Abstract
A single pass, large bore transseptal crossing catheter system is disclosed. An elongate, flexible tubular body has a proximal end, a distal end and an electrically conductive sidewall defining a central lumen. An insulation layer surrounds the sidewall and leaves exposed a first distal electrode tip. An inner conductive wire is provided, having a second distal electrode tip. The inner wire is axially movably extendable through the central lumen. A tubular insulation layer is provided in between the wire and the electrically conductive sidewall.
