Event Description
|
It was reported that the device became stuck on the guidewire and partially deployed outside the patient.An innova was selected for use in a stenting procedure to treat a dissection flap in the superficial femoral artery.Upon placing the stent on a 0.035 inch stiff zipwire guidewire, the device became stuck.An attempt was made to take the stent off the wire to re-flush, but in doing so, the stent partially deployed outside the body.The stent never entered the body.Eventually, the device was able to be removed from the wire.The procedure was completed with a different stent.No patient complications were reported.

Manufacturer Narrative
|
H3: device eval by manufacturer: the innova self-expanding stent system was returned to boston scientific for analysis.Visual examination revealed a kink to the outer sheath at the nosecone.The stent was partially deployed approximately 7mm from the distal end of the middle sheath.Microscopic examination revealed no additional damages.The thumbwheel lock was missing.The pull rack was still in the manufactured position.This suggests that the thumbwheel was not accidently used to deploy the stent.The information provided also indicates that the thumbwheel lock was still on the device.It is likely that something else caused the stent to partially deploy.Kinks to the sheath usually occur when the device is advancing along the wire and is met with some resistance.The information provided indicates that the wire was taken out after it got stuck which also suggest that the interactions with the guidewire likely contributed to the reported event.
