Separable peritoneal dialysis catheter
First Claim
1. A peritoneal dialysis catheter which comprises a distal tubular section and a proximal tubular section, and nonintegral, tubular connector means positionable in connected relation with respective ends of said proximal and distal tubular sections in sealed flow relation, at least one of said tubular sections carrying means for attachment of said catheter to living tissue adjacent said tubular connector means, whereby said distal tubular section may be surgically implanted in the peritoneal cavity and the proximal tubular section may be surgically implanted in the chest of a patient with an end thereof protruding from the chest, and said respective ends may be connected to each other through said tubular connector means as said tubular section are surgically implanted.

Abstract
A peritoneal dialysis catheter comprises a distal tubular section and a proximal tubular section, connected together by a nonintegral tubular connector so that the respective sections are connected together in sealed flow relation. Such a catheter may be surgically implanted in the peritoneal cavity, extending to the chest of the patient with an end thereof protruding from the chest. The respective ends of the catheter section may be connected to each other through the tubular connector as the tubular sections are surgically implanted, and typically after such implantation is substantially complete.
