Abstract
An access system for providing subcutaneous access to a vessel, organ, or body cavity comprises a needle and a rigid or semi-rigid tunneler arranged coaxially around the needle, such that the needle moves slidably within the tunneler. Optionally a sheath may be positioned coaxial to the tunneler. The tunneler-needle system is inserted through an incision in a patient's skin to initiate a procedure whereby a catheter is inserted into the vessel, organ, or body cavity.
