Abstract
A method of inserting a multi-lumen catheter assembly. First, an incision is made near the area to be catheterized. The proximal portion of the multi-lumen catheter tube is then inserted into the area to be catheterized. A subcutaneous tunnel is created, and the first end of the tunnel is near the incision. The catheter tube is then routed through the subcutaneous tunnel and pulled tube through a second end of the subcutaneous tunnel. The hub body is then securely attached to the catheter tube by connecting the connection cover to the hub body by threaded engagement. In a preferred embodiment the hub body is attached to the catheter tube by backfitting the connection cover over the catheter tube. A compression sleeve is also backfit over the catheter tube. The cannulae of the hub body are inserted into the lumens of the catheter tube to create fluid communication therebetween. The connection between the cannulae and the first and the catheter tube is compressed by sliding the compression sleeve over the cannulae that have been inserted into the catheter tube.

17. A method for inserting a multi-lumen hemodialysis catheter assembly into an area to be catheterized, the multi-lumen hemodialysis catheter assembly having a multi-lumen catheter tube having a distal portion and a proximal portion, the method comprising the steps of:
-
a. making an insertion incision;
b. inserting the proximal portion of the multi-lumen catheter tube through the incision and into the area to be catheterized;
c. creating a subcutaneous tunnel having a first end and a second end, wherein the first end is closer than the second end to the insertion incision;
d. routing the distal portion of the catheter tube through the subcutaneous tunnel while the proximal portion of the multi-lumen catheter tube remains in the area to be catheterized, the distal portion entering the first end and exiting the second end of the subcutaneous tunnel;
e. attaching the distal portion of the catheter tube to a device which supplies fluid to a first lumen of the multi-lumen catheter and withdraws fluid from a second lumen of the multi-lumen catheter; and
f. conducting hemodialysis through the multi-lumen hemodialysis catheter assembly. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for inserting a hemodialysis catheter into a vein, the hemodialysis catheter assembly comprising a multi-lumen catheter tube having a distal portion and a proximal portion, the method comprising the steps of:
-
a. making an insertion incision extending from a skin portion of a patient into the vein;
b. inserting the proximal portion of the multi-lumen catheter tube through the incision and into the vein;
c. creating a subcutaneous tunnel having a first end and a second end, the first end near the insertion incision;
d. attaching a trocar to the distal portion of the catheter tube;
e. routing the trocar and the attached distal portion of the catheter tube through the subcutaneous tunnel;
f. disconnecting the trocar from the catheter tube;
g. attaching the distal portion of the catheter tube to a device which supplies fluid to a first lumen of the multi-lumen catheter and withdraws fluid from a second lumen of the multi-lumen catheter; and
h. conducting hemodialysis through the hemodialysis catheter. - View Dependent Claims (31, 32, 33, 34)
