Abstract
A novel subcutaneous tunnelling instrument and method for placing a subcutaneous catheter between two remote incisions in a patient, comprising making a subcutaneous tunnel by pushing a rod having an elongated bullet-shaped tip removably threaded upon male threads disposed at the distal end thereof into one incision and subcutaneously tunnelling to and out through the second incision, removing the bullet-shaped tip from the distal end of the rod, sliding the open end of a catheter over the male threads disposed at the distal end of the rod until the catheter abuts the rod, thereafter pulling the distal end of the rod back into the second incision and through the subcutaneous tunnel to and through the first incision, and thereafter removing the open end of the catheter from the male threads at the distal end of the rod.
