1. A self-retaining continent ostomy port device comprising:

  • (a) a face plate defining a selectively sealable aperture which is alignable with the opening of a stoma formed in the body of a user of the port device when the face plate of the port device is disposed substantially parallel to the body wall of the user, over the site of the stoma, to thereby provide access to the inside of the stoma;

    (b) a closure portion connectable to the face plate adjacent to the aperture and adapted to permit selective and repeatable covering and uncovering of the aperture in the face plate;

    (c) a catheter portion having a first end and a second end, the first end of the catheter portion being connected to and extending from a side of the face plate which is disposed proximally when the port device is in normal use position, the catheter portion extending proximally and the second end of the catheter portion being disposed interior of the user'"'"'s body, within the ostomy site when the port device is in normal use, the catheter portion having a continuous exterior side wall, and a continuous interior side wall defining a major lumen, the major lumen extending continuously from the aperture in the face plate to the second end of the catheter portion, the catheter portion being sized and shaped appropriately for non-surgical installation through a stoma to a sufficient distance that the presence of the catheter portion within the stoma provides a physical barrier which reduces prolapse without the use of extraneous, externally applied materials and devices or additional surgery; and

    (d) a retaining structure on the exterior side wall of the catheter, the retaining structure being a bolster formed around at least a portion of the exterior side wall of the catheter, the bolster being formed of a foam material which expands upon installation of the port device into the body of a user and formed to provide a secure but comfortable seal internally of the body of the user, proximal to the stoma site at which the port device is installed and being snugly fittable within the stoma, the bolster being formed in a cone shape and disposed coaxially on the exterior side wall of the catheter, the small end of the cone shape being disposed distally and the large end of the cone shape being disposed proximally when the port device is in a normal use position, the retaining structure being adapted to thereby permit the port device to be indwelling for at least a period of days, without the need for extraneous fixation devices such as tape, belts, and adhesives or revisionary surgery.
