Initial analysis: the involved catheter lot# are unknown.A review of the mfg.Lot build database for the "potential" lot numbers was performed.The results recorded 41237-06 lot# 76-598-sj (mfg.05/2017) showed (b)(4) units; 77-248-y1 (mfg.05/2017) showed (b)(4) units and 41239-06 lot# 80-702-jw (mfg.08/2017) showed (b)(4) units were all mfg., tested including 100% inflation testing, inspected and released.There were no exception documents generated during the lot builds.The involved catheter devices were not returned.One (1) packaged 41239-06 7f td torque-line catheter, lot# 80-702-jw and one (1) packaged 41237-06 8f td torque-line catheter, lot# 76-598-sj.Were returned for investigation.Qe investigation: dimensional analysis of the two returned unused catheters recorded no out of spec conditions.Functional performance testing including inflation cycle testing was performed per the applicable specifications.The results recorded each of the catheters balloons successfully met the 100 cycle inflation testing.There were no functional and or performance issues replicated.Findings: engineering testing and analysis of the returned (unused) catheters recorded no performance and or out of spec conditions.
