Endo-luminal ultrasonic instrument and method for its use |
March 8, 1994 |
| An endo-luminal ultrasonic instrument has a motor with a rotatable drive shaft that oscillates back and forth. A flexible catheter sheath is coupled at one end to the motor to oscillate with the drive shaft. The sheath has an axis about which it oscillates and a diameter sized to fit |

Multiple transducer selector |
April 27, 1993 |
| An ultrasound imager supports several ultrasonic transducers simultaneously. The imager polls the transducer connection ports to determine which transducers are connected to which port and displays attributes of each transducer in conjunction with a port identification on the screen. |
