Device and method for vascular access
First Claim
1. A method for treating a patient, comprising:
- providing a first and second conduit of a vascular access system;
accessing a vein at a first access site;
inserting the first conduit of the vascular access system into the vein;
forming a subcutaneous pathway between the first access site and an intermediate access site;
accessing an artery at a second access site;
attaching the second conduit to an artery through the second access site; and
positioning the first conduit and second conduit of the vascular access system in the subcutaneous pathway;
accessing an end of the first conduit and an end of the second conduit through the intermediate access site;
connecting the end of the first conduit and the end of the second conduit and reinserting the connected ends of the first conduit and the second conduit through the intermediate access site.

Abstract
Vascular access systems for performing hemodialysis are disclosed. The vascular access system contemplates a catheter section adapted for insertion into a vein and a graft section adapted for attachment to an artery. The catheter section may have metal or polymer wall reinforcements that allow the use of thin-walled, small outer diameter conduits for the vascular access system. One or more of the adhered, embedded or bonded conduit reinforcement structures may be removable without significant damage to the conduit sections to facilitate attachment of the sections, or to a connector between the sections. Various self-sealing materials are provided for use in the vascular access system, as well as temporary access sites and flow control/sensor systems.
