Imaging probe housing with fluid flushing

An imaging probe for use in a catheter for ultrasonic imaging, the imaging probe comprising:

• a transducer backing;
• a transducer disposed near a distal end of the imaging probe, the transducer configured to generate and receive ultrasonic waves, the transducer including a first surface and a second surface that is opposite the first surface, the first surface facing the transducer backing, and the second surface comprising a proximal edge and a distal edge, the proximal edge being axially closer to a proximal end of the imaging probe, the distal edge being axially closer to the distal end of the imaging probe;
• wherein the second surface is inclined with respect to a catheter center axis so that the proximal edge of the second surface is radially closer to the catheter center axis than the distal edge of the second surface, and
• wherein the imaging probe further comprises a distal tip wall disposed distal to the transducer, the distal tip wall including a distal tip wall opening, such that a direction of the inclined second surface and a position of the distal tip wall opening allow a fluid to flow distally along the catheter, to pass over the second surface of the transducer and to exit the catheter through the distal tip wall opening.
