ABSTRACT:
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.
