  • Patent number: 6533782
    Abstract: A medical apparatus assembly (10) comprises a medical device (11) that includes a side port assembly 13 adapted to combine a first pathway (37) for infusion of fluids with a second pathway (38) for wire guide (12) into a first passageway (26) while the second passageway (27) includes the third pathway (39), which comprises a control member (24), such as an electrical wire. The side port assembly is configured such that the first passageway communicates with both a first port (16), such as a fitting for connecting to a syringe, and a second port (15) which includes a sealing mechanism (32), such as a Tuohy-Borst fitting, thereby allowing the wire guide to be preloaded, instead of requiring it to be removed prior to infusing fluids. Optionally, a third port (43) may be included when external communication with the second passageway, is desired, such as balloons or baskets.
