A medical device tunneling system, and a method of using the same, to subcutaneously route trocars, also commonly referred to as tunnelers, or introducers, having a cannula, stylet, and a guidewire stylet, inside a patient during a surgical procedure, such as a ventriculoperitoneal hydrocephalus shunt implantation, from a proximal entry point to a distal end point, in order to subcutaneously route and implant a medical device, such as shunt tubing, in a patient. |

1. A method of subcutaneously routing tubing within a human patient, comprising:
making a first incision; inserting at least a portion of a stylet into a cannula, wherein the cannula comprises a hollow passage; inserting at least a portion of the cannula and stylet into the patient subcutaneously; routing the cannula and stylet to a location proximate to an area of the patient's skull; optionally removing the stylet from the cannula; inserting a guidewire through the hollow passage of the cannula, and/or optionally through the stylet; steering the guidewire around the area and to a second incision located proximate the patient's skull, wherein said steering is achieved without the use of a third incision; attaching the tubing to the guidewire through the second incision; and retracting the guidewire, attached tubing, and/or stylet via the first incision. |
