Abstract:
A continent ostomy port device comprising:(a) a low profile 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 device when the face plate of the 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 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 insertion 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 or additional surgery; and(d) retaining structure connected to the catheter, the retaining structure being non-surgically, snugly fittable into the stoma, to cause the port device to be self-retaining in a normal use position within a stoma of the user, without the need for special surgery and extraneous external fixation materials such as tape, belts, and adhesives; wherein the retaining structure is bioresponsive, to thereby permit the port device to be indwelling for extended periods of time, at least in the order of days, without causing tissue irritation or damage around the stoma.
