Device evaluated by mfr., eval summary attached, method codes, result codes, conclusion codes updated.Device evaluated by mfr: promus premier, us, mr 3.50 x 16mm stent delivery system (sds) was returned for analysis.A visual and tactile examination found a dry foreign matter (fm) residue (white and cloudy) 1.5cm distal from the hypobond, in patches along the midshaft, inner/ outer lumen and continued to the distal tip.The fm was non removal and could be seen with a naked eye.There was also a hypotube kink 4mm distal of hypobond.Initial analysis of the device thought that the fm residue was possibly from bioslide solution.Bioslide solution is a hydrophilic coating that is applied to the promus premier shaft to improve lubricity of the device to aid deliverability.Fourier transform infrared analysis was carried out to identify the fm residue.The testing concluded that the fm residue was not bioslide solution.Analysis could not fully confirm the origin of this dry fm residue.A visual and tactile examination found damage to the tip; stretched and jagged at the edge.A visual examination of the crimped stent found no issues with the crimped stent.There were no signs of damage; stretching or lifting of the stent struts.The balloon cone profiles were reviewed and no issues were noted with the overall balloon profile.The balloon wings were tightly wrapped and evenly folded and were not subjected to positive pressure.No other issues were identified during the product analysis.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause was unable to be determined.(b)(4).
