<p>A continent ostomy port device (10, 100) has a face plate (12, 112, 212) defining a selectively sealable aperture (24) which is alignable with the opening of a users stoma. A closure portion (18) is adapted to permit selective and repeatable covering and uncorvering of the aperture. A catheter portion (14, 114) extends proximally from one side of the face plate, and is disposed, within the ostomy site, when the port device (10, 100) is in normal use position. The catheter has side walls (44, 46), and is sized and shaped for nonsurgical installation through a stoma and provides a barrier which reduces stoma prolapse without extraneous, externally applied materials of additional surgery. Retaining structure (16, 116, 216...) is connected to the catheter and is nonsurgically, snugly fittable into the stoma, to cause the port device to be selfretaining, and is also usefully connected to other medical catheters.</p> |
