ABSTRACT:
A silicone catheter wound drain with parallel lumens or passageways formed inside to convey fluid from a wound. The drain has both holes and slots on the outside surface to admit fluid to the lumens and internal openings between the lumens to divert fluid from a blocked lumen to an adjacent lumen and back again after the blockage. The silicon wound drain may contain an embedded, elongated reinforcing fiber to strengthen the wound drain and prevent necking down during removal.
