CATHETER WITH TRANS-LUMINAL GAS PATHWAY Abstract A catheter having at least two separate lumens, one for conveying liquids to and from a port spaced substantially from the distal end of the catheter and the other for enclosing an electrical conductor which extends to a point distal to the port. The two lumens are separated by a longitudinal septum and combine to perform a third function -- that of containing a gas required in connection with the operation of a pressure responsive element adjacent the catheter's distal end. The septum is provided with an aperture -through which the gas chamber ox pathway switches from one lumen to the other. A sealant plug located in the lumen for liquid flow prevents contact between such liquid and both the electrical conductor and the gas within the pathway. Methods for forming such a catheter are also disclosed.
