Tubular surgical device

A tubular surgical device for insertion into a cavity of living body comprising:

• an elongated substantially hollow cylindrical tubular flexible conduit having an exterior surface for contacting tissue of the cavity;
• said exterior surface of said conduit being coated with a hydrophilic material and being impregnated with infection preventing material for absorption by the tissue of the cavity;
• said conduit having an axially extending bore, said bore extending the length of said conduit and being defined by an annular wall interior of said conduit;
• said annular wall including a plurality of axial spaced alternating annular ridges and grooves to render said conduit flexible in the area of said ridges and grooves for easy insertion of the conduit into the cavity and;
• means for delivering infection preventing material to said exterior surface of said conduit while the tubular surgical device is positioned in the cavity including a channel surrounding said bore and being disposed adjacent said annular wall;
• said channel including a plurality of apertures in fluid communication with said conduit.

A tubular surgical device for insertion into a cavity of a living body comprising:

• an elongated substantially hollow cylindrical tubular flexible conduit having an exterior surface for contact with tissue of the cavity;
• said exterior surface of said conduit being coated with a hydrophilic material and further being impregnated with infection preventing material selected from the group consisting of antibiotics and germicides for absorption by the tissue of the cavity;
• said conduit having an axially extending bore, said bore extending the length of said conduit and being defined by an annular wall interior of said conduit;
• said annular wall including a plurality of axially spaced alternating annular ridges and grooves to render said conduit flexible in the area of said ridges and grooves for easy insertion of the conduit into the cavity;
• and
• a channel surrounding said bore and being disposed adjacent said annular wall, said channel including a plurality of apertures within said conduit and said channel extending exterior of said conduit for receiving antibiotics and germicides for transporting antibiotics and germicides throughout said conduit and via said plurality of apertures to tissue in the cavity contacting said conduit exterior surface.
