Stoma stabilitating device and method
A method and device may be used to avoid surgically re-opening a stoma or the like in an animal, including human beings. The stoma stabilitating device comprises an anchoring portion, preferably flat, that includes an opening configured to surround a stoma. The anchoring portion preferably includes an inner tension ring attached to an inner edge to define the opening and a tension ring attached to an outer edge. The anchoring portion may include additional structural rings. The device may be of a mesh construction and used to maintain, for example, a stoma, a fistula, a tracheotomy and any other pathway from outside the body to the inner part of the body. The device may be used to maintain an open pathway for air and to maneuver devices within a cavity. The device may also be used internally.
1. A stoma stabilitating device comprising:
a substantially fiat anchoring portion including an inner tension ring defining an opening configured to surround a stoma or the like, wherein the stoma stabilitating device maintains the stoma or the like such that the stoma or the like remains open;
wherein the anchoring portion constructed of a material suitable for implantation into a living animal and configured to maintain a substantially fiat orientation with the inner tension ring in a substantially fully open orientation when in use;
wherein the anchoring portion is constructed of a mesh material and includes an outer tension ring to provide tension to the mesh material of the anchoring portion disposed between the inner and outer rings such that the mesh material is maintained in a substantially fully open orientation; and
a tubular extension extending from one side of the anchoring portion at the opening, wherein the tubular extension is constructed of a mesh material, has one end attached to the anchoring portion and a second end that includes a support ring to maintain the opening defined by the anchoring portion substantially fully opened through the tubular extension.
2. The stoma stabilitating device of claim 1 wherein the outer tension ring defines an outer edge of the anchoring portion and is substantially concentric with the inner tension ring.
3. The stoma stabilitating device of claim 2 wherein the outer tension ring has a diameter between 1 cm and 25 cm.
4. The stoma stabilitating device of claim 3 , wherein the inner tension ring has a diameter between 0.5 cm and 8 cm.
5. The stoma stabilitating device of claim 1 wherein the anchoring portion comprises two mesh layers welded together at outer and inner edges.
6. The stoma stabilitating device of claim 5 wherein the rings are polydioxanone (PDO) monofilament rings.
7. The stoma stabilitating device of claim 6 wherein the PDO monofilament rings are a circular shape.
8. The stoma stabilitating device of claim 6 wherein the rings comprise washers welded between the two mesh layers.
9. The stoma stabilitating device of claim 1 wherein the outer tension ring defines an outer edge of the anchoring portion and is substantially concentric with the inner tension ring.
10. The stoma stabilitating device of claim 1 further comprising:
a second tubular extension extending from an opposite side of the anchoring portion at the opening.
11. The stoma stabilitating device of claim 10 wherein the tubular extensions are constructed of a mesh material and each tubular extension has one end attached to the anchoring portion and a second end that includes a support ring to maintain the opening defined by the anchoring portion substantially fully opened through the tubular extension.
12. The stoma stabilitating device of claim 11 wherein the outer tension ring defines an outer edge of the anchoring portion and is substantially concentric with the inner tension ring.
13. A stoma stabilitating device comprising:
a substantially flat anchoring portion including an inner tension ring defining an opening configured to surround a stoma or the like, wherein the stoma stabilitating device maintains the stoma or the like such that the stoma or the like remains open;
wherein the anchoring portion constructed of a material suitable for implantation into a living animal and configured to maintain a substantially flat orientation with the inner tension ring in a substantially fully open orientation when in use;
wherein the anchoring portion is constructed of a mesh material and includes an outer tension ring to provide tension to the mesh material of the anchoring portion disposed between the inner and outer rings such that the mesh material is maintained in a substantially fully open orientation, and wherein the outer tension ring defines a substantially continuous outer edge of the anchoring portion.
14. The stoma stabilitating device of claim 13 wherein the outer tension ring defines an outer edge of the anchoring portion and is substantially concentric with the inner tension ring.
15. The stoma stabilitating device of claim 14 wherein the outer tension ring has a diameter between 1 cm and 25 cm.
16. The stoma stabilitating device of claim 15 , wherein the inner tension ring has a diameter between 0.5 cm and 8 cm.
17. The stoma stabilitating device of claim 13 wherein the anchoring portion comprises two mesh layers welded together at outer and inner edges.
18. The stoma stabilitating device of claim 17 wherein the rings are polydioxanone (PDO) monofilament rings.
19. The stoma stabilitating device of claim 18 wherein the PDO monofilament rings are a circular shape.
20. The stoma stabilitating device of claim 17 wherein the rings comprise washers welded between the two mesh layers.
