In a transfer device having a fluid passageway therein in fluid communication with an integral fluid control valve and useable in a system for intraluminal treatment of a selected site in a body of a patient by at least one treating element advanced from the transfer device into a lumen of a catheter by means of pressurized fluid. The fluid passageway of the transfer device is in communication with a source of pressurized fluid, the improvement comprising a pressure indicator in fluid communication with the fluid passageway and interposed between the fluid passageway and the fluid control valve. The said pressure indicator includes a transparent elongated housing having a first portion of a first inside dimension and viewable by a user of the transfer device, a piston slidingly received within said housing, and sized to sealingly engage said first portion. The said piston is biased into said first portion of said housing. An inlet port in said first portion in communication with the source of pressurized fluid through the fluid passageway, whereby the relative position of said piston in said first portion of said housing provides a visual indication of the relative fluid pressure.
