Abstract:
1. An ostomy port for conducting waste content from an intestinal portion in an abdominal cavity through a stoma in an abdominal wall comprising: a cover for covering the stomal tissue external to an abdominal wall, said cover extending around a proximal opening of said ostomy port and being connected to a pliable, axially elastic tube in communication with said proximal opening; said tube being of a length to extend longitudinally from a proximal side connected with said cover pass along a length of intestine extending distally from said stoma and cross said abdominal wall such that said tube reaches a visceral side of said abdominal wall; said tube interconnecting said cover with a fixation element for anchoring the port to said visceral side of the abdominal wall, said anchoring of the port comprising the fixation element having an expanded cross-section, upon said anchoring, too large to pass proximally through said length of intestine; said length of said tube being sized and configured such that, when said cover and said fixation element are interconnected across said abdominal wall, a tensile force acts through said tube along said longitudinal extent upon said cover and upon said fixation element, whereby said fixation element is drawn toward an interior side of said abdominal wall to seal against leakage around said fixation element at the tissue interface to which said fixation element is drawn, and whereby said cover is drawn against the exterior of said abdominal wall; said tube being sufficiently pliable for being radially and reversibly collapsible upon constriction within said length of intestine, and said tube being axially elastic such that it extends upon relative movement of said cover and said fixation element, due to displacement by changes in tissue position while inserted across said abdominal wall; said extending provided while remaining below a predetermined maximum level of said tensile force; and a cap for sealing said proximal opening; wherein said cap includes a shell for accommodating a waste content collection bag.
