An ultrasonic transducer assembly includes a conduit that defines a lumen, and the lumen carries a flexible circuit. The flexible circuit can take several forms. In one form the circuit is folded at first and second fold lines, and at least one of the folds is oriented obliquely to the longitudinal axis of conduit. In another form the flexible circuit includes an end portion that defines a plurality of substantially parallel grooves, each groove aligned with and exposing a respective one of the conductors of the circuit. Additional conductors are positioned in respective ones of the grooves and are electrically connected with the respective conductors of the flexible circuit. |
