Stent range transducers

摘要

A system for delivering and positioning a stent within a bifurcated body lumen includes a stent delivery system including a catheter, an expansion device, and an ultrasound transducer. The ultrasound transducer is configured for transmitting and receiving signals and for imaging of a body lumen so as to locate an ostium of a branch vessel and facilitate alignment of the stent side hole with the ostium.
