Ultra-thin acoustic transducer and balloon catheter using same in imaging array subassembly

摘要: An array of miniature ultrasound crystals mounted on preassembled subassembly which is, in turn, a small lumen catheter provides dimensional and other quantitative information relating to arterial wall geometry character at disease or obstruction sites. Balloons also the make it possible use for angioplasty (PCTA) procedure while actually imaging, real time, artery being dilatated unblocked by procedure. Efficient, highly transducers are presented along with several different configurations structure containing fluid lumen, through-lumen, electrical microcable assemblies conducting signals from transducers.
