The manufacturer of the BioEnterics LAPBAND
® Adjustable Gastric Banding System has designed,
tested and manufactured it to be reasonably fit for
its intended use. However, the BioEnterics
LAP-BAND System is not a lifetime
product and it may break or fail, in whole
or in part, at any time after implantation and
notwithstanding the absence of any defect. Causes
of partial or complete failure include, without
limitation, expected or unexpected bodily reactions
to the presence and position of the implanted
device, rare or atypical medical complications,
component failure and normal wear and
tear.
Just makes you think twice.
