Abstract
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.
