Dialysis catheter
First Claim
1. A catheter assembly for at least semi-permanent retention in a patient, said assembly comprising:
- an elongate catheter having a proximal end, a distal end and at least one lumen extending between the ends; and
a fibrosing means selectively positionable around a portion of the catheter at a selected distance from the distal end for promoting a growth of scar tissue for anchoring the catheter assembly in the patient, at least one end of the catheter being trimmable for achieving a selected length between the proximal and distal ends of the catheter.

Abstract
A catheter assembly includes catheter having proximal and distal ends and at least one lumen extending between the ends. At least one end of the catheter is formed from a material that can be trimmed to achieve a selected length for the catheter. A tubular connector is telescoped over the catheter and a hub is joined to the tubular connector. Proximal portions of the hub are configured for connection to a medical apparatus. A cuff is mounted around the tubular connector or the catheter. The cuff is formed from a material that will permit or promote the growth of scar tissue for anchoring the catheter device at least on a semi-permanent basis in a patient.

12. A catheter assembly for at least semi-permanent retention in a patient, said assembly comprising:
-
an elongate catheter having a proximal end, a distal end and at least one lumen extending between the ends;
a subcutaneous tube having a proximal end for disposition externally of the patient, a distal end for subcutaneous disposition in the patient and a lumen extending between the ends, portions of the catheter substantially adjacent the proximal end of the catheter passing through the lumen of the subcutaneous tube;
means for affixing the subcutaneous tube axially relative to the catheter; and
a fibrosing means surrounding a portion of the catheter for promoting a growth scar tissue for anchoring the catheter assembly in the patient. - View Dependent Claims (13, 14, 15)

16. A method for implanting a dialysis catheter in a patient, the method comprising the steps of:
-
providing a dialysis catheter having a proximal end, a distal end and first and second lumens extending between the ends, the first and second lumens being offset from one another at the distal end of the catheter in a longitudinal direction of the catheter;
inserting the distal end of the catheter to a targeted location in a blood vessel of a patient so that the proximal end of the catheter is disposed externally of the patient and so that an intermediate portion of the catheter passes through a subcutaneous tunnel spaced from the blood vessel;
mounting a fibrosing cuff around the catheter;
trimming portions of the catheter adjacent the proximal end to define a trimmed proximal end; and
affixing a hub to the trimmed proximal end. - View Dependent Claims (17, 18)
