ABSTRACT:
A catheter having at least two separate lumens, one containing a gas required in connection with the operation of a pressure responsive element adjacent the catheter's distal end and the other for conveying liquid to and from a port spaced proximally from the pressure responsive element. The two lumens are separated by a longitudinal septum and combine to perform a third function--that of enclosing an electrical conductor which extends through that portion of the gas-containing lumen proximal to the port and through that portion of the liquid-conveying lumen beyond the port. The conductor switches from one lumen to the other through a sealed aperture in the septum. A method of forming such a catheter is also disclosed.
