Peritoneal Conduit

Abstract

The Peritoneal Conduit is a medical device composed of tubing with an integrated collar made of a flexible and non-absorbable material for surgical implantation to create a conduit for passage of a catheter between two body cavities. The Peritoneal Conduit has a hollow center that spans from one end (shorter proximal portion) to the other end (longer distal portion). The catheter that will be being placed through the Peritoneal Conduit will enter into the proximal portion and will pass through the hollow center of the Peritoneal Conduit to emerge from the distal portion. The catheter is then secured to the Peritoneal Conduit using one suture that is tied around the groove in the proximal portion of the Peritoneal Conduit. The Peritoneal Conduit itself is secured in placed using two sutures that are placed through the integrated collar at the junction of the proximal and distal portions of the Peritoneal Conduit.

Claims

1. A Peritoneal Conduit comprising: a tubing having a first and a second end; and an integrated collar; wherein the said integrated collar is near one end of the said tubing.

2. The invention of claim 1 wherein the tubing and integrated collar are made of a flexible and non-absorbable material such as silicone/Silastic®.

3. The invention of claim 1 wherein there is a thin groove in the outside wall of the tubing between the integrated collar and the first end.

4. The invention of claim 1 wherein the tubing has a hollow center throughout its entire length that spans the tubing from its first end to the second end.

5. The invention of claim 1 wherein the tubing may be trimmed at the first end and/or the second end in order to fit the biological tissue in which it is implanted.

6. The invention of claim 1 wherein the integrated collar may be of any shape, size, or thickness; and it exists for the purpose of securing the invention to surrounding tissues after implantation.

7. The invention of claim 1 wherein the device is used for surgical implantation in order to create a permanent conduit through the said hollow center from one anatomic space into another anatomic space across biological barriers.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] There are 5 figures that are included with this application. The images are not drawn to scale and are intended to depict the general appearance and the salient features of the Peritoneal Conduit (PC). FIG. 1 is a schematic drawing showing the oblique side view of the PC. FIG. 2 is a schematic drawing showing the side view of the PC. FIG. 3 is a schematic drawing showing the bottom view of the PC. FIG. 4 is a schematic drawing showing the top view of the PC. FIG. 5 is a schematic drawing showing the side view of the Peritoneal Conduit after implantation in tissue (the example used here is the abdominal tissue with some of its layers such as superficial fascia, muscle, deep facia, peritoneum, and the abdominal cavity).
