Manufacturer Narrative

Device evaluated by mfr: the promus premier ous mr 24 x 2.75mm stent delivery system was returned for analysis.A visual examination of the stent found proximal and mid-stent damage, with stent struts lifted and pulled distally.The undamaged crimped stent outer diameter (od) was measured and the result was within maximum crimped stent profile measurement.The balloon cones were reviewed and damage was identified on the proximal balloon cone, at the site of the proximal stent damage.The balloon wings showed no signs of inflation.A visual and microscopic examination of the bumper tip showed no signs of damage.A visual and tactile examination of the hypotube shaft found multiple hypotube kinks at several locations along the hypotube shaft.A visual and tactile examination of the outer and mid-shaft section and a visual examination of the inner lumen found no issues with the extrusion shaft.Functional testing revealed that a recommended guidewire loaded via the distal tip without issue.The returned device was attached to an encore inflation device and an attempt was made to inflate the device to rated burst pressure, however pressure could not be maintained over 4atm due to a leak identified at the proximal balloon cone.No other issues were identified during analysis.
