The present invention is directed to a wound drain catheter system for draining
fluid from, or supplying medication to, a wound in a patient. The system comprises
(A) a trocar having (a) a blade portion on a distal end; and (b) a connector portion
on a proximal end, the connector portion being a hollow core lying on a longitudinal
axis; (B) a drain having (a) a first connector portion on a distal end, the first
connector portion being a protrude lying on a longitudinal axis; and (b) a second
connector portion on a proximal end; (C) a flexible outflow tube having (a) a proximal
end and a distal end; and (b) a smooth exterior for sealing to surface tissue at
the point of exit from the body of a patient; and (D) means for connecting the
second connector portion of the drain to the distal end of the flexible outflow
tube. The protrude of the first connector portion of the drain engages the interior
of the hollow core of the connector portion of the trocar. The wound drain catheter
system may also include a bioabsorbable transitional part.
