Percutaneous implant and ostomy method
First Claim
1. A percutaneous ostomy implant for implantation into the abdominal wall of a patient, the implant comprising (a) a first cylinder of a connecting member for mounting an external detachable device thereto and being configured and dimensioned to receive an intestine segment within it to form a stoma, wherein the implant further comprises (b) a second cylinder of the same diameter as the connecting member and that includes a tubular mesh structure and a radially-extending dermal anchor comprising a radially-extending first ingrowth mesh configured and positioned on the second cylinder to engage the abdominal wall beneath and substantially adjacent to the dermis structure to secure the implant in the axial direction relative to the dermis, wherein the tubular mesh structure further includes a second ingrowth mesh located above the dermal anchor for ingrowth of dermis and a third ingrowth mesh located below the dermal anchor for ingrowth of sub-dermal tissue, and (c) an inner fourth ingrowth mesh in the form of a cylindrical tube that is of smaller diameter than the connecting member and extends below the third ingrowth mesh, with the fourth ingrowth mesh attached to an inner portion of the connecting member and spaced from the second ingrowth mesh.

Abstract
A percutaneous ostomy implant for implantation into the abdominal wall of a patient is provided, which includes a connecting member for mounting an external detachable device thereto; a first tubular ingrowth member depending from the connecting member; and a second tubular ingrowth member depending from the connecting member and being radially outwardly spaced from the first tubular ingrowth member. The first tubular ingrowth member is configured and dimensioned to receive a bowel segment within it to allow the stoma and serosal tissue of that bowel segment to infiltrate the first tubular ingrowth member. The second tubular member is configured and dimensioned to abut dermal tissue to allow the dermal tissue to infiltrate the second tubular ingrowth member, thereby securing and sealing the ostomy implant to the dermis.

- 9. A percutaneous ostomy implant for implantation into the abdominal wall of a patient, the implant comprising (a) a first cylinder of a generally cylindrical connecting member for mounting an external detachable device thereto and being configured and dimensioned to receive an intestine segment within it to form a stoma, and (b) a second cylinder of the same diameter as the connecting member and that includes a tubular mesh structure and a radially-extending dermal anchor comprising a radially-extending first ingrowth mesh configured to facilitate tissue growth and positioned on the second cylinder to engage the abdominal wall beneath and substantially adjacent to the dermis structure to secure the implant in the axial direction relative to the dermis, wherein the tubular mesh structure includes a second ingrowth mesh located above the dermal anchor for ingrowth of sub-dermal tissue, a third ingrowth mesh located below the dermal anchor for ingrowth of sub-dermal tissue, and an inner fourth ingrowth mesh in the form of a cylindrical tube that is of smaller diameter than the connecting member and extends below the third ingrowth mesh, with the fourth ingrowth mesh attached to an inner portion of the connecting member and spaced from the second ingrowth mesh, wherein a lower portion of the implant further comprises (c) a termination ring having a frusto-conical shape with an outer diameter that is not larger than that of the dermal anchor.

16. A percutaneous ostomy implant for implantation into the abdominal wall of a patient, the implant comprising:
-
a first cylinder of a connecting member for mounting an external detachable device thereto and being configured and dimensioned to receive an intestine segment within it to form a stoma, a second cylinder of the same diameter as the connecting member that includes a radially-extending dermal anchor comprising a radially-extending first ingrowth mesh configured and positioned on the second cylinder to engage the abdominal wall beneath and substantially adjacent to the dermis structure to secure the implant in the axial direction relative to the dermis, and a tubular mesh structure that includes a second ingrowth mesh located above the dermal anchor for ingrowth of sub-dermal tissue and a third ingrowth mesh located below the dermal anchor for ingrowth of sub-dermal tissue, and an inner fourth ingrowth mesh in the form of a cylindrical tube that is of smaller diameter than the connecting member and extends below the third ingrowth mesh, with the fourth ingrowth mesh attached to an inner portion of the connecting member and spaced from the second ingrowth mesh; wherein the second ingrowth mesh is attached to an outer portion of the connecting member and axially spaces the dermal anchor from the connecting member. - View Dependent Claims (17, 18, 19, 20)
