Event Description
|
It was reported that catheter entanglement occurred.An opticross imaging catheter was selected for use on the severly calcified lesion.It was noted that during the procedure, lost image had occurred during pullback because the tip of the catheter got caught on the edge of the stent and the screen became black.The procedure was completed with another of the same device.No patient complications were reported.

Manufacturer Narrative

The device was returned for analysis.Visual inspection observed that guide wire exit hole had damage.In order to inspect for imaging core indup at the proximal end of the catheter, the hub rotator retainer clip was removed.The rotator and imaging core assembly were pulled out from the removed hub.Imaging core windup began 22.0cm and 22.5cm from the distal end of the connector shaft.No other visual damages were encountered upon visual inspection.The distal housing of the transducer was observed complete and with no shattered pieces.The guidewire exit port was observed damaged.The mdu and ilab system were used to perform a functional inspection on the device along with the above referenced calibrated equipment.Impedance testing revealed an electrical open at proximal wave form.During image characterization testing, no image appeared in the ilab system.
