Stoma control device and method
First Claim
1. A stoma control device comprising, in combination, support means for surgical implantation in the body beneath the abdominal wall and at least substantially around the emerging bowel of a stoma, said support means being adapted to be fastened securely to the abdominal wall and to extend a predetermined distance along said bowel, and said support means including an at least substantially continuous inner wall means having an inner surface which is positioned adjacent said bowel on implantation and which is tapered outwardly along at least most of the length of said support means, and said support means having an end surface for positioning adjacent the abdominal wall, and plug means adapted to be received in said stoma and within said bowel, said plug means including outwardly directed flange means adjacent one end for cooperation with the outer surface of the body about the stoma and expandable means adjacent the other end, said expandable means, on expansion, presenting an outer surface which is outwardly tapered with a shape which complements the outwardly tapered inner surface of said support means over at least most of the length of said support means whereby during control of the stoma with said device a relatively large surface of the bowel may be gently compressed between the respective tapered surfaces of the plug means and the support means so as to minimize pressure and tissue destruction and to produce a wedging action of the plug means within the bowel and support means to close the stoma and to prevent expulsion of the plug means from pressure within the bowel.

Abstract
A stoma control device and method are disclosed. The device comprises, in combination, a support such as a ring for surgical implantation in the body beneath the abdominal wall and substantially around the emerging bowel of a stoma, the support being formed of a relatively soft material such as soft plastic and having an inner surface which tapers outwardly to present a relatively large supporting surface for the bowel, and a plug adapted to be received in the stoma and within the bowel for controlling the stoma, the plug including an inflatable balloon, the balloon, on inflation, presenting an outwardly tapered surface with a shape which complements the tapered inner surface of the support whereby during control of the stoma with the device a relatively large surface of the bowel may be greatly compressed between the plug and the support so as to minimize pressure and tissue destruction.

- 1. A stoma control device comprising, in combination, support means for surgical implantation in the body beneath the abdominal wall and at least substantially around the emerging bowel of a stoma, said support means being adapted to be fastened securely to the abdominal wall and to extend a predetermined distance along said bowel, and said support means including an at least substantially continuous inner wall means having an inner surface which is positioned adjacent said bowel on implantation and which is tapered outwardly along at least most of the length of said support means, and said support means having an end surface for positioning adjacent the abdominal wall, and plug means adapted to be received in said stoma and within said bowel, said plug means including outwardly directed flange means adjacent one end for cooperation with the outer surface of the body about the stoma and expandable means adjacent the other end, said expandable means, on expansion, presenting an outer surface which is outwardly tapered with a shape which complements the outwardly tapered inner surface of said support means over at least most of the length of said support means whereby during control of the stoma with said device a relatively large surface of the bowel may be gently compressed between the respective tapered surfaces of the plug means and the support means so as to minimize pressure and tissue destruction and to produce a wedging action of the plug means within the bowel and support means to close the stoma and to prevent expulsion of the plug means from pressure within the bowel.

22. A stoma control device comprising, in combination, support means for surgical implantation in the body beneath the abdominal wall and at least substantially around the emerging bowel of a stoma, said support means being adapted to be fastened securely to the abdominal wall and to extend a predetermined distance along said bowel, and said support means including an at least substantially continuous inner wall means having an inner surface which is positioned adjacent said bowel on implantation and which defines an opening through which the bowel passes, the cross sectional area of said opening increasing in a direction into said stoma over at least most of the length of said support means, and said support means having an end surface for positioning adjacent the abdominal wall, and plug means adapted to be received in said stoma and within said bowel, said plug means including outwardly directed flange means adjacent one end for cooperation with the outer surface of the body about the stoma and expandable means adjacent the other end, said expandable means, on expansion, presenting an outer surface whose cross sectional area increases in a direction into said stoma over at least most of the length of said support means and in a manner similar to the increase in cross sectional area of said opening defined by said inner surface of the support means whereby during control of the stoma with said device a relatively large surface of the bowel may be gently compressed between the plug means and the support means so as to minimize pressure and tissue destruction and to produce a wedging action of the plug means within the bowel and support means to close the stoma and to prevent expulsion of the plug means from pressure within the bowel.

23. A method of controlling a stoma comprising the steps of surgically implanting a support means in the body beneath the abdominal wall and at least substantially around the emerging bowel of a stoma by securely fastening said support means to the abdominal wall, said support means including an at least substantially continuous inner wall means having an inner surface which is positioned adjacent the bowel, said inner surface being tapered outwardly along at least most of the length of said support means, and said support means having an end surface which is positioned adjacent the abdominal wall, inserting a plug means in said stoma and within said bowel, said plug means including outwardly directed flange means adjacent one end and expandable means adjacent the other end, said expandable means, on expansion, presenting an outer surface which is outwardly tapered with a shape which complements the outwardly tapered surface of the support means over at least most of the length of said support means, and expanding said expandable means to gently compress a relatively large surface of the bowel between the respective tapered surfaces of the plug means and the support means whereby pressure and tissue destruction are minimized during control of the stoma and a wedging action of the plug means within the bowel and support means is produced to close the stoma and prevent expulsion of the plug means from pressure within the bowel.
