Abstract

An implant that has a tubular interior section for implantation into a patient, an exterior section connected to the interior section and an ingrowth member that includes a three-dimensional porous structure. The three-dimensional porous structure is typically located at the inner circumference of the interior section and has desirable properties to facilitate ingrowth of tissue.

Claims

1-57. -57. (canceled)

58. An implant comprising a tubular interior section for implantation into a patient and an exterior section connected to the interior section, the implant comprising ingrowth means that includes a three-dimensional porous structure.

59. The implant of claim 58, wherein a surface of the exterior section comprises a three-dimensional porous structure at an inner circumference thereof.

60. The implant of claim 58, wherein the porous structure is rigid.

61. The implant of claim 58, wherein:

the porous structure is integral with the rest of the exterior section;

or

there is no gap between the porous structure and the rest of the exterior section;

or

the porous structure is connected to the exterior section at least at first and second end regions thereof;

or

the porous structure extends to within 1 mm, 2 mm or 3 mm of an exterior end of the exterior section;

or

the porous structure is arranged around the entire inner circumference of the exterior section.

62. The implant of claim 58, which is a percutaneous ostomy implant for implantation into the abdominal wall of a patient.

63. The implant of claim 58, wherein the exterior section is ring-shaped.

64. The implant of claim 58, wherein the porous structure is made from titanium.

65. The implant of claim 58, wherein the ingrowth means or the porous structure of the ingrowth means has a thickness of at least 0.5 mm.

66. The implant of claim 58, wherein the porous structure is completely permeable and has no dead ends.

67. The implant of claim 58, wherein at least 80%, at least 85%, at least 90%, at least 95%, or at least 97% of the openings into the porous structure have a corresponding exit, or each passage entering the porous structure has an exit.

68. The implant of claim 58, wherein the porous structure is formed of interconnecting members, each member forming the porous structure having a thickness that is less than or equal to 500 μ

m, less than or equal to 450 μ

m, less than or equal to 400 μ

m, less than or equal to 350 μ

m, or less than or equal to 300 μ

m.

69. The implant of claim 58, wherein each opening in the porous structure has a maximum diameter of 500 μ

m, 450 μ

m, 400 μ

m, 350 μ

m, or 300 μ

m.

70. The implant of claim 58, wherein the three-dimensional porous structure of the ingrowth means comprises a plurality of interconnecting members, and the interconnecting members form a regular, repeating pattern throughout the porous structure or an irregular structure, and are optionally arranged concentrically.

71. The implant of claim 58, wherein the tubular interior section has first and second ends;

the exterior section has first and second ends and a body for attachment to an adaptor or other removable device, with the second end of the exterior section connected to the first end of the interior section, with the exterior section having inner and outer surfaces extending between the first and second ends; and

the three-dimensional porous structure of the ingrowth means configured and dimensioned to fit within the inner surface of the exterior section.

72. The implant of claim 58, further comprising an anchoring flange extending radially outwardly from the interior section, optionally in the form of a mesh.

73. An implant as claimed in claim 58, in combination with a mating lid, bag and/or evacuation device.

74. A kit comprising an implant and an adaptor for securing a bowel segment outside a patient'"'"'s body after an ostomy has been performed, wherein the implant is as claimed in claim 58, and the adaptor optionally comprising attachment means for attaching the adaptor to the implant;

and securing means to which a bowel segment may be attached.

75. The kit of claim 74, wherein a tubular body of the adaptor has first and second ends, and is configured and dimensioned to receive an exterior portion of an implant therein;

with the adaptor further comprising a radially extending part connected to the body that includes the securing means for receiving a bowel segment for attachment thereto.
