Event Description
|
It was reported that partial deployment occurred, and the stent stretched.Vascular access was gained via contralateral approach.The 100% stenosed target lesion was located in the mildly tortuous and moderately calcified superficial femoral artery (sfa).A 6x120, 130 cm eluvia drug-eluting vascular stent system was selected for use.The lesion was predilated.Resistance was felt during advancement of the eluvia.The thumbwheel was turned around a few centimeters deploying approximately 11cm of the stent with 1cm remaining.The shaft was pulled, and the stent stretched a little, but there was no change in shape.The stent ultimately deployed, and post dilation was performed.The guidewire was stuck in the eluvia catheter shaft; therefore, the guidewire and the delivery system were removed together as one unit.No additional treatment was performed.There were no patient complications.

Manufacturer Narrative

Device evaluated by mfr: the returned product consisted of an eluvia self-expanding stent system with an unknown 0.014 inch guidewire stuck in the device.The outer sheath, tip, inner sheath and the remainder of the device were checked for damage.Visual examination revealed that the sheath is kinked at the nosecone.The pull rack is separated at the handle.The proximal section of the separated pull rack did not return for analysis.Microscopic examination revealed no additional damages.The stent was deployed and did not return for analysis.The handle was x-rayed, and the proximal inner was prolapsed.Inspection of the remainder of the device, revealed no other damage or irregularities.There is evidence the device was used contrary to product labeling per the instructions for use (ifu).The ifu states: a stiff 0.035 in guidewire is strongly recommended for deployment of the stent, especially for tortuous anatomy and contralateral approaches.Use of undersized guidewires may lead to insufficient support of the device which can compromise stent delivery.The use of an undersized guidewire during deployment would lead to insufficient support and cause the proximal inner to prolapse.Prolapsing of the proximal inner would cause deployment issues and damage to the stent if the stent did not fully deploy when the device is pulled out.
