C2 CryoBalloon
The C2 CryoBalloon pro-
vides a quick and easy
way to target and ablate
unwanted tissue in
patients with Barrett's
esophagus, while sparing
healthy tissue.
A handheld touchscreen
helps guide the insertion
of a balloon-containing
catheter through a thera-
peutic endoscope. Once
it's properly situated,
physicians can use foot pedals to inflate or deflate the balloon, and
position the diffuser. When the balloon is inflated, the diffuser is posi-
tioned inside of it at the ablation site. Foot pedals allow the diffuser to
be moved or rotated.
The diffuser then "paints" a thin line of nitrous oxide on the sur-
face to be ablated and freezes it on contact. If the target patch is
larger, you simply rotate the diffuser and do another ablation next to
the first one.
The nitrous comes in ready-filled storable cartridges, so no filling is
required. Just unscrew the cap to put a new one in.
The company points to clinical studies showing that 95% of patients
treated with the device achieve complete eradication of dysplasia, and
90% have complete eradication of intestinal metaplasia through 2
years.
