Abstract
A surgical gravity drain includes biologically inert medical grade silicone rubber extruded to generally parallel longitudinally extending planar surfaces having transversely aligned and longitudinally extending capillary drainage channels. A ribbon of silicone rubber including integrally formed longitudinally extending and laterally spaced ribs defining transversely aligned capillary drainage channels on external ribbon surfaces is disclosed in one embodiment; and a flattened tube of silicone rubber including integrally formed longitudinally extending and laterally spaced ribs defining transversely aligned capillary drainage channels on internal and external tube surfaces is disclosed in a further embodiment. The novel drain of the present invention is substantially clogging-free, collapse-proof, and provides effective long term in situ drainage.
