The contact at the hospital reported that when the operator tried to advance the enterprise stent (enf452800/10398723) through the hub of the microcatheter (details unknown), he felt resistance and was not able to advance the stent.It was confirmed that the introducer was fully seated and secured in the catheter hub during introduction of the device into the catheter.The enterprise was removed.When it was removed there were no damages on any part of the device.Another enterprise stent (details unknown) passed through the same microcatheter.An adequate continuous flush was maintained through the catheter.There was no reported patient impact associated with the complaint.The device did not kink or bend at any time prior to the resistance/friction.The concomitant devices did not kink or bend at any time.There was no significant delay to the procedure as a result of the issue.At the time of initial contact, the product was available for return.During product analysis, the investigator discovered that the microcatheter was compressed at the distal tip.

No sterile lot number information was available thus no dhr could be performed.A non-sterile prowler select plus microcatheter was received coiled inside of a plastic bag.In addition, the involved enterprise device was observed separated from the microcatheter.The stent was found deployed inside the microcatheter.No damages were noted on the hub.The id band was found damaged.The microcatheter was inspected and a compressed section was found.The device was inspected under microscope; compressed sections were noted.The id from the microcatheter was measured and was found within specification.The functional test was performed.The prowler selplus microcatheter was flushed out using a lab sample syringe (nipro) and water came out from the distal end of the device.A 0.018¿ guide wire cordis lab sample was introduced into the microcatheter and severe resistance was felt when guide wire lab sample was passed through of compressed sections found on the device.However, the guide wire passed through the microcatheter.The enterprise lab sample cannot be inserted through the microcatheter due to the compressed sections found on the distal end tip.The failure reported by the customer that the microcatheter obstructed the stent was not confirmed during the functional test.An additional failure discovered during analysis that the brite tip/distal tip was compressed/crushed was discovered during the visual analysis.The cause of the failure experienced by the customer appears was due to the compressed section found on the device.The cause of these defects could not be conclusively determined however the analysis suggests that the failure reported could not be related to the manufacturing process.Therefore no corrective actions will be taken at this time.This report is related to mfr report reference # 1058196-2015-00114.
