Per rep 11mar2021: after the physician deployed the stent in the left iliac, the 1st 75 % of the proximal stent deployed well and fully open.Then the distal 25 % of the stent did not fully open and remained compressed.After seeing this, the physician tried to balloon that part of the stent multiple times but each time, after ballooning, the stent would just compress again.After this, the physician had to line the inside of the stent with a competitive stent.8fr sheath used rather than the recommended 7fr no adverse effect reported as a result of this occurrence examples of rpn prefixes (but not limited to): zib5, zib6, ziv5, zisv6, zvt7, ziv6.General questions for complaint occurring during use, request the following: where was the access site?: left groin.What was the patient¿s anatomy? i.E.Scarred, tortuous, calcified, etc.: somewhat tortuous, possibly scarred.What was the target location for the stent?: left iliac.Was the target location severely calcified or tortuous?: tortuous.Was the device flushed prior to use?: yes.Were there any difficulties deploying the stent?: no.Was the stent fully deployed before removing the delivery system from the patient?: yes.What other devices were used in the procedure?: phillips ivus, a bard atlas balloon, wires, 8fr sheath.Please provide manufacturer, model, brand, and size if possible.: phillips ivus, a bard atlas balloon, wires, 8fr sheath.Were any additional procedures necessary as a result of this event?: no.Can any photos, images, or reports of the procedure or device be provided?: no.Please review following ¿failure¿ modes with contact to determine if additional questions apply.If the event involves thombosis, restenosis, and/or occlusion, request the following: n/a.Did the patient have any risk factors for thrombosis, restenosis, or occlusion? what other medications and/or treatments was the patient receiving? if occlusion occurred, can it be confirmed if the occlusion is related to thrombosis or restenosis? if the event involved claudication / pain, request the following: is the reported event a symptom of restenosis or thrombosis?: no.If no restenosis or thrombosis occurred how it was determined that the zilver stents caused / contributed to the event?: the stent would not fully open.If the event involves stent shortening, request the following: n/a.Was there any evidence of post deployment stent compression or deformation? was the delivery system able to be advanced to the target site easily / with no resistance? was the handle pulled toward the hub while the delivery system remained stationary during deployment? if the event involves sheath separation, request the following: n/a.Was there high resistance encountered during any part of the procedure, wire guide advancement, stent deployment, etc.? was pre-dilatation conducted prior to stent deployment? was the handle puled toward the hub while the delivery system remained stationary during deployment? if the event involving deployment difficulties, request the following: n/a.Was the stent eventually deployed? was pre-dilatation conducted before stent deployment? was the handle pulled toward the hub while the delivery system remained stationary during deployment? if the event that involve device stuck on wire guide, difficult to advance / remove delivery system and/or wire guide, request the following: n/a.Was the wire guide hydrophilic or non-hydrophilic? how long was the procedure 0from advancing delivery system to the moment when the user attempted to remove the device? was the wire guide new or was the wire guide used previously before advancing the zilver delivery system? if used, was the wire guide wiped between uses? was the device used percutaneously? n/a,yes,no: yes.Where on the patient was the percutaneous access site?: groin.What disease pathology was being treated? may thurner, acute or chronic obstruction, restenosis, other?: chronic obstruction.If other, please specify was the lesion approached via contralateral or ipsilateral? n/a, contralateral, ipsilateral: ipsilateral.Was pre-dilation performed ahead of placement of the stent? n/a, yes, no: yes.Did the user remove slack in the delivery system before deployment, per ifu? n/a, yes, no: yes.Was the delivery system damaged/kinked/twisted during deployment? n/a, yes, no: no.Please specify if yes.N/a.
