Manufacturer Narrative
|
E1 initial reporter phone: (b)(6).Device evaluated by mfr.Promus premier ous mr 28 x 4.00mm stent delivery system catheter was returned for analysis.Visual, tactile and microscopic analysis was performed on the device.Visual inspection revealed that the device was received with the stent detached from the balloon.The first 3 rows on both the proximal and distal ends of the stent did not appear damaged.However, the remainder of the stent found that the stent was stretched with stent struts misaligned.A visual examination of the balloon material could not identify that the balloon had been inflated.There was clear evidence of stent crimp on the balloon material.No issues were identified with the hypotube shaft.A visual and tactile examination of the outer and inner lumen and mid-shaft section found no issues.The bumper tip showed no signs of distal tip damage.Microscopic analysis of the detached crimped stent found that the first 3 rows on both the proximal and distal ends of the stent did not appear damaged.However, the remainder of the stent found that the stent was stretched with stent struts misaligned.It is not clear from the damage to the stent if the stent had been deployed or simply pulled off the balloon.A microscopic examination of the balloon identified no damages.There was no inflation media present inside the balloon.
