Ultrasonic catheter, comprises integrated ducts dispensing contrast media for ultrasonic inspection as well as for X-raying

摘要

A first hollow shaft (3) containing the signal duct (4) and the drive shaft (5) for the image creating device (6) and provided with an ultrasonic sensor at the front is accommodated inside the long cylindrical catheter (1). Transparent windows (7) facilitate the emission of the signals reflected by the tissue walls and returned to the image creating device (6). A second hollow shaft (9) is used for the supply with a contrast medium released through one or two openings (10) at the front (8). A contrast medium required for X-raying can be guided through a third hollow shaft (11).
