Abstract: The non-surgical method of installing a subcutaneously tunneled semipermanent catheter through the skin and into a central vein which utilizes an introducer catheter which has a pair of proximal ports, distal port, and an intermediate port located between the proximal ports and the distal port. The distal section of the introducer catheter is to be positioned within the central vein and the intermediate port is positioned exterior of but directly adjacent the vein and under the skin. A guide wire redirecting catheter is inserted into the introducer catheter and engages with the intermediate port. A sharp tipped guide wire is inserted through the guide wire redirecting catheter and is discharged from the redirecting catheter and travels subcutaneously some distance before penetrating the skin. The portion of the sharp tipped guide wire within the introducer catheter is then prolapsed into the distal portion of the introducer catheter.
