitor balloon manipulations an inflation using fluoroscopy at all times.Based on the information provided, inspection of the returned product, and the results of the investigation, a definitive cause for the leak was not established.A leak test performed on the balloon did not show any indication that there was a pinhole or tear in the balloon material that could have contributed to a leak.The appropriate personnel have been notified.Per the quality engineering risk assessment, no further action is required.Cook will continue to monitor for similar complaints.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
