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.

Claims

1. 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 and having an axially extending bore, said bore extending the length of said conduit and being defined by an annular wall interior of said conduit; 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.

2. The tubular surgical device of claim 1 wherein said exterior surface of said tubular flexible conduit includes a coating of hydrophilic material.

3. The tubular surgical device of claim 1 wherein said exterior surface of said tubular flexible conduit includes antibiotics and germicides for preventing infection of the tissue in the cavity.

4. 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.

5. The tubular surgical device of claim 4 wherein said infection preventing material is selected from the group consisting of antibiotics and germicides.

6. The tubular surgical device of claim 4 and further including:

means disposed adjacent said annular ridges for preventing material transported by the tubular surgical device from collecting in said grooves.

7. 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.

8. The tubular surgical device of claim 7 and further including:

means disposed adjacent said annular ridges for preventing material transported by the surgical tubular device from collecting in said grooves.
