Claims19
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, the method comprising the steps of:
- a. accessing an area to be catheterized and creating an access site;
- b. inserting an introducer sheath into the area to be catheterized;
- c. inserting a first guide wire and a second guide wire into the introducer sheath;
- d. at least partially inserting a first dilator over the first guide wire and a second dilator over the second guide wire into the area to be catheterized;
- e. removing the first dilator and the second dilator and blocking the flow of one or more of blood and air into and out of the area to be catheterized;
- f. passing the distal portion of the first catheter over the first guide wire and passing the distal portion of the second catheter over the second guide wire;
- and
- g. inserting each of the first and second catheters in juxtaposed relation into the area to be catheterized.
A method for inserting a multiple catheter assembly into an area of a body to be catheterized, the method comprising the steps of:
- a. accessing an area to be catheterized;
- b. inserting an introducer sheath into the area to be catheterized;
- c. inserting a first guide wire and a second guide wire into the area to be catheterized by passing the guide wires through the introducer sheath;
- d. inserting and then removing a first dilator and a second dilator into the area to be catheterized;
- and
- e. inserting a first catheter and a second catheter into the area to be catheterized by passing the first catheter over the first guide wire and the second catheter over the second guide wire and threading each into the area to be catheterized.
