As reported, the indicator window of a 7f exoseal vascular closure device (vcd) did not change color at any point during withdrawal, even when the sheath tip was withdrawn outside the body, and closure failed.There was no reported patient injury.The device was used to close an 8f femoral artery sheath.The operating instructions were strictly followed, and the withdrawal angle was maintained during withdrawal of the sheath and closure device.During ex vivo testing, the guidewire loop required substantial pulling force, and the color-change response was insensitive.Hemostasis was achieved by compression.There were no visible signs of device or package damage prior to use.The device was stored and prepared according to the instructions for use (ifu).There was no difficulty connecting the vascular sheath introducer with the exoseal vascular closure device (vcd).The indicator wire cowling locked against the handle assembly, and an audible click was heard.Pulsatile flow was observed from the bleed-back indicator.The exoseal vcd and vascular sheath introducer were retracted together until bleed back significantly slowed or stopped.The indicator did not show a black-black state.The physician did not have their thumb on the plug deployment button during retraction.The indicator window did not show red during retraction.When the device was removed from the patient, the indicator wire loop was deployed/showing, with no anomalies noted.Deployment was attempted outside the patient's body; considerable force was required to pull the guidewire loop, and the indicator window was not sensitive to color change.An 11 cm femoral sheath was used.Femoral artery suitability was verified by angiography, including the vascular sheath introducer insertion angle of 30-45 degrees, and the vessel diameter was verified to be at least 5 mm.There was no visible calcium/plaque at the puncture site, access vessel tortuosity, stent near the puncture site, or stenosis greater than 50% at or near the puncture site.The target femoral site had not been closed with a closure device or manual compression less than 30 days before the procedure.There was no evidence of a pre-existing hematoma, arteriovenous fistula, or pseudoaneurysm at the access site before exoseal vcd use.The exoseal vcd was used in an interventional procedure with a retrograde approach.The patient's body mass index was not greater than 40.The physician had achieved certification on the use of the exoseal vcd.The device will be returned for evaluation.
