As reported, during angioplasty of the superficial femoral artery, a pinhole was noted in an advance 35 lp low profile balloon catheter's balloon.Another manufacturer's 6-french sheath and wire were used during the procedure.The balloon was inflated two times, using an unknown inflation device, to eight atmospheres.The balloon was not inflated within a stent.The balloon was allowed to return to ambient pressure after the hole was noted.The balloon was removed by itself while negative pressure was maintained.Details of the patient's anatomy are not available.Another balloon was used to complete the procedure.A section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.

Summary of event: as reported, during angioplasty of the superficial femoral artery, a pinhole was noted in an advance 35 lp low profile balloon catheter's balloon.Another manufacturer's 6-french sheath and wire were used during the procedure.The balloon was inflated two times, using an unknown inflation device, to eight atmospheres.The balloon was not inflated within a stent.The balloon was allowed to return to ambient pressure after the hole was noted.The balloon was removed by itself while negative pressure was maintained.Details of the patient's anatomy are not available.Another balloon was used to complete the procedure.A section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.Investigation evaluation: reviews of the complaint history, device history record, drawing, instructions for use (ifu), specifications, and quality control procedures were conducted during the investigation.A visual inspection of the complaint device was also conducted.The complaint device was returned to cook for investigation.A pinhole leak was noted in the balloon, near the distal marker band.A document-based investigation evaluation was performed.No related non-conformances were found, and there have been no other reported complaints for this lot number.The product ifu warns "do not exceed rated burst pressure.Rupture of balloon may occur.Adhere to balloon inflation pressure parameters in the compliance card insert.Over-inflation may cause rupture of the balloon, with resultant damage to the vessel wall.Use of a pressure gauge is recommended to monitor inflation pressure." the ifu also cautions "in heavily scarred access sites, use of an introducer sheath is recommended." the information provided upon review of the dmr, dhr, ifu, and investigation of the returned device suggests that there is evidence the device was manufactured to specification.There is no evidence of non-conforming devices in-house or in the field.Cook has concluded that sufficient inspection activities are in place to identify this failure mode prior to distribution.Based on the information provided and the results of the investigation, cook has concluded that a component failure, unrelated to device design or manufacturing, contributed to this event.The risk analysis for this failure mode was reviewed and no additional escalation was required.The appropriate personnel have been notified and cook will continue to monitor for similar events.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.
