摘要：
1. A catheter comprising: an elongated catheter body, a distal end member mounted to the support at the distal end of the catheter body and defining a closed volume containing a fluid, an ultrasonic transducer submerged in said fluid and disposed to oscillate by performing rotational movement angularly range around the pivot axis within the enclosed volume, wherein the pivot axis is fixed relative to the distal end member and, first and second elements of a shape memory operatively interconnected with the ultrasonic transducer, wherein the first element with shape memory is activated by changing the state of the first element with shape memory, and a second element with shape memory is activated by changing the state of the second element with a shape memory wherein the first and second shape memory elements are activated, at least to the time offset, with respect to the influence of at least a portion of the oscillating rotary Navigating eniya ultrasonic preobrazovatelya.2. The catheter of claim 1, wherein the first and second elements of a shape memory operatively interconnected to the ultrasound transducer inside a closed volume, wherein the catheter further comprises first and second insulating layers disposed around at least a portion of the first and second shape memory elements , respectively, and are immersed in a fluid sredu.3. The catheter of claim 2, wherein the fluid is a zhidkost.4. A catheter according to claim 3, wherein each of the first and second insulating layers comprises ftorpolimer.5. A catheter according to
