ABSTRACT:
A long-term dialysis catheter system for use in a body of a patient includes a guide catheter having a guide lumen defined therein, wherein the guide lumen defines a distal guide orifice. The system also includes a tissue ingrowth member secured to an outer surface of the guide catheter. The system further includes an original dialysis catheter positionable between an original inserted position and an original removed position, wherein (i) the original dialysis catheter has an original ingress lumen and an original egress lumen defined therein, (ii) the original ingress lumen defines an original distal ingress orifice, and (iii) the original egress lumen defines an original distal egress orifice. The system also includes a replacement dialysis catheter positionable between a replacement inserted position and a replacement removed position, wherein (i) the replacement dialysis catheter has a replacement ingress lumen and a replacement egress lumen defined therein, (ii) the replacement ingress lumen defines a replacement distal ingress orifice, and (iii) the replacement egress lumen defines a replacement distal egress orifice. The original distal ingress orifice and the original distal egress orifice are positioned on an original distal segment of the original dialysis catheter which extends out of the distal guide orifice of the guide catheter when the original dialysis catheter is positioned within the guide lumen of the guide catheter. The replacement ingress orifice and the replacement egress orifice are positioned on a replacement distal segment of the replacement dialysis catheter which extends out of the distal guide orifice of the guide catheter when the replacement dialysis catheter is positioned within the guide lumen of the guide catheter. A medical procedure utilizing the long-term dialysis catheter system is also disclosed.
