    摘要: A catheter system has a balloon angioplasty device disposed about a common lumen near its distal end. The balloon catheter is pre-fitted with a stent which is deployed when the balloon is inflated. The common lumen is in communication with multiple lumens within a proximal region of the catheter body to allow for positioning of the catheter over a movable guide wire and convenient delivery of imaging or interventional devices to a desired region of a body passageway being treated. The procedure for stent deployment optionally includes steps of imaging a lumen by ultrasound before and after stent deployment to identify the site at which a stent is needed, to confirm that the stent is being and has been deployed at a longitudinal position which does not overlap a branched segment of the body passageway, and to ensure that the stent has been radially opened to an optimum diameter.

    摘要: An ultrasonic transducer assembly includes a transducer mounted in a housing, the transducer including a piezoelectric element and respective matching and backing layers formed on the opposite sides thereof, the transducer mounted in the housing encapsulated with a non-conductive potting material. A portion of the matching layer is removed, e.g., by etching, to expose a portion of an underlying electrode formed between the piezoelectric element and the matching layer. A portion of the non-conductive potting material between the etched portion of the matching layer and a signal wire disposed in the housing is also removed. The respective voided portions of the matching layer and non-conductive potting material are filled with an electrically conductive matching material to electrically couple the electrode, and, thus, the piezoelectric element, to the signal wire.
