Event Description
|
It was reported that catheter twist occurred.Vascular access was obtained using radial access with a retrograde approach.Following a successful de-clot of a non-boston scientific graft, an opticross peripheral imaging catheter was advanced to verify results and complete the procedure.The catheter was placed across the lesion and while imaging was being initiated, the screen gave a motor drive unit (mdu) overload error and the mdu shut down.An attempt was made to reinitiate imaging, but the mdu message returned.The catheter tip was visualized using angiography and it could be seen that the catheter had become wrapped around the wire distal to the sheath.An attempt was made to remove the catheter from the arm however, it would not pass into the sheath.The physician cut both the catheter and wire outside the patient and used force to pull the entanglement through the sheath and out of the patient.No patient complications were reported and the procedure was considered successful.

Manufacturer Narrative

The device was returned for analysis.Visual inspection revealed a catheter twist in the lap joint section, a cut in the imaging window, and kinks in the imaging window and sheath.The catheter was properly recognized by the imaging system when plugged into the motor drive unit and no connection issues or errors were detected during its testing.A picture provided by the site was inspected and it showed evidence of a twist in the imaging window.
