Abstract: A door assembly including a first glass pane, a second glass pane, and a spacer positioned between the first glass pane and the second glass pane such that the first pane and the second pane are separated by the spacer. The door assembly also includes an element that is coupled to the first glass pane and the second glass pane and positioned exterior of the spacer. The spacer and the element cooperate to at least partially define a seal passage, and a clear material is disposed in the seal passage to seal the space, the clear material configured to provide structural support to the assembly.

Abstract: A method of forming 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 piercing tool is inserted through the port at an angle to form the aperture distally of the port. The wire is threaded through one duct, through the aperture and through the second duct. Finally a sealable liquid sealing plug is inserted into the area distally of the port for sealing purposes.
