Abstract
In order to provide a catheter which can be operated even when it is deformed inside a bent blood vessel and whose movable part can be easily bent and the movable part thus bent is firmly kept in this shape, a catheter includes: a fluid-driven actuator including: a balloon; a restricting member for restricting inflation of the balloon in a short axis direction of the catheter; and a tube which is less stretchable in a long axis direction of the catheter than the balloon is, according to a cross-sectional view of the fluid-driven actuator taken along the short axis direction of the catheter, the restricting member.
Claims11
A catheter comprising:
- a fluid-driven actuator including:
- a balloon;
- a restricting member for restricting inflation of the balloon in a short axis direction of the catheter;
- and
- a tube which is less stretchable in a long axis direction of the catheter than the balloon is,
- according to a cross-sectional view of the fluid-driven actuator taken along the short axis direction of the catheter, the tube being eccentrically provided with respect to the restricting member.
