摘要:
A system for advancing a needle through a vasculature to an injection site at the heart of a patient includes a guide catheter with a reflective distal tip. Also included is an imaging unit that is mounted on the catheter to radiate an energy field. Structurally, a distal portion of the catheter is biased to bend into a predetermined configuration that will position the distal end of the catheter for interception by the energy field. If necessary, coincidence of the reflective tip with the energy field is established by moving the energy field along the length of the guide catheter. With coincidence, the reflective tip reflects a signal that is useful for advancement of the needle from the guide catheter and into the injection site.
摘要(中):
用于将针通过脉管系统推进到患者心脏的注射部位的系统包括具有反射性远侧末端的引导导管。 还包括安装在导管上以辐射能量场的成像单元。 在结构上,导管的远端部分被偏压以弯曲成预定的构造,其将定位导管的远端以通过能量场拦截。 如果需要,通过沿引导导管的长度移动能量场来建立反射尖端与能量场的一致性。 巧合的是,反射尖端反映了一种信号,该信号可用于从引导导管进入针头并进入注射部位。
