BOTH DOCTORS (B)(6) AT (B)(6) SAID THAT THEY ARE CONCERNED ABOUT THE ACCURACY OF THE LENGTH OF OUR SYSTEM. DR (B)(6) SAID THAT "THEY (THE GROUP) ARE ALL TALKING ABOUT IT, AND THEY DON'T BELIEVE IT." WHEN I DID A CASE WITH DR (B)(6) HE PLACED A 23 MM ABBOTT STENT, AND WHEN I MEASURED IT, THE SYSTEM MEASURED 27 MM. SO I WENT BACK AND LOOKED AT DOCTOR (B)(6) CASE FROM THE DAY PRIOR, AND THAT WAS A 26 MM BIOTRONIC STENT, AND IT MEASURED 26 MM EXACTLY. (I DID NOT GET THE OPPORTUNITY TO SHARE THIS […]

A RECENT CONVERSATION AMONGST CLINICAL SPECIALISTS PROMPTED ME TO REVIEW EACH RUN IN THE CONSOLE FOR REPETITIVE/STACKED FRAMES AND I FOUND THAT IN 26 OF THE 28 RUNS FROM 16 CASES HERE HAD DISTAL FRAMES STACKED/FAILURE TO PULL BACK BEFORE GENERATING IMAGES.

WHILE DOING A CASE WITH DR (B)(6) YESTERDAY, HE WAS VERY UNHAPPY WITH THE LONGITUDINAL MEASUREMENTS. HE DID NOT BELIEVE THE PRE (WHICH I MEASURED AT 26 MM, AND HE THOUGHT IT REALLY SHOULD BE 28 OR EVEN 30MM). EVEN TO THE POINT THAT HE WANTED TO DISCUSS AFTER THE CASE. (IT WAS TOWARDS THE DISTAL END OF THE RUN). THE POST STENT MEASUREMENTS WERE OFF ALSO, WHICH I DID NOT BRING TO HIS ATTENTION. HE HAD PLACED A 28MM ABBOTT STENT, AND IT MEASURED 31MM. BOTH OCT RUNS AND LOGS WERE UPLOADED TO BOX.
Where this fits
This page is a record, not medical advice and not a safety rating. It copies FDA's fields and FDA's statement, and lists what the statement's text mentions. Read the labeling before relying on any of it.

A device's authorized use is a sentence the record can be read against. What Apodicta does on a medical record is that reading: every line of a note, a claim or a report proved to its source or held, before it renders.
