Abstract
A implantable wound drain device includes an annular outer wall, a central core defining at least one longitudinal axis and being disposed within and spaced radially inwardly from the outer wall, and radial inner walls disposed within the outer wall and extending between and connected to the central core and outer wall such that adjacent pairs of the inner walls together with the outer wall form a plurality of elongated lumens for draining fluids therefrom from the wound. The lumens are circumferentially spaced from one another about and extend along the longitudinal axis such that the inner walls are disposed between adjacent pairs of the lumens. Each inner wall has an elongated duct defined therein extending along the longitudinal axis and extending outwardly from adjacent to the central core to the outer wall and define an entrance to the duct through the outer wall to permit fluid flow from the wound exteriorly of the outer wall through the entrance and into the duct. Thus, each duct is disposed in a respective one of the inner walls disposed between the adjacent pairs of lumens. Also, one or more interior portals may be defined in spaced apart relation from each other through at least the inner walls adjacent to the central core and preferably also through the central core.
