Catheter has been improved

摘要

I will provide a catheter that has been improved. The catheter may comprise a member which is bent located at the distal end of the catheter body. The member to be bent, can be provided with an ultrasound transducer array. The member to be bent, can be connected to the catheter body by a living hinge. The catheter may include a lumen distal end from the proximal end of the catheter body extends. This lumen can be used to deliver to a point distal to the distal end of the catheter body the interventional device. Member to be bent, can be bent in the range of arc of at least 90 degrees and then selectively as a pivot. In embodiments in which a member to be bent comprises an ultrasound transducer array, and when it is aligned with the catheter body, the ultrasound transducer array can acquire images both when it is pivoted relative to the catheter body.
