DIAGNOSTIC IMAGING CATHETER |
| 摘要 |
A diagnostic imaging catheter is disclosed, which includes a sheath that is inserted into a body-cavity in a living body, an ultrasound transducer that is inserted into the sheath and is able to transmit and receive an ultrasound wave, a housing that accommodates the ultrasound transducer, and a drive shaft that includes the housing at the distal end and is rotatably provided inside the sheath. A first region A1 positioned on the distal side closer than the ultrasound transducer in the housing and a second region A2 positioned on the proximal side closer than the ultrasound transducer in the housing are formed so as to have X-ray contrast properties higher than that of an intermediate region A3 positioned between the first region and the second region. |

1. A diagnostic imaging catheter comprising:
a sheath that is inserted into a body-cavity in a living body; an ultrasound transducer that is inserted into the sheath and configured to transmit and receive an ultrasound wave; a housing that accommodates the ultrasound transducer; and a drive shaft that includes the housing at the distal end and is rotatably provided inside the sheath, wherein a first region positioned on the distal side closer than the ultrasound transducer in the housing and a second region positioned on the proximal side closer than the ultrasound transducer in the housing are formed so as to have X-ray contrast properties higher than that of an intermediate region positioned between the first region and the second region. |
