ABSTRACT:
A tubular surgical device (10) is provided for insertion into a cavity of a living body. The device (10) includes an elongated substantially hollow cylindrical tubular flexible conduit (12) having an exterior surface (14) for contact with the tissue of the cavity. The external surface (14) is coated with a hydrophilic material and is impregnated with an infection preventing material for absorption by the tissue of the cavity. The conduit (12) includes a bore (20) which is defined by an annular wall (22). The annular wall includes a plurality of axially spaced alternating annular ridges (24) and grooves (26) to render the conduit (12) flexible. A delivery system (42, 44, 46) is provided for the tubular surgical device (10) for supplying, replenishing, and delivering antibiotics and germicides to conduit (12) for absorption by the cavity tissue.
