An improved catheter is provided. The catheter may include a deflectable member located at a distal end of a catheter body. The deflectable member may comprise an ultrasound transducer array. The deflectable member may be interconnected to the catheter body by a live hinge. The catheter may include a lumen extending from a proximal end of the catheter body to the distal end. The lumen may be used to deliver an interventional device to a point distal to the distal end of the catheter body. The deflectable member may be selectively deflectable in a pivot-like manner through an arc of at least 90 degrees. In embodiments where the deflectable member includes an ultrasound transducer array, the ultrasound transducer array may be operable to image both when aligned with the catheter body and when pivoted relative to the catheter body.

The instant invention is directed to a left ventricle valve for use in a left ventricle drain line. The left ventricle valve includes a unidirectional check valve having duckbill valve portion and a flange portion to movably cover vacuum vent openings. The vacuum vent openings are parallel to the flow passage of the left ventricle valve. The valve also has a pressure relief opening. The invention further contemplates the valve in an extracorporeal circuit for draining the left ventricle of a heart.
