Abstract
A guiding sheath has a hemostatic valve and a central lumen into which a diagnostic or treatment catheter can be introduced and guided into a patient. The hemostatic valve also includes an electrically conducting element or proximity sensing element on its proximal end that interacts with a second electrically conducting element or proximity sensing element on a proximal end of the diagnostic or treatment catheter that can be passed through the central lumen of the guiding sheath and into the patient's heart. The interaction between the two electrically conducting elements or proximity sensing elements enables the location of the distal end of the diagnostic or treatment catheter in the patient's heart without the need for irradiating the patient.
