Abstract
An image diagnosis catheter is disclosed, which includes: a sheath inserted into a living body; an ultrasound vibrator capable of transmitting and receiving ultrasound in the sheath; a housing holding the ultrasound vibrator in the sheath; and a drive shaft attached to a proximal side of the housing and rotatable in the sheath, in which an ultrasound transmitting/receiving surface of the ultrasound vibrator facing a radial direction of the sheath is inclined with respect to an extension direction of the sheath such that a distal end of the ultrasound transmitting/receiving surface is closer to an inner peripheral surface of the sheath than a proximal end of the ultrasound transmitting/receiving surface, and the housing does not block a distal side of the ultrasound vibrator in an in-plane direction of the ultrasound transmitting/receiving surface.
