Method for inserting a multiple catheter assembly
First Claim
1. A method for inserting a multiple catheter assembly into an area of a body to be catheterized, the assembly comprising a first and a second catheter, each catheter having a distal portion and a proximal portion, the first catheter for withdrawing fluid from the area and the second catheter for delivering fluid to the area, the first and second catheters being independently movable with respect to each other along their entire length, the method comprising the steps of:
- (a) making an incision near the area;
(b) inserting the distal portions of the first and second catheters in juxtaposed relation through the incision and through a single insertion site into the area;
(c) adjusting a longitudinal distance between the proximal portions of the first and second catheters to provide a predetermined longitudinal distance between the distal portions of the first and second catheters within the area; and
(d) securing the proximal portions of the first and second catheters.

Abstract
A method is provided for inserting a multiple catheter assembly into an area of a body to be catheterized through a single incision. Two independent catheters which are independently movable with respect to each other, or unattached to each other, along their entire length are inserted into the single incision. In use, the first catheter withdraws fluid from the area and the second catheter delivers fluid to the area. As part of the insertion method, the longitudinal distance between proximal portions of the two catheters are adjusted to provide a predetermined longitudinal distance between distal portions of the two catheters within the area.

19. In a method for inserting a multiple catheter assembly into an area of a body to be catheterized, the assembly comprising a first and a second catheter, each catheter having a distal portion and a proximal portion, the first catheter for withdrawing fluid from the area and the second catheter for delivering fluid to the area, the first and second catheters being unattached to each other along their entire length, the improvement comprising the steps of:
-
(a) inserting the distal portions of the first and second catheters in juxtaposed relation into the area through a single incision made near the area to be catheterized and through a single insertion site into the vessel; (b) adjusting a longitudinal distance between the proximal portions of the first and second catheters to provide a predetermined longitudinal distance between the distal portions of the first and second catheters within the area; and (c) securing the proximal portions of the first and second catheters. - View Dependent Claims (20)
