Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an imp-1 ant dev device.
ice).

It is often necessary to perform an enterostomy on a patient. Enteroplasty involves the externalization of an internal tube. Common tubes that normally need to be exited are the ileum (eum) + colon (c).
olon, ureter, and bladder. Traditionally, when performing enteroplasty, the snow to be expelled is cut, and then the wall of the tube is sutured to the hole made in the body or surface.

The hole is usually formed in the lower abdomen. Generally, the walls of the tube and the subcutaneous tissue and muscles surrounding the hole will grow together, thereby permanently anchoring the tube to the surface of the body. After the surgical site has healed, the container is attached to the skin surface. This container serves to contain the waste discharged from the tube.

Referring now to FIG. 1, the implant device, designated generally by the reference numeral l, consists of a passageway 8 and an anchoring means 15 for establishing a biological anchorage.

Preferably, the anchoring means 15 has a plurality of apertures 89 which encourage and advance fiber conduit ingrowth 81.

The channel 3 has an inlet area 5, which starts at an inlet 9 and ends at a seedling opening 11.

The central axis 35 passing through the center of the passageway inlet 9 is about q3 with respect to the central axis #88 passing through the center of the passageway outlet 11.
Tilt within the range of g to 7s degrees (in Figure 1, angle ''
X"), so that the implant device l will be connected to the ureter 13 without occluding or tangling the ureter 18, thereby restricting the flow through the ureter 18. , or be prevented from doing so.

In FIG. 1, the implant device 1 is shown connected to a ureter 13 extending from a kidney 21. As shown in FIG.

The implant device l is attached to the ureter 13,
Skin 29, fat 27. It is shown passing through a ligament 25 and a blood line 28.

The implant device 1 has an annular 1#17, the edge 17 forming an annular recess 87 between it and the anchoring means 15.

Such an annular recess 87 allows the conduit coupling means 19 to be secured to the implant device l, for example by means of a thread 41.

The conduit coupling means 19 are formed, for example, from a polyester textile product. In a preferred embodiment, at least a portion of the bonding material (from which the linkages are made) is coated with collagen.

Referring to FIG. 2, an embodiment is illustrated having two inlet sections 5a and 5b, which start at inlets 9a and 9b, respectively. Central axes 85a and 35b passing through the centers of inlets 9a and 9b, respectively, are approximately 1
inclined within the range of 73 degrees to 75 degrees (angle "Y" with respect to the central axis 8B passing through the outlet 11 in FIG.
). According to this embodiment, a single implant device l can be connected to two ureters 18.

Referring now to FIG. 3, a further embodiment of the inventive implant device is illustrated, in which the passageway 8 is rotatable together with the anchoring means 15. Preferably, the anchoring means 15 is secured around the passage 3 by joining the male part 41 and the female part 43. Such passage 80 turns allows for connection of the ureter 18 without occluding or entangling the ureter and thus restricting or obstructing flow through the ureter.
