Abstract
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.
Claims12
A method of subcutaneously routing tubing within a human patient as part of a surgical procedure for cerebrospinal fluid diversion, comprising:
- in a torso area of the patient;
- 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 through the first skin incision;
- extravascularly routing the cannula and stylet from the first skin incision to an area adjacent an external surface of the patient's skull;
- inserting a guidewire through the hollow passage of the cannula;
- steering the guidewire around the area and to a second skin incision located proximate the external surface of the patient's skull, wherein said steering is achieved without the use of a third incision;
- attaching tubing to the guidewire, the attached tubing comprising drainage tubing for allowing flow of cerebrospinal fluid therethrogh;
- and
- retracting the guidewire and attached tubing, wherein the attached tubing is disposed subcutaneously and extends between the first and second skin incisions.
