Abstract
A system for positioning a catheter within vasculature of a patient includes an introducer having a proximal hub configured to remain outside of the patient, an introducer catheter extending from the proximal hub, and a body forming a hub lumen. The system also includes the catheter, the catheter being sized and shaped to pass through the hub lumen and through the introducer catheter into the vasculature of the patient. The introducer includes a linear encoder sensor and the catheter includes a linear encoder scale so that, as the catheter passes through the introducer, the linear encoder sensor is configured to generate a signal indicative of an axial distance which the catheter has traveled relative to the introducer.
