Abstract
A diagnostic imaging catheter includes: a drive shaft including a signal transmitter and receiver at a distal end portion and configured to rotate and move forward and backward; a support tube on an outer periphery of the drive shaft along an axial direction and configured to move forward and backward i with the drive shaft; a sheath in which the drive shaft is positioned; a relay connector connected to a proximal end of the sheath; and a sealing member providing a seal between the relay connector and the support tube at a position proximal of the sheath proximal end. The relay connector includes a main lumen extending from the sealing member to the sheath proximal end and an injection lumen communicating with the main lumen at a communication port. A distal end of the support tube is movable to a position proximal of the front edge of the communication port.
