Implantable Peritoneal Dialysis Catheter with Port IPD Catheter

Abstract

Peritoneal dialysis is delivered via implementation of the total implantable system disclosed. The system is composed of several components. The extended surface area port, equipped with an internal support pillar, is implanted beneath the subcutaneous tissue. The catheter portion is tunneled under the subcutaneous tissue until it reaches the abdomen where it enters the peritoneal cavity. The distal/terminating end of the catheter resides in the peritoneal cavity and is designed with an inner perforated distal catheter, circumferentially enclosed by an outer perforated sheath, creating an anti-occlusion technology system. The distal end of the sheath is designed with an anti-clog tip. Port and system access is achieved via hypodermic needle. Dialysis solution is infused and evacuated via the same modalities.

Claims

1. A totally implantable indwelling peritoneal dialysis catheter that is comprised of several components. Component 1 is called the port and is implanted under subcutaneous tissue of the body at variable sites, depending on the patient's anatomy and surgeon's preference. (Primarily at the abdominal and thoracic region of the body.) Component 2, the implantable catheter. The proximal terminal end of the catheter connects to the port. The proximal and middle portion of the catheter are tunneled under the subcutaneous tissue until it reaches the abdominal wall near the peri-umbilical area. The distal portion of the catheter enters and terminates in the peritoneal cavity. Component 3 is the external perforated sheath with anti-collapsible rib spacers, which is a circumferential covering over the terminating distal catheter.

2. A totally implantable peritoneal dialysis catheter of claim 1, having an injection port (accessible via a hypodermic needle, as one of its components) located at the proximal terminal end of the catheter. (This port is used to infuse a dialysate solution. Additionally, this port is used to evacuate the dialysate solution that is dwelling within the peritoneum for a prescribed length of time.)

3. A totally implantable peritoneal dialysis catheter of claim 1, having an anti-occlusion technology system comprised of anti-collapsible rib spacers for prevention of omental occlusion.

4. A totally implantable peritoneal dialysis catheter of claim 3, containing perforated distal catheter tube.

5. A totally implantable peritoneal dialysis catheter of claim 2, containing an extended surface area (increased diameter) injection access port. (Allows for multiple injections via the hypodermic needle during the life of the device.)

6. A totally implantable peritoneal dialysis catheter of claim 5, containing an internal center pillar support located internally at center port, to prevent the collapsing of the silicone injection diaphragm portion of the port.

7. A totally implantable peritoneal dialysis catheter of claim 1, adjustable in length to accommodate various patient sizes and anatomical variances.

8. A totally implantable peritoneal dialysis catheter of claim 4, containing a rounded anti-clog tip to prevent unintended visceral puncture.

9. A totally implantable peritoneal dialysis catheter of claim 3, contains a perforated external sheath for prevention of omentum occlusion.

DETAILED DESCRIPTION OF DRAWINGS

[0015] The present invention can be manufactured in a variety of configurations, it is the currently presented manifestation (designs and descriptions) in this declaration that is prevalent. This manifestation is the exemplification of the general scientific theorems and the applications of the invention to include documentation and does not limit the broad aspects of the invention only to the provided artwork and documentation for the manifestation.

[0016] A novel catheter in accordance with the application is exemplified in its totality via this present work in FIG. 1. FIG. 2 is exploded to give perspective to FIG. 1 for comprehension of practical application. FIG. 2 will also shed light as to the functionality of the invention together with a descriptive analysis. The catheter is fully implanted surgically, as exhibited in FIG. 5. The catheter can be implanted through a small incision via laparoscopic procedure, or it can be implanted by way of mini laparotomy surgery, which is dependent on a larger incision for insertion. The catheter can be adjusted to accommodate the patients' size and anatomical differences. With either technique, access to the peritoneum is achieved by way of a peri-umbilical puncture or incision. A stylet is inserted down the center Lumen of the catheter to give it firmness. The distal portion of the catheter is illustrated in FIG. 3-A, 3-B C-6, FIG. 5-6B, FIG. 6-6B, FIG. 7-6B, and FIG. 8-6B is guided into the abdomen at the pelvic region and the stylet is then removed. A surgical instrument, a tunneler is utilized to create a tunnel beneath the subcutaneous tissue terminating at the site of the surgeon's choice. In these illustrations, the terminal point would be the patient's right upper thoracic region near the clavicle. A small incision is made just under the destination site for the port as Illustrated in FIGS. 5 1 and 5-2. Also, this applies to FIG. 6-3. The proximal catheter Illustrated in FIG. 6-6A is fed through the tunneler to the upper incision site at the upper thoracic region. The tunneler is removed, exposing the proximal end of the catheter as observed in 6-6a. A pocket is then created under the subcutaneous tissue by the surgeon. This pocket will house or encapsulate the port as seen and FIG. 3-D, 3-E. The proximal end of the catheter seen in FIGS. 5-A and 6-A is then connected to the port, FIG. 3-D, 3-E. The port is then placed and secured within the prepared pocket under the subcutaneous tissue after a patency test with heparinized saline. The surgical incision is then closed, and the device is left until wound healing until wound healing.

[0017] After the predetermined healing period has taken place, the peritoneal dialysis procedure can begin. The peritoneal dialysate fluid tubing will terminate at the distal portion by being connected to a hypodermic needle, which is illustrated in FIGS. 2-7 and FIG. 3-B, C 7. The dialysis solution will then flow from its source into the port, FIG. 3-B, 3-E. The fluid will flow through the needle after the needle has been inserted into a silicone diaphragm FIG. 3-2. The dialysis solution will flow from the needle FIGS. 3-7 and a holding chamber FIG. 3-1 and FIG. 2-1. The holding chamber will contain a support pillar that will add support and prevent collapsing of the diaphragm FIG. 2-3 FIG. 3-2. The dialysis solution will then flow down the catheter from proximal to distal FIG. 5-6A and FIG. 5-6B. The dialysis solution will then exit the distal terminal portion of the catheter in FIGS. 5-4 and 5-5 entering the peritoneal cavity. After dialysis solution has completed its dwell time in the peritoneal cavity, vacuum pressure will be applied to the peritoneal cavity via a needle FIG. 2-7, FIG. 3-B7 FIG. 3-C7 This will create a negative pressure in the abdominal cavity, thus evacuating the spent dialysis solution from the peritoneal cavity. The dialysate solution will travel back through the distal portion of the catheter FIG. 3-5. The dialysate solution will flow through the external sheath of the distal catheter FIG. 5-5. FIG. 8-5, FIG. 7-5. The outer sheet of the distal catheter FIG. 4A-5 will act as a barrier between the internal organs and the inner distal catheter FIG. 2-4 and FIG. 5-4. The outer cannula FIG. 4A will be separated by ribs FIG. 4B to prevent collapse under vacuum pressure. The spent dialysate solution will flow back up and exit the catheter in the opposite direction in which it entered.
