    Abstract: A cardiac diagnosis and treatment system comprises a support carrying at least two electrodes. A conductor is associated with the support for selectively directing electrical signals to and from each electrode. The conductor includes a first buss for delivering power from an external power source, a second buss for transmitting electrode signals to an external signal processor, and a third buss for receiving control signals from an external signal source to multiplex the electrode signals from the electrodes through the second buss. A conduction line conducts power, control signals, and electrode signals from the external sources to the conductor.

    Abstract: A catheter has a handle and a guide tube enclosing an interior bore. The guide tube has a proximal end and a distal end. A friction sleeve joins the proximal end of the guide tube to the handle. The friction sleeve extends from the handle and grips a portion of the guide tube beyond the handle. The friction sleeve forms a hand grip for the user beyond the confines of the handle. It also serves to effectively transmit torque applied at the handle to the distal end of the guide tube.
