Manufacturer Narrative
|
Device evaluated by mfr.: express-b-i ld, pmtd, 8.0x30x135cm was received for analysis.The recommended introducer sheath size for this express ld device as per express specification is a 6fr.The sheath used by the customer was not returned for analysis.During analysis the investigator was unable to advance the device through a 6fr boston scientific sheath as the stent was no longer crimped to the balloon material.A visual examination of the returned device confirmed that the balloon was tightly wrapped and had not been subjected to positive pressure.No issues were noted with the balloon material.A visual examination found the stent in the correct location on the balloon.Although in the correct position the stent was found to be no longer crimped to the balloon material suggesting that the stent had been moved on the device.This could potentially have occurred when attempting to advance the device through the sheath.No issues were noted with the tip of the device.A visual and tactile examination identified no issues along the length of the device.This concludes the product analysis.
