Percutaneous ostomy implant

Abstract

A method of providing a stoma with a removable connection for a receptacle includes securing an implant onto the stoma of a patient, wherein the implant has an axial interior section for fixation inside the body and an axial exterior section extending outwards from the body, a free end of the exterior section accommodates mounting of a detachable device, and a distal portion of the interior section includes an anchoring section, extending radially from the distal portion of the interior section. The anchoring section has an inner anchoring ring, an outer anchoring ring and at least one connection member configured and dimensioned for resiliently connecting the inner and outer anchoring rings in a manner to provide axial resilience and anchorage to the anchoring section such that the anchoring section is able to respond to movements and absorb the shear of the implant in relation to adjacent organs.

1 . A method of providing a stoma with a connection for a detachable device, which method comprises securing an implant onto the stoma of a patient, wherein the implant comprises:
 an axial interior section for fixation inside the body, an axial exterior section in communication with the interior section and extending outwards from the body with a free end, said free end of the exterior section serving for mounting of a detachable device, and a distal portion of the interior section opposite the exterior section is provided with an anchoring section, extending radially from the distal portion of the interior section; and   wherein the anchoring section comprises an inner anchoring ring extending from or integral with the interior section, an outer anchoring ring, and at least one connection member configured and dimensioned for resiliently connecting the inner anchoring ring with the outer anchoring ring in a manner to provide axial resilience and anchorage to the anchoring section such that the anchoring section is able to respond to movements and to absorb the shear of the implant in relation to adjacent organs.   
     
     
         2 . The method according to  claim 1 , wherein the outer anchoring ring has an inner diameter that is greater than the outer diameter of the inner anchoring ring and each connection member has a shape that defines at least one gap or opening between the inner anchoring ring and the outer anchoring ring. 
     
     
         3 . The method according to  claim 2 , wherein at least two connection members are provided, each extending from the inner ring to the outer ring in a plane therebetween to provide said axial resilience and anchorage to the anchoring section. 
     
     
         4 . The method according to  claim 3 , wherein each connection member defines a gap having first and second gap parts that are of different lengths and which delimit and overall elongated circumferential gap between the inner anchoring ring and the outer anchoring ring. 
     
     
         5 . The method according to  claim 1 , wherein the anchoring section extends from the distal portion of the interior section at an angle a of approximately 90-110° and the anchoring section extends from the distal portion of the interior section at an angle a of approximately 90°. 
     
     
         6 . The method according to  claim 1 , wherein at least one of the inner anchoring ring, the outer anchoring ring or the at least one connection member has a substantially circular cross-section. 
     
     
         7 . The method according to  claim 1 , wherein a lower face of the anchoring section is covered with a polypropylene or tissue mesh. 
     
     
         8 . The method according to  claim 7 , wherein the mesh is adhered to the inner anchoring ring and the elongated connection members by means of a biological acceptable glue. 
     
     
         9 . The method according to  claim 8 , wherein the mesh has a central portion which is either of a different pore structure or a different thickness than the rest of the mesh or is saturated with glue. 
     
     
         10 . The method according to  claim 8 , wherein the central portion has a guiding hole. 
     
     
         11 . The method according to  claim 1 , wherein at least one surface on the anchoring section is coated with a biologically acceptable tissue glue and the anchoring section and glue are covered by a peelable foil. 
     
     
         12 . The method according to  claim 1 , wherein the anchoring section comprises an axially resilient circumferential spring means. 
     
     
         13 . The method according to  claim 1 , wherein the at least one connection member is configured and dimensioned for resiliently connecting the inner anchoring ring with the outer anchoring ring with a spring force that provides axial resilience and anchorage to the anchoring section. 
     
     
         14 . The method of  claim 1 , further comprising mounting a detachable device on the free end of the exterior section. 
     
     
         15 . The method of  claim 14 , wherein the detachable device is a cap or pouch. 
     
     
         16 . The method of  claim 1 , comprising fixing the axial interior section inside the body. 
     
     
         17 . The method of  claim 16 , wherein the axial interior section is fixed inside the body with tissue glue or sutures. 
     
     
         18 . The method of  claim 1 , comprising anchoring the implant with the anchoring section. 
     
     
         19 . The method of  claim 18 , wherein the anchoring section is secured in situ with sutures, tissue glue and/or staples. 
     
     
         20 . The method of  claim 18 , wherein the implant is anchored with the anchoring section subcutaneously. 
     
     
         21 . The method of  claim 1 , wherein the anchoring section is located on top of a vessel wall or fascia. 
     
     
         22 . The method of  claim 21 , the vessel wall being a vessel wall of the intestines or bladder. 
     
     
         23 . The method of  claim 1 , wherein the stoma is an opening in an abdominal wall.
