摘要

The present invention provides for integrated coaxial drive cables and transmission lines for use in catheter systems. In one embodiment, the invention comprises a catheter system comprising a catheter body having a distal end, a proximal end and a working lumen. A drive cable extends through the catheter body's working lumen and comprises an outerwound layer, an innerwound layer and a central lumen. A coaxial cable is provided comprising a conducting core and an insulation layer. The coaxial cable is disposed to extend through and fill the central lumen.
