CINCOR Contrast Removal System
Another catheter is a 11-Fr aspiration catheter (CINCOR Contrast Removal
System, Osprey Medical, St. Paul, Minnesota) (Figure
7A). Duffy and colleagues were able to successfully cannulate the CS
with an aspiration catheter using a 14-Fr right internal jugular vein
sheath in 31 out of 41 recruited patients. Contrast aspiration was done
by pushing the foot pedal in this contrast removal system after coronary
contrast injection. Using inductively coupled plasma optical emission
spectroscopy, the amount of contrast extraction was measured. Those who
underwent CS aspiration, they did not observe any serious adverse events
associated with the
device (91).
This system was also successfully placed in CS ostium through a 12-Fr
femoral venous sheath in one case. After four seconds of delay post each
cine angiography acquisition, contrast extraction was done using the
11-Fr CINCOR system for 10 seconds (Figure 10A ). The procedure
was performed uneventfully and the patient did not experience an
apparent hemoglobin
drop (91,94).
