It was reported that tip detachment occurred.The target lesion was located at the distal right coronary artery.A comet ii pressure guidewire was used.During procedure, there was no problem in delivering the comet ii guidewire down the distal right coronary artery.Physician then encountered resistance from the comet ii wire and would not exit the vessel.The comet ii wire was stuck at same position it was delivered.The physician continued to pull the wire to retrieve it; however, it could not be removed.The comet ii guidewire was pulled with more force and the distal part of the wire, the "radiopaque" portion, broke off in the vessel.The remaining part of the comet wire came out of the patient's body.The patient did not experience any adverse events and had been scheduled for a by-pass surgery because of triple vessel disease.Patient underwent successful coronary artery bypass grafting surgery, with no complications.The distal tip part of the comet wire was successfully removed from the right coronary artery during the by-pass procedure.

Updated e1: initial reporter details.Device evaluated by mfr: the complaint device was not received at the complaint investigation site (cis) for analysis.However, there was 4 photos in the complaint record (b)(4).All the photos were reviewed by the ah cis technician.One of the photos showed the packaging of the comet device and not the reported event.One showed the device coiled up in a biohazard bag but did not show the tip or any damage.Two other photos showed what appeared to be the distal end/tip of the wire inside the patient; however, there was not anything in the photo to confirm the reported event or any damage.Therefore, the photos were inconclusive.
